I am beginner android developer. I am trying to create a simple game using android-ndk and OpenGL-ES, but the emulator unfortunatelly doesn't support OpenGL. What is more it is a bit slow. So, I am planing buying a tablet with android. Maybe Asus Transformer or Acer Iconia. But I am afraid, will I be able to test my applications on these devices? Aren't there any limitations about that? I read some information on the topic and I suppose that I can install apps signed with the debug key...
Yes, you will be able to test the applications on any android tablet that has an equal to or higher version of android to your app. For how to do so look here: http://developer.android.com/guide/developing/device.html.

In continuation with this question. I am asking this question.
I installed Android Studio. I installed Unity 3D. I followed tutorials of Java-Android Studio and Unity. Nothing worked well because of the reason that they need the latest version of ARCore and neither my mobile nor emulator is compatible with it. I am exhausted searching for alternatives.
I didn't find any tutorial or guidance related to developing Augmented Reality Android apps. Please suggest me a reference that works on Ubuntu system without the need of the physical mobile, but with an emulator, if possible.
Note: Please provide a reference that is relatively easy to test small app initially so that I can proceed forward. I am saying this because of the reason that I am working from almost 3 months but didn't run a small AR app either in the emulator or in my mobile (Redmi Note - 4).
You should check 8thWall. It runs on almost all phones and it has SLAM as well. You can not use it with emulator but it has an application called XR Remote in which you can test your code without building for Android or iOS. Minimum requirement for Android is Android Kitkat (4.4) or higher and for iOS Minimum iOS 7.0 or later is required.
As the owner of the question stated 8thWall can not be used with Linux. As an alternative [ARToolKit] can be used. It is an open source AR framework. For more details you can refer here and here
I'm converting my Android app (apk) to Blackberry OS 10 (bar).
Everything is ok if i install the bar file to my BB.
But when I try to upload to our BB server to deploy to software to the Z10, i have the problem:
"Qnx/Android" is not supported
I found the root cause here:
It is currently not possible to add Android applications to the work
perimeter on the BlackBerry Playbook tablet or BlackBerry 10
smartphone; this is by design.
Since all applications added to the BlackBerry PlayBook tablet or
BlackBerry 10 smartphone via BlackBerry Device Service are installed
in the work perimeter, Android applications cannot be installed.
Alternatively, Android applications can be successfully downloaded
directly into the personal perimeter on the BlackBerry PlayBook tablet
or BlackBerry 10 smartphone.
What's should i do now?
I need to install my app to more hundred of BB10.
Can i reuse my Android code?
If can't, what's the best solution, best language if i must you write all the code from scratch.
Thanks you

You can't reuse any of your code.
The best option depends on the type of application. If it is reasonably complex, with interaction with on device stuff like location, then Cascades/C++. Alternatively, you might consider html5. Have a look round here for more:
https://developer.blackberry.com/
Playbook is another curve ball. If you have to support that then you can't use Cascades.
And to be honest, there is a certain amount of personal preference involved here too - what do you like writing in?
Just a FYI, it took me about 6 months, part time, to feel fully comfortable with C++/Cascades. This was from nothing, no C, no C++, no experiences of GUI design tools and a different IDE. But I created my first app, a really simple one, in two weeks.
i am developing andriod app. On GUI development, I have issue how to test if GUI works on different Android phones (i mean with different screen size, density and etc). How i can check if everything is correct?
You are asking for the hardest thing to do in Android development :)
Read Supporting Multiple Screens.
If you are targeting motorola devices, here are a bunch of SDK addons for the emulator.
If you need to test a specific device, you can try using perfectomobile.
Can't you test that with the emulator?
You'll have to create multiple AVDs ("Android Virtual Devices") with the settings you want for Resolution, Density and so on.
I usually use two steps:
Create a few emulators with different screen-sizes and versions of Android.
After succesfully testing step 1 I hand out my app to some friends with different Android phones and let them test my app.
You can test your android app. without using any mobile phone..
Just go through the link(if your app is using flash) here..

I want to start Mobile Phone development, but I am very very new to this area, I have 3 choices: iPhone, Nexus One and Windows Phone. I believe Nexus one atracts me more. But I have never bought a smart phone. My questions is: If a buy one Nexus One from Best Buy store, can I use it for developing Android applications?
I appreciate your help, nobody helps me with this question and I am a novice in smart phones.
Thnak you

For the most part you do not need a device to start doing mobile development. You can download the Android SDK complete with an emulator here: http://developer.android.com/sdk/index.html
If you're not sure which kind of development you'd like I'd recommend downloading the toolkits for all the major ones, trying them out, and then decide.
Android
Windows Phone
iPhone
Blackberry
You don't develop mobile software ON a mobile device. You use them to test.
If your choice is Android vs. Windows vs. iOS, then you need to decide what kind of software you will be writing.
For native apps, all 3 use very different development platforms (java vs. .net vs. objective-c).
If you're going to go the HTML5 + Phonegap route, then it really doesn't matter. And you really don't need a physical device anyways...you can always test on simulators.
If you want to do ANY app dev for iOS, though (be it native or phonegap) you WILL need OSX on a desktop/laptop computer.
First decide what operating system you want to work on as DA suggested. If you have decided to develop applications for Android then iPhone and Windows phone is of no use to you.
Only those devices having Android Operating System you can use, Nexus One or Samsung GalaxyS are good options.
But before buying anything you can start developing applications as there is emulator provided which does most of the work that a device does.
I really want to get into Android programming but I only have access to company resources right now. I have the money right now to purchase a XOOM or a development laptop. Is it possible to compile Android apps using the command line on the Xoom while using other apps to write the program files.
What would seem like a dream environment would be if I purchased a XOOM and a BlueTooth Keyboard. Am I dreaming? Developing using older Android devices was naturally limited by the screen space of the device and the underlying hardware also.
No, as far as I know, you cannot develop Android applications from within Android. You will need a Windows, Mac, or Linux desktop environment to develop Android applications. Visit the Android Developer site for additional info on the SDK.
Go for the development laptop, and test your applications on the emulator. Initially you can get friends to test them out on their android for you, and hopefully by the time you make something important enough you will be able to afford your own android.
Check out AIDE. It can build and deploy apps natively on Android.
Google doesn't have a version of the SDK that runs on an android device, although as devices become more powerful this would be a pretty awesome thing to have.
You'll want the laptop, since it can emulate different android devices.
Buy the laptop and get a cheap phone on craigslists.
Although, the XOOM emulator doesn't work at all, so if you want to develop specifically for that tablet it's a good idea to buy it. It's impossible to emulate android 3.0 on any computer on earth :)
