[APP REQUEST] Virtual Machine for Android, deatils inside. - Galaxy Tab 2 Q&A, Help & Troubleshooting

I have a Galaxy Tab 2, 10.1 SGH-i497, rooted, stock, its the AT&T 4G LTE version. I want to request that someone with more knowledge than me in development to develop an app for root users to allow the home screen to be separated, and run two simultaneous instances of the home screen, in portrait mode. NOT the false "split screen" floating apps Samsung is so proud of, and everyone is talking about, but actual separate home screens each running in a virtual environment. That can run ANY app on the device and function just like your normal home screen. I think by extension these separate virtual home screens would be needing separate databases and configurations files and whatnot. Think virtual machine for android.
Is this even possible? Or would I need to install a baked or 3rd party ROM to get such functionality? Seems like this sort of addition would need it's own firmware, but I could be wrong. The XDA crowd has amazed me in the past with works of brilliance. This is not just a lone request, the entire market for galaxy tablets, note tab and all variants, as well as other android tablets, are clamoring for this. I will gladly test, i have fully functional test environment including real time logcat.
Happy coding, thanks in advance for all responses.

Android as a viable desktop - Discuss

Hi Folks
Just wondering if anyone has seriously considered or is using android on the desktop?
Hear me out here!
Since stopping using windows as my main desktop OS about 18 months ago, I've been enjoying all the fruits that open source has to offer. I think I must have trying nearly every flavour of Debian/Ubuntu distro's and currently using some Mint/Gnome 2 setup. partly due to Unity's immaturity as Multihead desktop and probably part of me can't let go of that "Start" menu analog.
Through all my "testing" however I've still not settled on the right desktop/development environment, I've tried them all, really, I feel like I given pretty much every Window Manager out there a go, I especially like the blank canvas of openbox although I've got real work to do as well, so configuration wise It's not something I want to know right now
Part of my issue is I've got a what I would consider a bit of an edge case when I comes to setup. My current setup is over 3 Monitors ( I was considering 6 but thought I might get whiplash from moving my head too much :laugh: )
Right now I live my live mostly in Terminal Windows and Bash Prompts and do most of my hacking In gedit with some plugins ( maybe not the most productive but it's kinda of working for me at the minute )
After giving the Android x86 project, It got me thinking whether It would be a viable option. I know android certainly has the capability to run over multiple monitors although whether I would have to do a bit of hacking on the Framebuffer internals ( add extra ones etc ) has yet to be investigated.
With regards Android Development it kinda of makes sense to Develop right there in it's native environment ( I'm talking Kernel/System Level here not apps) . Compiling the AOSP etc should still be the same process.
So Yeah, Android on the Desktop - Discuss
I'd be interested if anyone has been crazy/foolhardy/patient enough to go down this road and are just keeping quiet about it and If there's any gotcha's etc to think about before embarking on such a mission.
Android is better off on smartphones and Tablets and Windows in better off on Desktops and Laptops.
As Im an avid gamer, I wouldnot mind having Android on my Desktop. Android has limited no. of good games but Windows dont.

Thanks, That's the kinda of thing, I was not aware of this project/product ( although still vapourware til next month ) At least I'm not crazy for thinking it
I spent a week or 2 only using an hp touchpad, to see if I could get away using it as a desktop replacement.
The biggest problem I found is that the apps aren't really designed for serious productivity. Google docs is great for viewing things, but is very irresponsive on large documents, and doesn't like fancy formatting. Browsing was a nightmare. I had 3 or 4 different browsers, because each had different plugins, flash support, user agents, etc. Many browsers were unstable, and flash always caused random crashes and other weird problems. Gmail is useless for attachements, and there is no reasonable text editor.
It's doable, but you may have to spend a while finding apps to replicate all the functionality you expect from your PC.

As a desktop replacement I'm not so sure but Android can definitely work as a netbook replacements.
It also depends what you use ur desktop for. Anything more that web browsing and email, I'll still prefer having a full fledged OS on it.

