I've tried and tried to get a number of questions answered here and on the Cyanogenmod forum, but either my questions are extremely advanced and esoteric, or everyone here is just users and developers are somewhere else.
So I'm creating this thread of Mysteries To Science, for all those questions you have which no one is able to answer. I've run Debian exclusively for 14 years and am used to having total control, and the lack of knowledge on Android here is perplexing. I have the Nexus One, but I think these questions apply to essentially all Android phones.
Here are my Mysteries:
Messaging Problem - I use ChompSMS. A couple weeks ago I stopped receiving text messages, about the time I removed the stock Messaging app using Titanium. I can send just fine, but I never receive them.
Anyone seen this problem? Does Chomp use its own system, or does it depend on Messaging? I reinstalled GApps thinking Messaging is there, but it's not. Is it a dependency, and if so where is it? If not, why do I no longer receive and what can I do about it?
App Shortcuts - I created a desktop direct messaging shortcut to call my boss, with a pic of an angry boxer dog. Made the pic as a gif and png with transparent background, although it is ending up as black on the desktop for some reason.
I assigned the pic as the shortcut's icon using Gallery, and I suspect that Gallery is converting the background to black, but I cannot find where app pics are stored either on the SD or /system.
App Sorting - Also like so many others, I have many many apps. I have always categorized my apps, since I started using Debian exclusively 14 years ago. To have all my apps dumped into a giant pile as they are in the N1, is irritating. I installed Apps Organizer, but it seems to want me to tag each app with a category, rather than basically making folders with categories such as Utilities, System, Multimedia, etc.
Is there any way to make folders for the apps?
Calendars - I am not sharing my personal information with That-Search-Engine-Everyone-Uses. (Yes, I've deinstalled all GApps except Market, and use exclusively AppBrain's app to install apps, but still haven't found a way to buy apps in a way I trust) Can anyone recommend a calendar app which is compatible with Linux and M$ calendars, yet doesn't sync with some Outside Authority?
Compass - The magnetometer in this phone is completely unreliable in my experience. Any stray magnetic field throws it off by 18 degrees permanently. The only way I've found to almost calibrate it is with the Compass app Calibrate function, but to run that before any other app which requires a compass is a headache. Is there something I'm doing wrong?
SD Card - What relation does the SD card have to the system? Why is it that when I install an app to the SD card, its widget is no longer available and its daemon will not run? Is there some way to add the SD card to the kernel's awareness for these purposes?
Factory Reset - If I back up system and apps using Titanium, and desktop and ADW settings using ADW, and export contacts, is that enough?
What are the data structures in Android? I know there's the kernel, and ADW is the full user interface, but where are contacts stored? Where are apps, /system/apps?, and if so where are their config files? Where are the desktops configured, and where are the shortcuts+icons stored? I can't find any such config files, and the only one I know of is the central system config file /system/build.prop.
How to recover my contacts? Apps installed in phone memory? Would a restore, restore whatever is ostensibly messing up the compass?
So given wherever these data structures are, what effect does a factory reset have? Exactly which data structures does it wipe/replace?

Android seems to boot from ROM before the SD card, once the OS is up and running then it starts to mount the SD card, so any widgets you have installed on homescreens while residing on the SD card won't load when first booting. You need to keep all of your widgets on the phones internal memory to stop this problem recurring. If you are having memory shortages you might want to consider using ROM Manager, partitioning your SD card and using an A2SD (App to SD Card) ROM that will install apps to the SD card instead of internal memory.
App Shortcuts - I created a desktop direct messaging shortcut to call my boss, with a pic of an angry boxer dog. Made the pic as a gif and png with transparent background, although it is ending up as black on the desktop for some reason.

I use Gallery in conjunction with Launcher Pro to display my custom dock icons it works just fine. It sounds to me like you're not making one of the layers transparent before saving it as a PNG.

Ya, it -only- boots from the 'ROM' (firmware). Need to keep thos apps that have widgets and daemons installed on the phone, or else they won't work. This is what I'm saying. Am using A2SD as it's built-in to CM6, so must move those apps with widgets and daemons back to the phone. None of this addresses why the system can't load a widget from the SD after boot, nor whether there's a way to tell the kernel about SD widgets.

Examining the images in Linux viewers shows the transparency. (checkerboard background) Viewing it in Gallery does not. gif and png both support transparent background, but it appears to me that Gallery does not.

