Any Excel Mobile experts?

I want to do a little sales script tree* for my pocket PC - I could do it in html, but I reckon the speed, even on local files, would not be what I'd need. I need to simply be able to select options and have different screens come up quickly, depending on those choices.
I've no money for any programming packages, so I figured Excel could do it. But Excel Moble looks like it doesn't let me move between sheets using hyperlinks or buttons.... plus does it top out at three sheets??
Anyone with any ideas for a solution/workaround?
*Something like this:
Screen 1 - Intro
"Speaking to Decision Maker? YES / NO"
Screen 2 - Gatekeeper (four options for example)
"Not interested / not present / too busy / why you phoning?"
[...]
Screen 10 - Decision Maker Refusals
"Not interested / In contract / Too busy / Getting great deal / Don't want a visit (etc)"
That kinda thing....

Actually, scratch that - did a bit of playing around with Dreamweaver and Opera Mobile, and it's a plenty fast enough solution.
And using my own self-made GIF buttons in layers it give me total control to tailor it... so now I know what I'll be doing at the weekend...
Also tried Choicetree, but the interface for making the decision tree's was monumentally bad.

"You can enjoy the joys and wonder of Android without spending a fortune...!"
I now intend to see if this is true!
Thread Purpose:
Provide a discussion area for those of us who are financially impaired, like myself, but want to experience the joys and wonders that tablets and android might hold...
At the moment the thread may also touch on android on mini-tablets (which might also make calls...) and larger tablets (with keyboards...hdds...lcd monitors etc) simply because on a shoestring budget you have to make do with what you have.
I hope to explore ways in which you can use Android it in new and interesting ways without paying out massive amounts on expensive hardware.
I'm not sure if it is totally achievable or not, but I'm sure it will be interesting to find out what you can do for less compared to the expensive options which are out there.
Idea's, comments, thoughts, discussions are all welcome.
The more unusual and interesting the better!
Thread Structure:
This first post will provide an index and links to the main discussion points/topics on the thread.

Topic One : Show Me The Droid
Before you can do anything with Android, you probably want to see it!
This topic will outline various ways you can "get at the driod" without spending anything.
Method One: Using your existing laptop or PC
This was the first way I got to play with Android (a long while ago), and that is using an Android live CD. I used something similar to the live CD from http://www.android-x86.org/ (images taken from site), which allows you to boot your computer with Android.
You can burn the image on to a CD/DVD and boot it cleanly or you can use a virtual machine and boot within that.
With a little bit of legwork, and a compatible computer you can boot from a USB key so you can carry your droid with you.
You can even install it, even dual boot, if you are brave!
While this is a simple and very cheap option (at most it should cost a CD/DVD to burn on), there is one slight problem...most computers don’t have touch, gravity sensors etc etc!
You have a number of options if you are seriously wanting to use this more:
1. You can continue to use the mouse (at least they seem to have a cursor now!)
2. You could probably make use of a large touch-pad (can be expensive, but cheaper ones are around)
3. If you have a small screen you could try adding a touch screen (8-10” touch screen overlay can be quite cheap but you will need to install it yourself and that can be tricky and will risk damage).
Perhaps this method could be interesting to try out as a low cost GoogleTV platform, but there would need to be some work done regarding the control method. Someday I may look into this option in more detail...
Microsoft Kinect not been plugged into to android yet???
Anwser: Yes it has! Ok, shame I don’t have one.

Topic One : Show Me The Droid
Method Two: Using the android emulator (also on your existing laptop or PC)
Of course for the developers out there, there is always the Android emulator which comes as part of the Android development package. Each time Android update the SDK (software development kit) for the latest release of Android, the emulator is updated to run the newest version of Android (this is often the source of early ROMs).
This does allow you to play with the latest Android version as soon as it is out, so you can get a feel for what features are improved etc and you can try out different versions to get an idea about the differences between them. You don't even need to install anything more than the Android emulator SDK if you don't want to write any code, as you can run the emulator separately to the development environment.
However, not only does this have similar control issues (except maybe that you get “soft-buttons”) but it is quite slow even on a fast machine.
(Click Image For Larger Version)
The advantage of course is it opens up a whole world of development options. The google developer site provides instructions for getting set up. Once you’ve jumped through the hoops, you can try it out by having a go at the various tutorial applications.
(Click Image For Larger Version)
Again this is something I may look at in more detail another time (such as getting setup, exploring what you can do with it and perhaps some simple development steps).

Topic One : Show Me The Droid
Method Three: Using your existing phone
You might just have that elusive Android device already, you just don't know it yet!
Clearly this option will vary wildly on the type of device you have and how in-depth you are willing to go. I’ve not managed to find a full list of devices which do support running android but it is safe to say that the “list” is growing all the time.
For me, my Phone is a Windows Mobile Phone, the HTC Blackstone, it’s quite an old device (in relative terms) but it has a good screen (3.8", 480 x 800) and modest processor (528 MHz ARM 11).
Fortunately for me, the XDAndroid group support this device, so I was able to make use of one of the many Android builds on the forums. I’m not quite sure what the current status is of this project, it seems although device specific threads have stopped, there are Android builds going up to 2.2.3...which I’ve had working on my device.
For the blackstone, running android is fairly pain free, since you install the files to your sd-card and if things don’t work out, you just delete them. One key component I required, was ditching (swapping) my class-6 SD card for a slower one (yes, slower!), once I’d switched to a class-2 one, android was up and running nicely.
(Click Image For Larger Version)
However, don’t get too excited yet, as many of the builds will have features which don’t work yet, such as Bluetooth support, camera and in-call voice (you can spend a long time getting the right mix of files for your device to get all these working) and many 3D accelerated games won't work. A lot of progress is being made here (I’ll go into this in more detail another time). Some issues you can live with and some you can’t. Also, if your device (like mine) is not a total powerhouse then you can expect things to run at less than optimal speed. Overall, don’t expect to be replacing your OS with an all singing all dancing Android one this way, unless you have decent device to start with.
All is not lost! By using one of the many dual-boot apps (they simply show a splash screen as soon as possible on power up) allow you to quickly select between your normal Windows Mobile OS and the Android one.
i.e. Gen.Y DualBoot by yozgatg
(Click Image For Larger Version)
This means you can keep a build of Android (or several if you wish) on your SD card and have a play with Android from time to time.
Personally I think this is an excellent option, even if the results aren’t perfect and it’ll probably cost you a fair bit of time experimenting, but the results are totally worth it.
I might revisit this in more detail if people would like me to. Hopefully I can learn a little more about the internals of how it fits together and provide a post on that.
For HD2 users (and some other phones), who are just too spoilt for choice, they can also install Android to their NAND (internal memory). This means they can totally replace the Windows Mobile OS on their system with Android, and because the device is fast, it apparently runs well enough to do so.

