 You'll need to replace `<name of the godot-cpp>` with the file that was created in [**Compiling the cpp bindings library**](#compiling-the-cpp-bindings-library). The command above targets `arm64v8`. To target `armv7`, use `armv7a-linux-androideabi29-clang` instead of `aarch64-linux-android29-clang`.