An android desktop could do mail, web browsing, multimedia, usenet or torrent downloads, games, dlna streaming, ebook reading and text editing (writing, creating pdf, etcetera) well.
It would not be able to do some of the things a desktop can do such as transcode video, run open office, use pc accessories, etcetera.
This is primarily because android is a mobile oriented os though it's likely that other than the use of pc accessories developers will write apps to get android doing even more as it is now a very popular tablet os and tablets often get used as a pc does.
Android could be a desktop for general everyday use right now but not for everyone.
For now windows and linux still beat android for both software, peripheral support and overall os speed making those better options however its also easier to have a new user mess those up than it is to mess up android so for general use it could be a good option.

Short version: Currently, I would say no. In the future (2+ years minimum), I highly expect Android to compete for the desktop. It comes down to software moreso than hardware.
TL;DR version: Let me start by saying I've owned quite a few Android smartphones, and I've worked on twice as many for friends, family, etc. I've also owned a couple of Android tablets. Without trying to sound too cynical, let's just say I've been around the block when it comes to Android devices When it comes to phones, Android is as perfect as any OS could be. With it always improving, there's always more to love. For tablets, the experience didn't come off to a great start, but there have surely been improvements since. The first high-end tablets, as well as cheap alternatives, ran on Gingerbread or older. My first cheapo tablet ran on a rare version of Android 2.0 Eclair. Let me tell you, it wasn't pleasant at all! I decided to wait for Honeycomb to come out before trying another tablet, and that's when I picked up an Acer Iconia A500 with the sole intention being to use it like I'd use a computer. The only computer I had at the time was a 10" Acer netbook, so once I bought the tablet, I sold the netbook right away. Now, I will admit that I waited a little bit to see how Honeycomb took off. By the time I got my Iconia, 3.2 was just coming out. In order to completely replace any kind of computer, I knew I would need at least 3 accessories: a stand, keyboard, and mouse. In my initial research, I learned that Android 3.0 didn't have mouse support by default. This was fixed by the dev community here, and Google was prompt to add mouse support in the 3.1 update. So by the time I had my Iconia running 3.2, everything appeared to be ready as far as being a PC replacement. Or so I thought. One major reason I picked the A500 over other tablets was the fact that it had a full-size USB port right on the tablet itself, whereas others either didn't have one at all (Xoom, Galaxy Tab), or it was only available on the keyboard dock (Transformer). As a computer replacement, USB was important to me. It didn't take long for me to realize that a tablet as a PC replacement wasn't the most ideal choice at the time. While there are plenty of apps available to perform many different tasks, the real problem I had was with the way Android itself handled. The apps were more than good enough. There's email, web browsing, multimedia, word processing, etc. The problem is the way Android feels with a keyboard and mouse. One major problem for me was that Android has no proper right-click support with mice. It simply works like a back button. I feel that right-click would be more natural as the functionality of a long press. Another issue I was constantly trying to deal with was the amount of clicks required to complete simple tasks. I could do the same tasks twice as fast on any computer running Windows or Linux. This caused more frustration than anything else. File managers were generally really good - there's actually a couple that I really like a lot, but navigation was always an issue. It wasn't only file managers, but within several areas. Once again, this goes back to needing more clicks for the same tasks, and long pressing where a simple right-click would feel better. While the move to ICS was a huge improvement in performance, it didn't really solve anything with productivity and ease of use. USB support was also hit or miss, and a lot of it has to do with drivers. Now that's understandable, as most hardware venders don't expect Android to be the host OS. Hopefully this changes some day. Eventually I ended up trading the tablet and all the accessories for a mid-range laptop which I use now. I have this system triple-booting between Windows, Linux, and Android (android-x86.org). The same problems I faced with the tablet, I also face with ICS on my laptop. I find myself only booting to Android once in a blue moon, and it's always just to show off to my friends. Any real work is done with one of my other OS's. There's definitely a lot of potential with the Android platform as a desktop OS, but I feel like it's still a couple years away at least. There are still a few minor annoyances trying to use Android as a computer that need to be addressed. Maybe by the time Android 6.0 or 7.0 is released, it will put up a good fight for the desktop. Only time will tell. Another viable option is phones that dock to a computer with a desktop interface. Anyone remember Canonical's plans? Also keep in mind Linux kernel 3.3 which adopted Android natively, which is a huge step for Canonical and their Ubuntu-Android dreams.
i have been using android since 2008. The only thing i can tell you is Android can replace netbooks but not laptops and desktop. I used macbook for a year or so but I went back to windows.
HP Touchpad replaced my netbook.70% of the time i use my hp touchpad to chat, browse and play videos.
But when it comes to work or college work I go back to my good ol' desktop or laptop because
google spreadsheet is nowhere near MS Excel
google docs is nowhere near MS Word