Topic Two : A Low Cost Tablet
Part One: Justifying the purchase
First off, the most important bit for this topic, how much does it cost?
I managed to get (buy) it for $90 (£56), including free shipping (limited time special offer).
Note:
I would not recommend this tablet at it's "normal" price of $130, since there are other tablets in that price range which are clearly better.
However, for me, the lower price was key here.
To put it in perspective, the Samsung Tab 7 Inch was £500 here - or $800!
The specs:
Code:
Model: Haipad M701
CPU: Telechip Tcc8902, 800MHz (ARM11)
OS: Android 2.1
RAM: 256MB
ROM: 2GB
Screen: 7 Inch Resistive (800 x 480px)
Ext Ports:
9v Supply
3.5mm Audio
Mini Usb (OTG Host) - hopefully will support Mass Storage devices
HDMI
TF (MicroSDHC)
Size: 192 x 114 x 15mm
Weight: 330g
Extra Details:
Gravity Sensor
Android Market
Adobe Flash (not supported)
Camera 0.3Mp
Wifi 802.11 b/g
My thought process regarding the purchase is this:
1. I really want an Android tablet, I’ve been look at them for months (in fact probably just after the iPad came out). In all that time I’ve lusted after tablet after tablet, but each time it came down to the cost, and the fact that I simply did not have $200/$250/$300 laying around. Throughout that period the number of tablets available have ballooned, the capabilities and specs too. I found myself looking at the affordable tablets, and then looking at the next one up (hdmi), then the next one (10” screen) and then the next one (multi-touch), until I’d priced myself out of my purchase.
2. With the advent of the tegra chips and honeycomb, the price of admission has been bumped slightly (I’d say you are starting at $300 for a low end one (quality of the screen/touch is be compromised - Advent Vega)) - previous to that an A8 based tablet, such as the A81 for around $200-250 was a good deal. To be a serious contender for anything which comes after honeycomb (for the tablet branch), and gaming platform that is developing (of which Cordy is the thin end of the wedge), the power step provided by the Tegra family is a must.
3. Back when I first started looking at tablets, I was in fact considering a very similar device (the X10 and the G10, of which the Haipad M701 is fairly similar).
4. Aside from wanting to use the latest and greatest releases from Android and games etc, there is a need for more modest requirements to be met. Can a basic tablet do this, I intend to find out?
These "modest" potential uses would be:
A: Replace/supplement a poorly designed portable Toshiba DVD player for in-car use, which in my opinion was probably the worst product I’ve ever purchased (despite the quite promising spec sheet) - although obviously I may need to revise this status soon!
B: A Doodle pad, something which my phone gets commandeered for quite often by my off-spring. So a slightly larger screen would be useful for this.
C: Simple Web-browser, most of the time only a quick check on the web is needed, so this may be more helpful than firing up the laptop (which being a work one, dislikes my wifi and network most the time).
D: Music player, either from connected memory for in the car or perhaps from the network.
E: eReader, I’ve read a few books on the Blackstone’s 3.8" screen, so a larger screen would be helpful.
F: Require a device with camera and HDMI at minimum, since this will hopefully provide more options to experiment with (1st build of Android on the blackstone, didn’t have camera support which ruled out things like google goggles etc).
G: USB Host (mass storage), I am hoping that the device will allow me to use external storage devices via the usb, this would be very handy for dealing with camera pictures and videos etc.
H: USB Device keyboard support, I find it very annoying that the Blackstone has no h/w keys, this seriously limits what you can do with it (such as emulation programs etc) as there is no easy way to control things.
I: RS232 Support: Although I seriously doubt it, it would be really useful to get RS232 monitoring running on the device.
J: A development platform for writing android software on and to learn about android.
In Summary:
Overall, aside from the video/USB requirements, I hope that I am not being too ambitious for this device, but clearly I probably am. If/Once I get the device, I shall evaluate it against these requirements and also see what other uses I can put it to. I don’t expect the device to manage all of the uses above (particularly out-the-box), but hopefully it an fulfill at least some of them (even if it takes some custom firmware/modding or even some custom hardware to achieve this) I shall be happy.
For all I know, the tablet may well never turn up...and if it does it could be next to useless (i.e. next to that Toshiba DVD player...). As it happens, one review of a similar device was “expensive paper weight”, I’d estimate it about the weight of a medium sized cup of coffee (without the cup), so might be useful for when we get the fans out in the office this summer.
My purchase timeline:
Purchased tablet on 17th March (estimated delivery 10 working days).
Item shipped on 18th March (estimated shipping 15-20 days).
“Departure from outward office of exchange” 22nd March - Left the source country.
Received item 28th March!
Overall Delivery time: 11days (7 working days).
In return for the excellent shipping, I can say that the item was from PandaWill.
Out of the box review coming soon!

Thread has moved from "General" to it's new home in "Android Software and Hacking General". At first I didn't plan for it to be Android exclusive but as it turns out, it is, so hello to all on this thread.
I am very new to Android, so please be kind!
I hope this thread can be a beginners introduction of some kind, let me know if there are errors or if you would like more information on parts etc.
Regards.

