Building application from source code

./gradlew downloadDependencies
./gradlew assembleFreeDebug
./gradlew installFreeDebug

Alternatively, build in a Docker container to keep the host clean (Dockerfile, no host NDK/SDK needed):

./docker/build.sh

The first run builds the unipatcher-builder image automatically. The debug APK is placed at app/build/outputs/apk/free/debug/. For details run ./docker/build.sh --help.
