# HACK(eddyb) this is a minimal setup to allow testing the Android build on NixOS.
#
# Tested in `NIXPKGS_ACCEPT_ANDROID_SDK_LICENSE=1 nix-shell android.nix --pure`,
# by running the following commands (x64 target is for the Android Emulator):
# rustup target add aarch64-linux-android x86_64-linux-android
# cargo apk build -p example-runner-wgpu --target aarch64-linux-android
# cargo apk build -p example-runner-wgpu --target x86_64-linux-android
#
# (you can also replace `cargo apk build` with `cargo apk run` to launch it,
# via `adb`, into either the Android Emulator, or a physical Android device)