Topic Two : A Low Cost Tablet
Part Two: Android From The Box
Packaged in a retail box:
(Click Image For Larger Version)
- Tablet (thankfully)
- 9volt 1.5Amp Output Power Supply (US plug)
- US to UK plug adaptor (a nice touch, clearly they take notice of the shipping address)
- 2x USB Cable (mini USB to USB male, short mini USB to USB female)
- Basic set of ear phones
- Product dimensions measure exactly as stated in the spec (I’d previously printed out picture of the screen to 1:1 scale based on the measurements).
Although I didn’t expect to get an HDMI cable, I didn’t expect the HDMI port to be a mini one, so it would have been helpful to have included one here (or at least an adaptor).
(Note: The USB car adaptor is not for it and did not come with it, but I thought it helps as a guide for size - it won’t charge by USB).
Charging:
(Click Image For Larger Version)
The first thing I did was to plug the tablet in for a charge, there are two reasons for this. Firstly to check that the power supply is functional and safe (i.e. does not over heat) and secondly for the battery.
If the battery is at a low level, you have to treat it carefully - particularly if was in storage (as it will gradually lose charge over time). Li-ion batteries if drained below their bottom limit, will “crash” their voltage, this causes a lot of damage to the battery and it may never recover fully (or in attempting to do so it may cause excess heat == bad news). You should always avoid switching any device on when the battery is in this state, so always charge just in case before trying to switch on (most electronics should refuse to turn on, but best not to count on it).
For this reason I was pleased to find that the battery was charged to approximately 60-80% (I guess) which is around the recommended storage/shipping level. Also the charger or tablet did not burst into flames, which was nice too!
Turned On:
Switching on the device, immediately the screen shows a colourful splash screen, then some linux penguin/mole, before displaying the normal android boot. Instantly I am pleased that the screen is working! I am also impressed that the screen quality, brightness and colour look quite good.
(Click Image For Larger Version)
60 Seconds later and Android has booted!
I would be interested to know if this is particularly fast or slow (my only comparison is booting the Blackstone Android from SD, which takes about 4 mins). For me, 1 min seems fast enough, certainly as fast as starting windows mobile. For normal use, the device can be put to sleep with the main ([]) button, which is instant on and off.
Screen was already calibrated, and the normal start-up wizard ran for Android.
Pre-Installed Software:
Aside from the standard stuff, you get ES File Explorer, Meridian Media Player, Skype (I’ve not tested that yet), SkyFire Browser, Aldiko eReader, QuickOffice, YouTube App and Android Market. The pre-installed Android Market worked fine, and I was downloading new apps in seconds. There are also some Chinese apps which I’ve not tried, but overall, there is everything to on there to get you started off and enough for you to use it directly out of the box.
Aside from some demo pictures and a video, there was also some video which I guess was taken when they tested the unit, it is a good sign that they appear to have taken the time to check the unit works, calibrate it, check things like the camera are functional etc (not sure if this was Pandawill or the manufacturer, but it was within an office so I suspect the former). At 0.3mp, the front facing camera clearly isn’t amazing, but in reasonable lighting it is good enough to see the subject in question quite clearly (one thing though is it is mirrored - guess for skype use (if that works)).
Out Of The Box Impression:
Overall initial impressions are, the screen appears to be pretty good for the money. Colours are slightly more washed out than a more expensive screen, but not overly so. The resistive touch screen does take a firm-ish touch to use, but again, not overly more than other resistive touch screens.
The size and weight of the unit appears to be nicely balanced, it is easy to hold in a single hand (for an adult) while using it with another (or thumb typing and holding either side). The outside bezel is just the right size that, if you need to, you can hold the edge with your thumb without touching the screen etc. The plastic housing, which is rigid and feels solid, makes the unit feel quite good quality. The piano black finish of the back (like a psp) does attract fingerprints however the screen itself doesn’t, which is great.
Although it was never going to be the fastest Android experience, however the unit does seem to keep up with the operating system fairly well, definitely fast enough to be usable.
The unit feels nice and appears to work well, so far excellent value for money.
Next time I shall evaluate the tablet against my requirements and see how it fares...

