• Running Android application

Building C++ library

$ cd ./cpp
$ mkdir build && cd $_

$ export ANDROID_NDK_VERSION='25.1.8937393'
$ export ANDROID_NDK_HOME="$HOME/Library/Android/sdk/ndk/$ANDROID_NDK_VERSION"

$ echo $VCPKG_ROOT

$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="../install" \
    -DCMAKE_TOOLCHAIN_FILE="$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" \
    -DVCPKG_TARGET_TRIPLET="arm64-android-v8a-v30" \
    -DVCPKG_OVERLAY_TRIPLETS="/ABSOLUTE/PATH/TO/cpp/misc/vcpkg/triplets" \
    -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE="${ANDROID_NDK_HOME}/build/cmake/android.toolchain.cmake" \
    -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=30 \
    ..
$ cmake --build . --target install

$ cp -an ./vcpkg_installed/arm64-android-v8a-v30/* ../install/
$ ls -L1 ../install/

Running Android application

1. Open ./android folder in Android Studio;
2. Set CMAKE_PREFIX_PATH to /ABSOLUTE/PATH/TO/cpp/install in ./android/app/build.gradle.kts;
3. Make/build the project or just click Run 'app'.