I suggest you break down the Mms.apk and look in there. It does have dependencies, they're written into a file inside the apk telling it where to send the message and where to check for messages. It also contains the user agent information. If you could some how pack that into chomp or another mms/sms app then you might be able to delete the stock app and push/install your choice messaging app to the system.
You no longer get messages (I assume) because when you're sent an sms/mms it sits on your carriers server while it sends a message to your phone (you don't see it) telling it that there's a message waiting to be retrieved. It's expecting a certain response about the phones state and type. If the format is incorrect or it doesn't get a response then the message just sits on the server. To send a message I believe it just uses apn settings to contact the server with 'wait for message' then the server responds 'ready' the phone sends it and all is well. It doesn't request the phones state and type and therefor the lack of a UA has no effect. Of course that's my understanding of how it works but I could be a little off here or there
Thanks KCRic. I did a factory reset and installed CM6.1-RC1, and now I'm getting texts. I find that this has happened to others too. I expected to get an avalanche of texts when I factory reset, but nothing. At least I'm receiving them now.
I'm surprised to read that files are actually modified on-the-fly inside apk's. This would explain alot of things. Is there a way to manually modify those files using some sort of apk tool?

If you are using adw you can set up groups in the app drawer. Not quite the same as folders but pretty useful

Have you tried my backuppro for backing up your contacts and apps. There is a free version that will work for 30days. I personally never restore anything with TB, as it causes me no end of headaches. I use my backup pro to backup my personal data, ( contacts, sms, mms, dictionary, calendar etc ) I use applist to save a txt file with a list of apps i have installed. Then just reinstall the apps via market or diect push. This is just my personal o
I do this on a fairly regular basis ( trying different roms ) and can do it about 15mins
I have recently purchased a Samsung Galaxy S2. I have the phone set up the way i like it but i wish to try different OS versions which will require rooting and wiping my phone so a few questions regarding backups:
1) Currently i have my gmail contacts and facebook contacts "linked" together. I believe this is only stored locally on my phone. Is there a way i can save all this contact info so when i log back in to my profile in the future it will all be seamlessly placed as it was.
2) Currently i have a whole batch of homescreens with icons and widgets and my applications screen with every app in a "folder" can i back these up exactly as they are?
3) Within various different applications there are different options or save games and various things like that, are these easily accessible and able to be backed up
4) Finally can i just do an "image" of my phone and if i wipe it and mess about then simply restore that image back to exactly how it was?
Cheers for any help
boxrick,
Can't answer specifically for the Galaxy S2 as I don't have it, and because Android is "pimped" in various ways by different device makers some of the homescreens/layouts are custom implemented, and best backed up by the methods appropriate for--or offered by--that device.
Having said that, if you are using Google market, a lot of stuff (like the apps obviously) is automatically saved with them. Or the apps themselves can be backed up with any good file manager, like Astro, to an SD card or via USB.
I can't answer you about the Gmail & Facebook contacts being "linked together", but from experience most items are stored in the Google Contacts data-fields and stored remotely in your Google account (and therefore restored from there straightaway)
I have multiple Android devices, and to tell you the truth I pretty much just copy everything "en-masse" to a hard drive. If you're rooted, it's fairly easy to pull down almost everything this way. You're just dealing with files and folders, just like on your regular computer (which is why I'm pretty much done with anything "black-box" like formerly iphone/ipad, btw )
If you're looking for a "set-it-and-forget-it" type app, I don't currently use any, but on my travels I've seen a few "names" tossed around with good reviews. You can research
MyBackup Pro
Sprite Backup
Those two are pretty well known full-blown-backup type apps. They're paid apps, but cheap.
I've heard of The Missing Sync which takes a different approach by syncing all your data to a Windows or Mac desktop for backup and also for re-distribution to other devices. Sort of like a "data-centralizer" type approach, which might be up your alley. I think the app runs about $40 though.
Finally, I do use the free LifeSaver 2 app for important SMS messages and call logs-- picked it up over at F-droid.org. It's for pretty specific data types, but it's this stuff that usually is the hardest to save (since I don't actually know where it is when I backup the entire root directory + subs & files).
Hope the above gives you some ideas. My general advice would be to research, read the boards, with special attention to the threads dedicated to the Galaxy S2, because the other users have gone before you
And btw, if you find something really cool (including if one of the apps above turn out to help you), make sure you come back and post your findings. I'm always on the lookout for a "gem" app that makes my life easier.
Good luck!
Apps: Titanium.
Data: MyBackup.
MyBackup does a much better job at saving your contacts than Google does. MyBackup restores them exactly as they were, Google often loses custom fields and messes up your contact names. Just look at the mess when you sync a contact called "Al's Pizza (open 'till midnight)" back from Google. It also gets the timestamps on SMSs right, which most competitors don't.
You could forget about Tit and backup your apps with MyB too, but then you miss out on all the different batch jobs that come with Tit.
There's one thing that all backup apps choke on: widgets. I always have to set 'em up again after a wipe/restore job.
Can't titanium backup both apps & data?
Titanium can backup user data, sort of.
Restoring user data with Tit is not as straightforward as with MyB. They should add a user data screen so you don't have to hunt for your data in a long list of apps.
One final question, if I was to change from Android Phone A to Android Phone B. Will these "apps" and backups be able to restored to a totally different phone?

