Target exe for Android ABI(ndk build)

I have an android system with two different CPU ABI - armeabi-v7a and x64 .For which one I have to build the application code to get it working.My application (in c language) anyway doesnt run for either of the platforms. OR is there any common tool chain with which I can build the same. arm-eabi-gcc?

The NDK contains all the toolchains you need to run your program on Android platforms.

To setup the architectures you need to compile to, you should set the APP_ABI variable inside Application.mk or pass it to the ndk-build command.

APP_ABI:=all will make your ndk project being built for all the supported architectures: armeabi, armeabi-v7a, arm64-v8a, x86, x86_64, mips, mips64.

You can also list which architectures you want to build for: APP_ABI:= x86_64 x86 armeabi-v7a arm64-v8a and also use all32 and all64 as shortcuts to all the 32-bit and all the 64-bit architectures.

To determine which platforms are supported by a target device, you can call adb shell getprop ro.product.cpu.abi (preferred arch) and adb shell getprop ro.product.cpu.abi2 (second arch).

Starting with Android 5.0, use adb shell getprop ro.product.cpu.abilist instead, that returns a list of all the supported ABIs, sorted in preference order.

I don't think you can target completely different architecture (arm and x86) with android provided ndk (cross-compilers). You can target multiple ABI supported by arm with following variable

TARGET_ARCH_ABI

possible values are:

armeabi For ARMv5TE 
armeabi-v7a

for more details you can check this link.

To run in x86 or amd64 system you can normally use a gcc to create the .so file and use JNI to test functionally (remember Android F/W will be unavailable there).

If you are looking for rapid building-testing cycle I think it's better for you to use an x86 based emulator like AndroVM (now Genymotion). In that way you can write code for android device and test it real quick.