Topic Two : A Low Cost Tablet
Part Three: Passing the grade? (A-E)
Crunch time! How does the low cost tablet fare when lined up against my expectations and needs?
Meeting My Requirements:
A: Replacing A Portable DVD Player
Viewing photos, videos and listening to music from the pre-installed samples was easy and the units response was reasonable. There was good video playback of the 720p sample (I expect this was encoded to suit the device obviously), and the photo browser did a nice job of displaying and sorting through the photos. Sound was ok, by no means hi-fi standard but enough to listen to over moderate background noise (sound as good as the DVD player - but can’t really say this is hard). This will take a bit more investigation to determine what formats are supported and from where (local storage, microSD, flash stick, HDD, network, internet etc etc). However, even if videos need to specifically encoded as long as they can be played from a mass-storage device (or at a push the SD card), this should meet this requirement fine (did I mention the old DVD player is terrible...).
B: A Doodle Pad
It took no time at all for my offspring to try this, safe to say the unit passes this test with flying colours. One huge improvement is that the Blackstone touch sensitive call buttons etc were not in the way any more. Still to find the perfect app for this:
On Windows Mobile its My Note by MyLostBlog which is a good balance between clear interface and function (I still prefer 2.1 over 2.6).
(Click Image For Larger Version)
On the DS, Art Academy is favourite (although what it has in features, it lacks flexibility). Also Flip Note is worth a mention, I would love to find a similar app on Android.
Art Academy (art software) / Flipnote (animation program)
(Click Images For Larger Versions)
At the moment the star for Android is AutoDesk’s SketchBook Mobile (perhaps a little complex for younger children to fully do everything but easy enough for them to use and enjoy most of the features, excellent for adult use too!). AutoDesk’s app shows the quality that is possible with Android (although at the expense of lag free response on this particular device), I’m still very impressed and the 7 inch screen makes it all the more enjoyable.
C: Simple Web-browser
First off the lack of flash is annoying, but there is at least “some” flash support (I assume flash lite) from the Skyfire Browser, and even the google browser when it came across an embedded YouTube video it directed it to the YouTube app to play.
Browsing is reasonable, the wifi signal is probably below normal, but if you have a good signal, the browsing speed as comparable to my phone (for me the google browser appeared to be faster, but that might have been down to my wifi signal at the time). Here, multi-touch or at least the dual-touch of the later M701 models would be useful, as Pinch-to-zoom would be helpful. At least with the 7 inch screen the need to zoom in and out all the time is reduced (also I’m sure by experimenting with different browsers and settings the perfect balance will be achievable). It will never replace the desktop for web-browsing, but it is fine for quick searches etc.
Google Browser / Skyfire Browser
(Click Images For Larger Versions)
D: Music player
I’ll hold judgement on this until I find a more flexible app, since I had problems navigating around my music and playing it by folder unless it was on the SD card (I was only using some files I had available, I’m sure it is a lot simpler with correctly tagged albums). Once playing the music though, it managed ok (although it did experience issues if you attempted to “multi-task” and load apps etc while music was in the background - although that may have been the app I was using and/or fiddling around with the usb connections). The quality isn’t the best I’ve heard, but it is sufficient. I think overall, with the right app, the unit will perform this task without issue.
E: eReader
Just by trying the pre-installed Aldiko application, it is clear to see that this unit is great for reading. The text was very clear and easy to read with plenty of text visible and even on the smallest font setting (point 10) you can easily read without issue. The g-sensor rotates the screen as required (hopefully there is an option to turn it off - for reading while laying down [Yes, there is a setting for android generally]). The screen is slightly shiny so would suffer in direct sunlight, however it is reasonable for reading in average lighting. I also tested with a pdf, which displayed ok using QuickOffice, but features such as re-flow (available with Adobe’s reader) would definitely help to fit things on the screen.
[Update: Once I've installed Adobe reader, pdf's are very easy to read, although the lack of resuming where you left off means you have to keep track of page numbers yourself (this is no different to the Windows Mobile version).]

Thanks! I should be adding some more later on today.
I'm open for suggestions for topics etc.

Topic Two : A Low Cost Tablet
Part Four: Passing the grade? (Continued...F-J)
Meeting My Requirements (Continued...):
F: Camera & HDMI
As I previously mentioned the camera is not very good, but since it is front facing (it’s located to the right side of the ([]) button) it clearly is not suitable for taking snaps etc. Using google-goggles, the images are just about usable, but it appears the google-goggles app can’t take the pictures directly (you can import pictures which then allows you to take photos using the standard app and open them).
(Click Image For Larger Version)
[Android Logo taken with camera]
I’ve just tested the HDMI (I’ve managed to get a mini-HDMI cable) and after enabling the output via the settings page and restarting, the screen correctly displayed on the TV. Films and games do look good on the TV, although some adjustment to the alignment would be useful. Although you can output in either 1080p and 720p, the resolution is matched to the device 800x480 (although I might be wrong for direct video output), also from first impression, 1080p is lower colour depth than 720p output.
G: USB Host
Ideally the USB connection for host/OTG would be it’s own full size female usb socket (i.e. a normal USB socket) but instead you need to use the USB cable provided which converts the miniUSB to a USB socket. Tested with microSD card reader, flash memory stick (4Gb Kingston), the Blackstone (in mass-storage mode) and even 2.5 HDD which worked even without extra power (I was surprised at this as it is only a generic enclosure with a random laptop drive, however I did not try this with a low battery just in case that did damage). All of which appear under the /scsi/ directory. So far I’ve been unable to find how to “unmount” the drives (you can unmount the sd-card and the internal nand memory via the settings but not the OTG device), so when you disconnect you get “USB Device unexpectedly removed” message.
H: USB Device keyboard support
Using the same OTG cable, plugging in a keyboard was easy and seamless (it just works straight away). In fact, I tested this using a Logitech wireless Keyboard and Mouse and both worked perfectly (aside from the fact the keyboard is about 5 times the size of the tablet). I also tried another USB keyboard, which in the past I've noticed does not work when within DOS on a PC (where the Logitech does), this did not work, but I suspect this is simply the keyboard being slightly unusual. Keeping an eye out for a small and cheap keyboard now.
I: RS232 Support
I attempted this just out of interest but not really knowing what to look for can’t be sure it did anything. I don’t expect this to work without some serious work, but will see what can be achieved if anything. The reason for this is that many low level electronics projects can be controlled/monitored using RS232. In addition to this, I’ve also tried a bluetooth dongle (it has no bluetooth built in), and LAN adaptor, clearly they didn’t magically start working (no doubt the build does not have the correct drivers installed etc), but this is something I will look into.
J: A development platform
At a basic level, I can copy over built APK (android application) files and install them, even the ones which I had issues with on the Blackstone work fine on the device. Developing applications and working directly with the tablet is possible (will look at this in more detail another time), as a development device it is ideal.
The not so good...
Hardware Interfaces:
The single OTG mini usb port is annoying, it would be help to connect more than one device etc and not need to use an adaptor cable.
The mini HDMI, again would be good not to need a special cable for this (at least would have been useful to know ahead of time).
Buttons...no physical home or volume buttons, this does make things difficult sometimes (I believe there are software solutions for this, or options to re-map the keys).
Out-Of-Box mapping is: ([]) is power/screen key, right-side of rocker (with Home Icon) is the menu key, left-side of the rocker (with menu icon) is the back key! Once you get used it, it may be the best layout anyway, will need to experiment.
No Usb charging, from a pure ease of use point of view this would be very helpful, but most tablets don’t support this.
Sticking out of the SDHC card (puts the card at risk of snapping) - later version of this tablet this doesn’t stick out.
Obviously multitouch, bluetooth etc would be nice, but we know that.
The Grey Grey market:
This device “IS” a fake...Real Haipad vs. Fake
I can’t work out though if the unit functions any worse than a real one, all I know is, this one functions better than I was expecting and I’ve not found anything which the originals (if it is a fake) did which this doesn’t (so far).
I've now confirmed this with Pandawill, that the tablet is OEM, not a HaiPad original (at least they 'fessed up to it!). Considering it was sold as part of their own "Fight Against Internet Crime" promotion due to their recent DOS hack attack, it is a little naughty but as you can probably tell by now, I am still very happy with the device, no matter it's origin (but glad it was discounted). Also, the device does function as described by the specs, so other than the manufacturer the rest of the listing is accurate.
The only real issue is that new firmware will be a problem since I can't be sure if it will work or not.
Not all joy and perfection (I’d be mad to expect it):
Most applications appear to work, however, I’ve found that Angry Birds has issues with the surface texture graphics (the text which shows the menus/scores - a pain, but the rest of the game is playable). Apparently later versions such as Rio work fine, this just appears to be a feature of the telechip processor and does this for all HaiPad M701. Since I am not obsessed about Angry Birds (I can stop any-time I want, no really I can...) I can live with it. Also Raging Thunder 2 isn’t playable since I can’t see the menu blocks to select anything, I guess for the same issue.
Most games appear to work fine, such as Air Control, TurboFly 3D (lags sometimes, but not surprisingly since its full-on 3D graphics), Waveblaster (works very nicely, with G-sensor working), Pacific Wings (no g-sensor control). The G-Sensor doesn’t work on some games, but fortunately most have alternative options if that is the case.
It's a mixed bag for games, but fortunately I never intended games to be it's main use and I am quite happy with decent puzzle games etc anyway.
Overall - "A solution for now, but not the future":
The unit runs an ARM11 at 800MHz, with 256RAM, lets face it, it will never do all the graphical gymnastics that the Nvida Tegra 2 processors will perform and doing all but the very basics will probably leave it out-of-breath. Such a device is no laptop or even netbook replacement, but much like the iPod touch, it is a media player with many bonus features (& on a much better budget).
I’m sure as time passes (probably not long either) more and more applications will leave this type of low cost tablet behind, with the pace of processor development at the moment this should really be no surprise at all. But for now, the market is open and the apps are flowing, so I’ll sit back and enjoy them!