I coming to that conclusion...... More for on the move devices, Although there some good stuff going on with the 10ft Experience (Android on TV's) at the moment.
It is also interesting to hear how people interact with their devices,
I'm far from an average user..... If i'm not developing with/on android I don't what to do with it :laugh: I think that's why my tablet has a keyboard and mouse plugged into most of the time
Thanks for the Input.

Brilliant That's exactly the type of responses I hoped for, a man whose got he's knees dirty in these dam robots on the desktop ... little long but I did read it.
[Short Version] In Summary I'm inclined to agree with you give it a couple of years, As a developer I could probably fix it up but I probably wouldn't be finished before google etc sorted it themselves[Short Version]
Here's a more verbose reply :laugh:
I have seen some 2.x tabs in my time, trailblazers but not nice.... I presume you gave the 1.6 x86 one a go as well then? Just for kicks.
I've been using a mouse and keyboard on my tablet, an Archos G9 through a usb hub which also has full size usb slot..... I've never really twicked onto the mouse lack of context menu/right click being an issue until you pointed it out, I can see how it would become an irritant after a while unless you're a MacUser than one button should be fine
The right mouse button acting the same as long press would be a vast improvement, I'll probably have a look at what development effort is involved in that ( or at least add it to the pile of interesting stuff I want to do with my time )
I've found the keyboard to be useful, Shortcut Keys are generally the same as there desktop counterparts. Take Ctrl+L to type a web address in your browser for example and If I dig around the android source code for a while I'm sure I could find some more unpublished ones or add my own and help on the number of click navigation issues etc .
USB Support is not a problem with each iteration of Android it gets better internally and I'm currently working with the opinion that if a linux driver exists I can compile it and at least get android the recognize the device... I've been deep in the USB Internals with android for the last few months.
On the Androidx86.... I've not checked the project in a while, there maybe have greater focus on solving some on these usability issues.
With regard to phones and docking I do remember canonicals plans ( wasn't that earlier this year) or are you talking about the circa 2009/10?!? ubuntu proposed project to run apks directly on your pc? essentially running the dalvikvm/surfaceflinger framebuffer management, support services on ubuntu with an X Window for the app.
The latter I feel is highly possible especially with android fully "unforked" in the kernel - not looked at the full details but I presume that includes all androids system level binder stuff and their shared memory modules and the former, I think a manufacturer release something called "Android in a Window" (Motorola or LG, maybe) An interactive android window on the desktop... also motorola's Webtop looks interesting.
I've written enough, Thanks for the Input

It runs in virtualisation fine and there are a few PC's that can run it natively, I would bet Jelly bean will run on x86 without fuss.

