Usage:
  build_android [options]

Build AmneziaVPN android client. By default, a signed Android App Bundle (AAB) is built.

Options:
 -d, --debug                      Build debug version
 -a, --apk (<abi_list> | all)     Build APKs for the specified ABIs or for all available ABIs
                                  Available ABIs: 'x86', 'x86_64', 'armeabi-v7a', 'arm64-v8a'
                                  <abi_list> - list of ABIs delimited by ';'
 -b, --build-platform <platform>  The SDK platform used for building the Java code of the application
                                  By default, the latest available platform is used
 -m, --move                       Move the build result to the root of the build directory
 -h, --help                       Display this help
