Build Validation Layers with Android CMake

Gradle‘s CMake library project in this directory builds layers into AAR; the project could be directly added into application’s gradle projects

Pre-requirements

Build ShaderC binary

• Building from Github Repo source

1. cd android-build
2. ./update_external_sources_android.sh
3. ./android-generate.sh

Extra Steps if building from NDK's source tree

   cd ${your ANDROID_NDK_ROOT}/sources/third_party/shaderc
   ndk-build  APP_ABI=armeabi-v7a APP_STL=gnustl_static NDK_TOOLCHAIN_VERSION=clang NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk libshaderc_combined

Adding layer module into Android Studio application project

1. app's settings.gradle, add

    include ':layerLib'
    project(':layerLib').projectDir = new File('/path/to/cmake/layerlib')

2. app's build.gradle:

dependencies {
    // force debug layer lib for packing
    compile project(path: ':layerlib', configuration: 'debug')
}

BUILD_IN_NDK variable in layerlib/CMakeLists.txt could detect whether the source is from NDK or github repo clone, and would configure the file paths accordingly

Tested

Build on Mac OS, Nexus 5X test phone. Equvilaent build scripts for Windows OS are at the same directory.