Topic Three: Low Level Basics
Part One: Oh ADB Debugger!
One of the first steps in getting properly connected to your devices innards is to ensure you are able to use the ADB (Android Debug Bridge).
The ADB is command-line terminal which allows you to directly control the device and file system of the device (or emulated device) from a PC or MAC.
On the face of it you might wonder why the ADB is of much use, the answer is that it allows a direct route to the entire file system as well as providing debug access directly on target as well as monitor log outputs as programs run. Overall it is similar to ActiveSync for windows mobile. Another reason to have this working is that if your device fails to boot, something messes up your system or say the touch-screen fails, you can use ADB to access everything on the device and also re-flash it. Also you will probably need ADB to root your device (more on that later).
There are a number of guides available for setting up ADB, so I won’t go into detail on them. Personally I followed Google’s own developers guide for setting up the Android SDK (Software Development Kit) since I also intend to write Android software and the ADB is part of that.
However, after a quick search, the following guide appears to cover most of the details.
The UnLocker - How To: SetUp ADB/USB Drivers for Android Devices.
For my device, the ADB driver needed some fiddling around with, since windows would not accept the driver was for my device [Editing the ini file and adding the VID and PID of the hardware didn't help me].
Eventually I found the following (following a tip from SlateDroid): The app PdaNet appears to supply suitable drivers.
I also recommend adding the location of ADB to your system path, so that you can call it from any command-line location.
Once the drivers are installed, check that when the device is connected (and debugging is enabled via settings) that typing “adb devices” from the command-line shows a device).
C:\> adb devices
List of devices attached
0123456789ABCDEF device

If you want to write software using Ecilpse you’ll also want to check that it can connect and deploy applications directly to the device for testing.
Within the Ecilpse, under the run menu select “Run Configurations...”, within the Target Tab, the “Deployment Target Selection Mode” must be set to “Manual”.
(Click Image For Larger Version)
This enables the “Android Device Chooser” to prompt when you attempt to run/debug from Ecilpse.
(Click Image For Larger Version)
Build and run your application or a test one and it should now run directly on your device.
There are also a number of GUI apps around which make use of ADB to provide easy ways to manage applications, transfer files etc all without needing to mount and unmount your sd cards to and from the device. At the moment I’ve started using DroidExplorer, even from initial impressions it is clear the features are quite extensive (you could probably write about 20 guides on how to use all of it correctly).

an excellent article overall.
question about the tablets: are most apps up-sized to fit the resolution, or are there a large variety of apps natively designed to run at the bigger resolution?

This is an interesting question!
Although my tablet is WVGA which is the same as the blackstone (so I can't test this directly!).
You'd need a much higher resolution device to go beyond the officially supported resolutions, (obviously Android 3.0 supports more).
From what I've read and from doing some app development, apps should scale to fit the screen (if programmed correctly). I've read that some apps don't scale for some tablets, what the root reason is for this, I wouldn't know, since the support is there in the API.
Basically, the android sdk provides various ways to describe the layout of your screens, and they encourage you to use ones which describe them in terms of proportional amounts (for the Linear Layout) or in terms of position of items i.e. to the left of item A (for Relative Layout) etc. The other layouts all work along the same lines, i.e. you don't worry about the size of the screen and calculate each position by hand like you do with windows mobile etc, it is all determined by the API.
You can see the different layouts code here and if you find the ApiDemo APK (I'll post if you like) you can view them. However, you can break all the rules and still use the Absolute Layout, where you return to the good old days of x,y co-ordinates. Even then you can use a values which are relative to the screen size and pixel pitch (see Difference of px, dp, dip and sp in android..) so there really is no reason to hard-code it.
As for graphics, I've not done this yet, but I know this handled if you use "9-patch" png files...they describe them here.
The idea here is that the black pixels around the edge allow the designer to say which bits are fixed size and which bits can be stretched to fit etc. It is a really tidy way to do it I think. Imagine how you'd have to do it otherwise if you created a button image with an icon on which would need to be resized to fit!
Oh, there are also provisions to provide low-res, med-res and high-res versions of the graphical resources, so again everything should scale nicely and look good without the need to scale everything all the time. There shouldn't be any need as such for "large" versions of apps, unless the developer wants to change how the app works by making use of the extra space or if they want ensure the "small" version takes up less space. I'm not sure how it determines which resource to use etc or if they all get installed etc, I've not looked into it.
So as long as the designer of the app has done all this correctly then it "should" scale correctly to whatever resolution. Of course, to claim this is true, they would need to test all resolutions. Fortunately you can manually create high-resolution emulated devices so it can be done but that is not the default.
[Now you mention it though, I shall ensure I test any apps I create at least once in high-resolution, it sounds like a good idea!]
I think this might have been why the retina display didn't make it to the iPad2, it would have required app developers to produce yet more app versions to deal with it and re-do the graphics yet again. Unfortunately I don't know anything about how iOS deals with these things, but you don't get the standard sized app in the middle of the screen or a x2 type option as you do with iPads.
Thanks for posting the question, hopefully it answers it (in theory anyway).