rogier, what widget app do you use? I use Elixir, and in it there's an option to export widget data. Search for the "edit widgets" button, click it and you'll be taken to a pane where all the widgets are replaceable. Below it, you'll see a "More" button--that's where the import/export widgets button is. After you export widgets settings (you have to type in a name for it), Elixir then saves that exact config. After flashing a ROM and restoring via Ti, you can then choose to add back your widgets via the "Import" button. Remember though: if you want to bring back a 5x5 widget, you have to choose "5x5" widget after long pressing on a blank space, otherwise the widget won't restore properly. With this, you can have as many widgets you want and not worry about the tedious process of reconstructing them after a restore.
do you have to use the paid for version of titanium?

Yes, you can with Google . Go to Settings --> Privacy --> Back up my data.
When you buy your new phone, select restore my data. At first you won't see any difference, but after a few hours your apps will be restored

Right now I've got Widgetsoid, DroidStats, Smooth Calendar, PlayerPro, DroidWall, Make Your Own Clock, and seNotes on my home screens.
Some widget apps have a backup option, some only come in one flavor (like DroidWall) so they don't really need a backup option. But others (like most notes widgets) don't have any backup option at all.
This is really annoying for the sticky notes widgets, because it's often impossible to remember what info you'd have to put back in them (which is why you wrote it in a note to begin with).
So I'd really like a one click option to back up and restore all my widgets.

Nope, you don't. The free version backs up everything too. It just takes more clicks to restore your stuff.
The free version of MyBackup only restores to the same phone that it backed up, so if you want to use MyBackup to transfer your data to a new phone you'll need the paid version.
I have purchased MybackupPro. The problem is I am fairly confident it will not back up my linked contacts. Therefore I need to root my phone and use TI backup...
Id like to post here http://forum.xda-developers.com/showthread.php?t=1125414&page=12 and find out about after unrooting, flashing back to the default kernel ( for warranty purposes ). Need 10 posts
Now it seems I am getting restrictions on the amount of times I am posting. This also doesn't help me much!
Having some spare time in Christmas holidays and after having used and experimented with my GNote 10.1 for about 3 months I thought about making some clean up and streamlining with all the apps I've tried and tested till now.
I've found that I've about 160 apps (of which about 50 apps can be considered as default apps already present in the pristine tablet).
Many are duplicate or alternatives for some "ideal" (but yet "non-fully satisfactory") apps...
I mean... I've 6 different file manager apps, 4 drawing apps, 12 note taking apps, 6 office apps and so on.
I think I'll keep many of them (even if duplicates of each other) for some time until I can judge what is better and what's not, to choose the best ones for my needs and also to see if the developers are making progresses (or if the app's development has practically stopped).
To understand better what I have and what I might choose or discard for each activity (note taking, office etc.) I've made a categorization in Excel (in my PC).
But I thought also there could be some (meta) app to organize and categorize apps inside the tablet itself.
After some search I think that Auto App Organizer could be the one.
It allows to categorize all apps and to navigate to them by browsing the categories. I think this could be much better and more convenient than creating category folders through the launcher.
Does anyone use it? Is there any other advisable alternative?
So, I thought we could make a thread for what apps you find most useful, that let you accomplish the most throughout your day..
Apps which help you with your workflow from Work to Home
Apps that would make you feel hindered, slowed-down, or less productive if you didnt have them
Apps without which you'd feel you'd have alot more work to do, or have less hours in your day to get things done
Whether you're a Traditional Artist, a Digital Artist, a Graphic Artist, a Fashion Designer, an Interior Designer, an Architect, a DB Engineer, an IT administrator, a Program Developer, if you're in Marketing or Advertising, if you're a Business Owner, a Company Manager, Office Staff, a Landscaper, a Florist, or whatever job you have.. Please share the apps you find most helpful
It could include anything from your favorite Graphics or Sketch program, a Calendar or Contacts Manager, a Daily Planner, a Financial Management Program, a Employee Scheduling program, a useful Programmer's notepad, or anything else you'd like to contribute
This also includes apps which you feel make your Android itself a more effective & Efficient device, such as task managers, button manager, switchers, or you own app workflows, or anything else..
This is an attempt to compile a list of the most useful Android Apps out there, Free or Paid, that other people could try out, or that you think might help other people increase their own productivity throughout the day or week, using their Android Device
I think we could all use better time management and a bit more free time in our lives

