Android

1. Build the armv7 plugin.

# NOTE: YOU MUST UPDATE DRACO_ANDROID_NDK_PATH FOR YOUR ENVIRONMENT.
export DRACO_ANDROID_NDK_PATH=$HOME/ndks/android-ndk-r20
mkdir armeabi-v7a && cd armeabi-v7a
cmake ../ \
  -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/armv7-android-ndk-libcpp.cmake \
  -DCMAKE_BUILD_TYPE=Release \
  -DDRACO_UNITY_PLUGIN=ON -DCMAKE_INSTALL_PREFIX=. \
  -DDRACO_ANDROID_NDK_PATH=${DRACO_ANDROID_NDK_PATH}

make -j install

2. Build the arm64 plugin.

# NOTE: YOU MUST UPDATE DRACO_ANDROID_NDK_PATH FOR YOUR ENVIRONMENT.
export DRACO_ANDROID_NDK_PATH=$HOME/ndks/android-ndk-r20
mkdir arm64-v8a && cd arm64-v8a
cmake ../ \
  -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchains/arm64-android-ndk-libcpp.cmake \
  -DDRACO_UNITY_PLUGIN=ON -DCMAKE_INSTALL_PREFIX=. \
  -DCMAKE_BUILD_TYPE=Release \
  -DDRACO_ANDROID_NDK_PATH=${DRACO_ANDROID_NDK_PATH}
make -j install

3. Archive the plugins.

tar cjvf libdracodec_unity_android.tar.bz \
  armeabi-v7a/libdracodec_unity.so \
  arm64-v8a/libdracodec_unity.so