Topic Three: Low Level Basics
Part Two: The Root Of It All
I looked and looked for this information but I couldn't find the clear answers I wanted regarding rooting, so here is the info I was after.
What is ROOT, do I need it?
Rooting your device is not essential, for most the things you do with a tablet you will not need root access. Rooting is the process by which you enable “Root” access to the system’s low level files and hardware, this is achieved by enabling “super user” [Linux term for the highest level access which has higher level permissions to files than a normal user (like an Administrator)] access.
In most cases, apps will access hardware and files through the Android API, but in some cases they may need better control of the hardware than the API allows or access to files which are normally locked.
For this reason these applications require “root” access, typically apps which take screenshots (I assume to allow access to the screen data) and backup programs (I expect to allow access to all your files) are such programs.
Am I Rooted?
One thing I had trouble working out was working out if the device was rooted already or not. The quickest way to find out is to try to use an app which requires root access, if you device isn’t rooted it will tell you.
A good way is to download “Terminal Emulator” from the market (or direct from the author) . Then type: su which stands for Super User! (if your device is correctly rooted the “$” will change to “#” (ideally it will also prompt you for permission to enter superuser mode first - see SuperUser.apk below)).
Other signs you are rooted is to look for the “su” file in /system/bin/ but this will not confirm if the file is set to be executable correctly or in some cases different names are used to make it harder for unwanted apps to locate it.
Can I break/brick my device by ROOTING?
Actually ROOTING the device shouldn’t really cause any problems (since all you are really doing is installing a file which allows you to grant “Superuser” access). However, since ROOTING (by definition) allows entering into “Superuser” mode, this mode does allow you make much more serious changes to the system than you would in a “Normal User” mode (which is the whole point!), so clearly there are some risks involved while in this mode (and you may want to consider how this fits with your warranty). If your device isn’t open, then I suspect the main risk is getting your device into an unlocked state so that you can perform the root process first (since my tablet was not locked in anyway, I don’t know about this aspect).
Once ROOTING is complete, you don’t remain as a “Superuser” but any application is able to use it if they require. For this reason, the Superuser.apk application is typically installed, which detects when a request for “superuser” permissions are made and allows you to accept or reject the request.
The ROOTING process itself is reversible, which you may wish to do if you need to return your device for repairs etc.
How to root?
There are many guides and methods, but I shall take one specific to my tablet (posted by OffWorld on androidtablets.net) and explain each step in detail, since none I found explain what it is you are doing.
First you need to get the latest su and superuser.apk files from here.
Now, connecting the device to your pc, open a command prompt and type:
adb devices
Adb will respond hopefully with your list of devices:
List of devices attached
0123456789ABCDEF device
This confirms your device is attached and adb is able to communicate correctly.
Command 1:
adb shell mount -o remount,rw /dev/block/mtdblock3 /system
This runs adb (the terminal program to your device) and mounts the specified folders with read/write access.
Command 2:
adb push su /system/bin/
This sends the “su” program to the location on the device (note this assumes have the “su” in the same directory as you are running adb from). You can confirm this by navigating to the location on your tablet and see that the file has been transferred.
Command 3:
adb shell chmod 4755 /system/bin/su
This changes the permissions of the “su” file you’ve just transferred [details about chmod].
By using the command: adb shell ls -l /system/bin/su you can see the permissions.
We’ve changed the permissions from -rw-rw-rw- to -rwsr-xr-x, this allows the file to be executed.
Command 4:
adb push Superuser.apk /system/app/
This installs the Superuser.apk package on the device. This is important since this app allows you to control superuser access, rather than just allowing any program to obtain “superuser” rights.
Command 5:
adb shell reboot
Restarts the device.
Following this process, you will have the SuperUser application installed and applications will request Superuser access if they require it.
Note:
You may find for screen capture programs you need to allow permissions automatically or you may only end up with screenshots of the permission screen! Yes that's how I got the above one...

Excellent topic ! i've got the same pad and was wondering if you did find out a good way to completely backup the firmware. I've used Titanium but that's not a complete dump.

Welcome to Xda!
That was going to be my next topic.
I've just been focusing on my WM development stuff at the moment (new RSSTab in the works), but will return to the tablet after I am done.
I'm not quite sure the best way to back it up yet, I was planning on trying out the ClockMod route, trouble is I'm quite new to it, so a little cautious about doing it before holidays.
I hope to try out some low level interfacing using the usb at some point too, as I've got a development board to play with.

