I want to record calls with android NDK. Previously i was using sdk and recording calls but in few specific phones and new released phones at (API Level 24/Nougat) or higher call isn't recording.

I found an old phone and tablet that i was using to develop Android apps on. The computer that had the codes for those apps was fried by lightening. It's there a way to pull the published apps of those devices to the new computer and continue to develop them in Android studio?
You can use any of the Android Decompiler to get the source code from a compiled APK. If you were using Proguard you will still have some challenges in the names but as you have written the code you can simply replace the mangled names with correct one.
What's the function Android TV and Android Wear in Android SDK manager in Android studio. Do I need to install these for all Api
Those two components provide you a way to develop for Wear and TV apps, respectively. If you only want to develop a phone app, you are not needed to install those.
You can see more about the Android Wear SDK here and Android TV SDK here.
Android TV is for Android TV. If you don't need your app to run on an Android TV (which has a tiny marketshare anyway), then don't worry about it.
The same goes for Android Wear. If you don't need your app to run on an Android watch (which has a tiny marketshare anyway), then don't worry about it.
Also, you seem to misunderstand how Android versioning works. If you want to develop on a phone or a tablet, just download the latest version, you do not need to download the previous versions (except may be for one compatibility library that you might need).
In other words, if you're just a beginner, download as little as you can. Most beginners download almost everything and that's just a waste of space.
I 'm just getting started with Unity 3D and I 'm going through android games development learning and I wonder how to setup Unity to work with android studio ?
For the majority of your tasks, you will not be working in Android Studio. You will be working directly in Unity. The only reason you would need to work in Android Studio would be to create native plug-ins for additional functionality that is not provided in the Unity Engine.
A detailed description of the requirements to build for Android are available in the Unity3D documentation. An abbreviated description:
When you are ready to test on your device, you will build for Android: File>Build Settings, and select Android from the list
You will need to have the Android SDK installed, and have at least one API Level installed using the Android SDK Manager (minimum).
In Edit>Project Settings>Player Settings, open Other Settings. Choose the Minimum API Level for your game. This API level must be installed using the Android SDK Manager
Finally, When you've finished building, you will have a .APK file.
You can copy to your Android device, and install with a file manager. -OR-
You can install it on an Android Emulator.
I hope this helps in some way!
Running Android Studio 1.0.2 for Windows
Using a new Blank Activity or Blank Activity with Fragment project (bug happens with both). Haven't modified anything in the code yet. Using API 10: Android 2.3.3
Often immediately, sometimes shortly after I drag or edit my first/any UI element into activity_main.xml, Android Studio freezes and I have to close the process in task manager to get it to close.
I notice that in Task Manager the Android Studio Windows Launcher is taking about 25-30% of my CPU while its frozen.
What's going on here? Any ideas?
....
I may have found a solution for this.
I theorized that perhaps it was just the windows display that was frozen (the visual rendering of the Android Studio program itself) and guessed that perhaps this was using a DirectX device to do the rendering of the Android UI.
I happen to have another app running on my computer that uses a DirectX device for rendering (SimpleJungleTimer, an app I programmed with a DirectX overlay for League of Legends jungle timers). After I shut down this app Android Studio appears to be working properly (not freezing when working with the UI anymore)
Ultimately it sounds like this is a bug with Android Studio itself where they don't properly kill / reload the DirectX rendering device when it is in conflict with another app's active DirectX device (something that the android studio developers should probably fix), however until the android studio developers fix this you should be able to get around this bug by making sure any other applications that might use DirectX for rendering are shut down while coding in Android Studio so that their DirectX rendering devices don't conflict with Android Studio's DirectX device.
I done mobile application in j2me platform. Tested successfully in Symbian os mobiles ..like nokia,samsung..sony ericsson. I have doubt in j2me supports android and blackberry mobiles.
You can run j2me application on Android with little effort, but user experience is not that of "native" android applications. So if possible, rewrite the application for Android SDK. This is not that hard, though many parts of code will need to be rewritten or rearranged.