I've had android ICS x86 on my Acer W500 (a windows tablet) for a little while now. It was installed along side the Windows 8 Developer Preview which expired and shuts down after a few minutes of use now. Instead of updating it to the W8 Consumer Preview for more time I just started using ICS full time. With my tablet in the "dock" (which is just a keyboard really) and a mouse hooked up I used it for days as a PC replacement (the power supply in my normal desktop died).
Android would be totally fine as a desktop OS, but apps would have to start being designed with that in mind.
Think about it:
You can't have multiple windows open at once on the screen for serious multitasking. What if I want to have a terminal/command prompt open while I reference a document in the web browser? With android I'm going to be switching between fullscreen apps.
The OS will have to be redesigned to allow for that capability and then new apps will have to be written to able to take advantage of it. Is it possible? Absolutely! Is it ready to be your desktop replacement? Not yet!

I would say there is arguments for and against sizeable apps (I suppose that describes it), Personally I run multiple monitors and generally have Maximised Windows all the way, obviously every use case is different but I think android would become "just another window manager" and lose some of what android is If it had totally free window placement.
It is also assuming the current desktop metaphor which is in use today is the best/most productive way of interacting with the machine.... Maybe we're just blindly doing it because we've all be trained to think like that, and it's always been that way.
I don't claim to have the answers on any of these points though
I suppose the only thing I can do is stop talking and start doing, "try it yourself" as we say in the "trade" .....I've got a laptop I could give it a blast on, I can at least try a multiple monitor test with that with out too much disruption.

You might want to read the full thread guys It's kinda what we're talking about, check the Androidx86 project out if you've never seen it before
Actually with apps like overskreen and the open source standout library which lets apps float, so you can have several open at once on screen together and swap between them, you could multitask with multiple open windows.
It's a new approach but already finding favour on tablets.

If I am doing some coding on my PC (running Ubuntu) I use i3-wm which is a tiling window manager. I find the best option is to have all applications full screen and switch between them quickly using keystrokes. The same thing can be done with a theoretical Android Desktop.
I think the case for an Android Desktop is a strong one. Just looking at mobile phone shops and sites, Android is the most popular firmware for smartphones on the market so the amount of people owning one is only going to increase. With that it means that online communities like this site will get bigger with more people offering support and development. An Android desktop might not have the same look and feel as the smartphone version but if it can emulate the same functionality i.e. the way to do something on a smartphone is the same as on the desktop then the leap from smartphone to desktop won't be so hard for people. As you will have the same underlying platform, the same will apply for developers so it means application development on the Desktop version should in theory be faster.
That's a way of doing it but my preference would be a convergence of devices where say I can plug my smartphone into a docking station which hooks it up with a monitor, keyboard and mouse or like the Assus Padfone where a smartphone can be pluged into a tablet dock which turns it into a tablet.

Android phone powered Desktop

Android devices are so powerful today, and the hardware is becoming so powerful that I don't think that the software is utilising that.
We already have much of the technology in devices of today to enable a desktop environment to be streamed from our phones.
Display output: Chromecast (wireless display), MHL (Wired display & charger), etc.
Input methods: Bluetooth Keyboard & mouse, Accelerometer (to emulate mouse input), etc.
UI: Separate Launcher for the desktop UI.
With Microsoft bringing Windows 10 later this year as one OS for both the Phone & Desktop, surely that will allow them to work better in sync with one another, but that will still require a separate desktop computer and phone to create this kind of experience.
But Google now has the chance to simply output a separate UI from the same device that can display a phone UI all at the same time.
If we look at past launches of major Android builds then this coming Google I/O would be the perfect time to announce something like this, since they say that they usually deliver one major build that focuses on UI, and then one that focuses on major feature integration.
And not only would this allow for us to take our desktop with us everywhere in our pocket and connect wirelessly to any compatible display but also it could enable people in poorer economies to buy one device which could give them better access to the internet with a portable display integrated into the device, and also they could connect to the larger displays to browse the web or work on office documents with apps such as 'Google Docs'.
This could really be useful for people who wish to use their device in the work place too.
With Android mobile now offering multiple user profiles on their phones, surely they could create one profile for work, with all of their work apps available in both their phone and desktop UI's, but also a personal profile with all of their media applications & games available when out of work.
The desktop tower may still be useful for a few years to enable support for legacy applications whilst we are waiting for those applications to be ported over to Android/Android Desktop, but that shouldn't take too long considering how quickly we are see'ing apps becoming available to Android offering the kind of services that many of us desire, and if the developers only need to create one application back end for both the Desktop mode & phone mode, then it will be much quicker to bring apps to market with a small bit of time required to make a UI which can be scaled between the phone & desktop mode well.
There are multiple projects trying to create this very experience, but if it was a major part of the Android OS then finally people will get the experience that many people are waiting for, you only have to look at the comments on the developer pages of these projects to see that many people want this kind of experience.
With 64-bit now supported in Android too there is less of a reason to hold back this kind of experience.
I agree totally. Is this the only thread on this subject? Was going to setup Chromecast for video and Bluetooth for keyboard, mouse and audio. Doing this on a Jiayu S3A which is very powerful. Would like one place to discuss what works and what doesn't. Launcher options also need to be discussed.