Side Topic: The Future! Quad core and beyond
This time next year, Rodney...
Just saw this, and thought I would share here!
ASUS planning quad-core Tegra 3 tablet
See the two videos which are on the linked page...
Yes that is 2560x1600 resolution, hopefully to go into a 10" retina display.
Simply said, the future of these chips look rather interesting to say the least (no doubt are related to Sony's NGP).
Looking at the video, what we will be able to do with mobile devices will be rather impressive. Combine that with the new touch and perhaps kinect type control technologies as well as improvements with battery capacity/recharge tech, improved clear & colourful screens and things are shaping up nicely.
Boy are we going to have some fun hacking the innards out of them!
It is easy to see that for me, I've made the right choice by not spending lots of money on an impressive and expensive tablet at the moment. Since I'm happy to wait for a better tablet and until then I can have fun playing with my basic one.
Let just hope that the manufactures come up with a decent device, that is able to be hacked and perhaps might even be half decent out-of-the-box.
What is next? Who knows!
It's interesting really since I think that phones are quite close to the point where they have about as much processing power as they need** (perhaps with the exception of ones which include extra connectivity to HDMI/pico projector, keyboards etc). When they are subjected to the confines of a 3.8"/4" screen, you start to hit the limits of usability rather than processing power. Tablets have given the hardware room to stretch it's legs a little and show us what it can do!
**I'm not saying they won't need more in future, but I think perhaps an upgrade won't be as essential or spectacular, as it once was, until they evolve to the next form of course. I suppose the ultimate progression though is the usability of something like a tablet or pc but packaged in the form of a phone or smaller device in some form or another.
The software needs to catch up now though, we need better multi-core programming techniques, far far better privacy protection, and better stability overall. Thankfully hardware gives us the grunt to do this, it just needs to develop and improve to the point where coding can be done at the highest level of abstraction (which allows time to be spent on creative aspects rather than low level code details).
If you want to look even further, the prospect of re-programmable hardware is getting closer. This is where all the single purpose chips (such as video decoders) are replaced/supplemented by ones which can be re-programmed. Not only does this allow for codecs etc to be updated while still keeping the advantage of hardware decoding/coding (i.e. realtime without loading the main processor or drawing lots of power), but some applications could in-theory call in dedicated processing for specific tasks allowing for some amazing performance when performing complex and processor intensive tasks.
Fun times are a-coming!
Bright things are ahead for our fondle blocks, I don't even care too much if they are android or ipad or something else, as long as we can buy it (without selling a leg or two - ok, not iPad then!), program it, play with it and push it to it's limits and beyond!

Side Topic: Multi-Touch Technology - with No Touch Screen!
ZeroTouch 'optical multi-touch force field' makes a touchscreen out of just about anything
I wonder how much this costs to produce, quite a nice solution and ideal as a add-on to current screens. Depending of the cost of each infra-red and LED module it hopefully won't be too much. Imagine getting it fitted to your coffee table at home!

[Q] Designing new Tablet, could use some experts feedback!

Hello,
I am an Industrial designer and part of implementing a product is some good groundwork. Therefor i am doing research regarding functionalities of current tablets and user needs,
I am hoping to get some inside information on XDA from some veteran tableteers. I consider you guys as early adopters and that is excactly what my target group is
I am working for a client who which uses the keywords; simplify, iconic, bold, rebels. There current portfolio consists of a phone with only one function; calling. The phone is therefor cheap, but it also make a statement 'look how cool i am with this simple phone'.
I want to design the next product for that company, in my case a tablet. To fit the current product portfolio the tablet needs to be as iconic as the phone. So simplifing everything to the basic needs of users, therefor it also makes a statement.
Products which are currently 'on the market' which are some inspiration for me are;
Wacom inkling
Sorry cant post links yet..
Noteslate(not yet on the market)
Sorry cant post links yet..
Boogie board
Sorry cant post links yet..
Part of being iconic and making a statement in my POV is bringing back the blackboard feeling with the squeeky finger due to the chalk. Combining the 'paper feel' with electronics; this is also what the company prefers.
first mock-up(excuse me for the quality)
Sorry cant post links yet..
I think the main feature of this tablet will be notetaking and drawing, including a mail service and maby an agenda. You can add or subtract functions. The focus will therefor be in the business market and perhaps for in class during lectures.
One focus lays on personalizing the tablet. Like you would do know with your paper notebook, making drawings and it feels yours. Where tablets know are being handled with care you are not personally bonding with the device. I am thinking of features where you can add your own gestures for turning on the device (like your autograph) and drawing an envelop around something will automatticaly mail it.
Finally my first questions for you guys (im hoping to asking more in the future);
1. Which functions do you use most on current tablets
2. Will you buy a tablet with these limited amount of functions, and what would you pay
3. If you own an tablet, would you see yourself using it as an personal agenda and notetaker, why and why not?
4. Do you see the monochrone screen as a negative or positive, why would you prefer a colour screen (if outcome was negative)
5. How do you currently personalize a) your tablet and b) your notebook/agenda/phone etc. Outside and inside
6. what size would you prefer?
Any feedback will be welcome, also criticism (constructive) is very welcome.
I am currently just in the research stage, but chances are this product actually hitting the market.
Thanks very much in advance for your time, im hoping for some great feedback!
greets, Kars Rotteveel

Android Smart Ring - A Step Beyond Possibilities

Production of this Android Smart Ring can start soon as soon as some Big Device manufacturer lays his eyes on this ( I mean when he/she gets to know about this project ). Hopefully Google should be attracted towards this
The Android Smart Ring is an inspired device from smart-watches but has an unique Design,Specifications and can do beyond possibilities.
Watch Video HERE
I am an College Student who got this project Idea. I just want to give this project a Go and see if I can make it a success. I wanna give people a whole new experience of Technology. It's a unique Idea which has never been done, if previously it's done then that must be not as good as this one. The Android Smart Ring features a curved 720p display, Bluetooth v4.0, NFC, High Clarity Speakers, Microphone, powered by 1GHz processor, 512MB RAM, couple of required sensors, has Transistors (acting as a battery which requires no charging) and this ring runs on Android KitKat (or) Android Wear (in near future).
Keep Sharing this Idea and let each and every men know about it. Help me making this Idea an reality Thanks for all your support in advance.