Seems nice, but, why didn't you start?

Heh.. I'm still looking for some
I currently use ES File Explorer for all my cross-platform File Browsing & File Transferring needs
& I use ES Task Manager for my Task Management.. u know, I've rooted my device, and I've tried alot of task & memory managers, but have yet to find something to tell me whats talking up memory when I get some malicious program that zeros out my memory until restart.. or suddenly occupies hundreds of MB which mystically goes unaccounted for.. I just feel there is still so much going on in my phone I have no control of and i havent found any solid program to give me that control
I use Adblock Plus, but it only works through a proxy, which stops me from seeing things through my Firefox browser... I still havent found a reliable way to block all ads. lets be honest, alot of those freeware apps wouldnt ever be bought even if they only had no ad paid versions.. it seems everything has ads now... and this isnt going to fix it
I use Floating Stickies for cross-app data transfer
I use Screen Off & Lock to conserve battery power & buttons
I use Swapps for fast app switching...Its great, but I'm still searching for something a bit better
I use Hackers Keyboard from Swapps just to switch between one of about 10 inputs I use
Touchpal X is currently my keyboard of choice.. but I dont like how it doesnt suggest most frequently used words.. and I.m not getting a full 26key keyboard for Pinyin either.. I'm currently talking to the devs about that.
I currently use Screenshot Ultimate, but still would like something with area capture, and expandable multi-line textboxes
I use Image Search for finding quick Photos to throw onto my social networking apps, mainly WeChat
and I use Floating Soft Keys for quick navigation, but I wish it would have an option to swipe to disappear off screen
but I'm still looking for a program which displays available memory, includes a list of running apps, end app & minimize app functions (i dont want android managing which apps to leave open or end).. with options to delete Cache of programs on end... also can free RAM, even from malicious programs that suddenly swallow over 200mb... and can let me add my favorite app buttons..
and I'm thinking of purchasing Softmaker for an Office suite, though it lacks Macro functionality and Wildcards in Find & Replace
I currently dont have many other programs, like calendar, time managment, etc.. I sorta recently moved from WinMo to Android. and I'm missing alot of my old WinMo apps to be honest.
-- Maybe a good question for me might be, what apps make you feel you have as much power & control as you had on WinMo, for the oldtimers here

There are existing threads for this sort of discussion:
[Discussion] Discuss your favorite app, tweak, widget, etc. (Least favorite OK too!)
[23.apr.2013] *COLLECTION OF THE BEST APP/GAMES FOR ANDROID* 165 apps - 200 games!!!
I ran a quick search and haven't seen this mentioned anywhere else yet, so sharing this info here for Mac users.
I just downloaded and fired up a free app (SmartFinder for Android) from the Mac App Store...looks to have come out just a week or two ago. Appears VERY promising, at least as an alternative to the rudimentary Android File Transfer that we've been stuck with for years. Seems quick and provides a proper classification and grouping of files (e.g., Pictures, Video, Music, Files), which can actually all be opened directly from within the app (unlike with AFT). Should make things a lot easier and just all-around more enjoyable compared to what we've been limited to in the past.
One thing I did notice, however, is that a small piece of software is actually also loaded onto the device when accessing for the first time. This is presumably to make things work properly and the required permissions are minimal and can be restricted anyway, so it doesn't seem too concerning. Still, it would be nice to see the developer mention this in the description.