[Completed] integrating android into factory touch screen?

Hi Guys,
This is my first post but I've used lots of the information on this website over the years. I build custom automotive interiors and have in the past 5 years integrated dozens of android and ios systems into cars. I'm trying to figure out a way to skip all the fabrication of dash bezels by directly integrating into the existing factory lcd touch screens.
I would like to use the existing touch screen in my Ford Edge to interface with an android tablet.
Ideally I'd like to take an existing tablet or phone that I own (Galaxy tab 2 10.1 or Galaxy s4 phone) and send the touch and video information to my stock Ford Screen
CarPerformance .se has a kit that includes an android system with a board that switches the source being sent to the screen with the push of a button allowing you to switch between the Ford information screen, android computer with touchsceen interfacing and video inputs
below is a link to the install instructions and a video of its operation
carperformance.se/wp-content/uploads/2016/05/My-ford-touch-Android-install-manual.pdf
carperformance.se/?product=2001-2014-ford-edge-android-system
(links are broken because I'm too new to post links)
I would like to know if there is a prebuilt video switcher similar to the one above that would allow me to switch between sources and woulld allow me to connect one of my android devices
The reason I want to do this on my own instead of ordering the above product is that it runs older android software and does not have cellular capability.
if someone could point me to the right information I would greatly appreciate it as I'm sure these screens are fairly universal however I don't know what exactly to search.

Calling All Developers - An Idea

I've been using 'SideSync' for a bit now, allowing me to mirror and use my S8+ on my laptop (see attached pic). Using multi windows I can even carry out rudimentary multi tasking.
It struck me that on a basic level, this is not too dissimilar to 'Dex'.
I'm not a developer, so I may be talking pure rubbish, but would it be possible to 'Frankenstein' the two programs?
Quite clearly, the 'Dex' dock isn't needed to connect to the laptop and within 'SideSync' the functionality to use mouse and keyboard already exists, the missing element here is the 'Dex' desktop.
My hope is that the desktop functionality can be integrated to the 'SideSync' app. Doubtful that it's as simple as I've laid out, but I have great faith in the talented boys and girls here.
Anyone?

Greetings, Somewhat tech Savvy retiree with a new device and needing a little help/info

I have a Tab S8 Ultra. I really like using DEX to emulate a computing environment. I have a small business and able to do just about everyting in need with it. However, it's not a 'true' laptop. Nevertheless, I want to cut ties with the laptop. There's one program I really need to do so. I have HGTV Home & Landscape Platimum Suite ver 3. It is, of course, windows based and my tablet is Android. Does anyone know of any available Drivers that will allow me to run it or is it even possible?
I just read an XDA contribution piece by Kyle Wiggers in January 2018 about "WINE - Compatability Layer for Windows. I'm really not sure if im on the right track here. However, this is the closest info I've found concering what I'd like to do. I'm wondering if there is any more development on this.