I don't think I understand how you intend to incorporate a 720 P display on a small ring along with a whole bunch of other hardware
I don't think we have hardware capabilities to make your idea feasible at this point

What this dude says is true. It's only possible if you created a time travelling machine and travel to the future and retrieve the techology from there, now this is definitely a viable and possible option for you homie.

Okay.. Wait a min. So, you guys think that this isn't possible. Let me tell you one thing, you must have heard about Phonebloks, right ? Was it possible back then ? Hell no, now Google has taken the project and made it possible. So, nothing is impossible

I would think scale down what you are expecting out of it, maybe not 720P display. Start small, and work your way up. See if you can get a working prototype first even with a basic display that might be small, because 720P is quite a big ask for what I would imagine to be a very small device.
Analyse it from every possible angle and lens you can think of. Here are some examples to start you off: Technical ability of construction, marketing, corporate usage, end user.
Here are some examples:
Technical:
Start trying to see if you can get electronic components small enough to even complete something like this first. If you can, what's the limit available today? Maybe you can't get a speaker small enough, so you work around not having that. Work out where your limits are.
Then let's say with marketing: Who are you trying to sell it to? How can you convince them to buy it? Does it provide any perceived value (not necessarily actual value), or will people see it as an expensive paperweight?
Corporate usage: Could you display advertisements on it without being too intrusive from general functions? Could it be used in a corporate setting, add any value to business running?
End user: Will it be comfortable and easy to use throughout every phase including charging, or would it overheat and cause discomfort? Will it last? Can it be adjusted to suit the needs of people (e.g. different finger sizes).
Give this a thought, and work out if you can provide solutions to every aspect, and identify potential problems BEFORE you even hit the market. You wouldn't want to go through extreme difficulty to process and manufacture it, and in the end it flops badly because of overpriced/poor quality, or maybe simply nobody wants one.

Well, I haven't just though about the production and all because I ain't ready to do that, I just provided a concept (or) an Idea and asked people to share it if they liked it and then maybe in the future a company might notice this Idea and bring it to reality. I never thought of bringing this thing to production by myself (coz I ain't a rich guy). Speaking of the speaker, it can be replaced with vibration alert which will be more effective (it can be annoying too) for people to never miss an message alert (or) call alert or whatever notifications you get.
When talking about marketing and corporate usage, well there's always a way to target everyone around you for it. However, it just requires an simple yet effective Idea to present in front of the public and it won't be expensive (deduction of specs to low-end ones would help).
Of course, it will be comfortable and easy to use. It's just same as your usual ring replaced by this Tech things from which you can see what's going on your device without a need to take a look at it by taking out it from your pocket. It's just a device which shows you alerts about your notifications and allows you to send messages directly to your colleague by using microphone (voice messaging service).
I Hope you are satisfied. Feel free to ask more questions, I am happy to assist you and NOTE :- It's just and Idea which I haven't thought to bring in production by myself.

Just the part about a small 720p curved display, it can be done for sure but at the cost thats can scale into production? I don't think so! if it was Samsung would already make this kind of device
sent from Carina Nebula with my Nexus 5 inter dimensional cruiser...

I think you need to do some searching and find out for yourself that current technology is not there yet.
Google some of the components you're saying will be in the devices, then look at the smallest ones available. It's just not going to work.
Transistors? They won't be large enough to drive the hardware, if you can find them that will fit in a ring.
720p screen? Why? It's on a ring. Anything at that resolution is going to be UNBELIEVABLY SMALL.
High Clarity speakers? Aside from being extremely vague, you show that you have no idea how this technology works. Get some bose earbuds. Their quality is great. Then again, look how big they are. If they could make them smaller, they would. Hell, even hearing aids aren't that small, and their quality is acceptable at best.
1ghz cpu? Find me a 1ghz ARM cpu at this size. They're not available yet. The manufacturing process just isn't available.
512mb ram? Again. The chips aren't going to fit.
Maybe you can get some of these things into a ring, but definitely not all of them. The technology just isn't there yet. I don't mean to discourage you from your goal, but you really just need to be smart about it. Patent your idea, and keep your eyes and ears on the tech world. Be realistic. When the technology is available, you can bring your product to market.

Recomended apps for small screen Android phones, including PVG100

Hello,
I don't (yet ?) own a PVG100. Therefore, I cannot help with PVG100 hacking.
But I may be of some help nonetheless : I have been (and am still) using a tiny Android phone (Sony-Ericsson Xperia Active, 3 inch screen) for 8 years.
I want to share the best apps I found for small screen Android phones, including PVG100. And I am sure that other folks have good apps to share too !
Please share here !

First, an application that is a must have on all tiny phones. I wouldn't buy a tiny phone that cannot run it.
MessagEase is a VERY different keyboard.
Instead of a myriad of tiny QWERTY keys, it features a small number of big keys.
It is like a numeric keypad, but every key has multiple uses. It depends if you tap it or swipe it or tap-and-hold it.
It takes a few days to get used to it, but when you feel comfortable with it, you wonder how you could use your phone without it.
Try it. Don't drop it after 5 minutes. You will be rewarded.
You can customize letter (and special characters) placement, color, appearance and the size of the keys.
Exideas (the editor of MessagEase) even provides key placements (and word dictionaries) optimized for various languages.
It has a drawback, though : the suggested words are not always the ones you would think of (at least in french). But since you don't make as many typos as with a QWERTY keyboard, suggestions are not as important.

Second, a fully customizable application dedicated to sports (not only biking).
With IpBike, you can select what parameters you want to display, and choose size and placement.
I use it a lot with my phone GPS and an ANT+ heart rate sensor when I hike or run or skate, and with ANT+ cadence & speed sensors on bikes.
If the PVG100 is not ANT+ capable, IpBike is also compatible with Bluetooth sensors.
You can display a map (and follow a GPX trace), record your trip, read graphs on your phone. It is very complete.
Its drawback is that, past 2000 km, you must buy IpBikeKey, a Key program to unlock IpBike.
A small, light and waterproof phone like the PVG100 is well suited for activity monitoring. IpBike is well suited for small (and big) phones.
