Summary:
1. scripts/build_android_libtorch_and_pytorch_android.sh
- Builds libtorch for android_abis (by default for all 4: x86, x86_64, armeabi-v7a, arm-v8a) but cab be specified only custom list as a first parameter e.g. "x86"
- Creates symbolic links inside android/pytorch_android to results of the previous builds:
`pytorch_android/src/main/jniLibs/${abi}` -> `build_android/install/lib`
`pytorch_android/src/main/cpp/libtorch_include/${abi}` -> `build_android/install/include`
- Runs gradle assembleRelease to build aar files
proxy can be specified inside (for devservers)
2. android/run_tests.sh
Running pytorch_android tests, contains instruction how to setup and run android emulator in headless and noaudio mode to run it on devserver
proxy can be specified inside (for devservers)
#Test plan
Scenario to build x86 libtorch and android aars with it and run tests:
```
cd pytorch
sh scripts/build_android_libtorch_and_pytorch_android.sh x86
sh android/run_tests.sh
```
Tested on my devserver - build works, tests passed

# Script's workflow:
|
|
# 1. Builds libtorch for android for specified android abisi (by default for all 4).
|
|
# Custom list of android abis can be specified as a bash argument as comma separated list.
|
|
# For example just for testing on android x86 emulator we need only x86 build.
|
|
# ./scipts/build_pytorch_androis.sh x86
|
|
# 2. Creates symbolic links to android/pytorch_android/src/main/jniLibs/${abi} for libtorch build output,
|
|
# android/pytorch_android/src/main/cpp/libtorch_include/${abi} for headers.
|
|
# 3. Runs pyotrch_android gradle build:
|
|
# gradle assembleRelease
