punktfunk/.gitea/workflows/android.yml

# Android client CI (Gitea Actions). Builds the Rust JNI core (crates/punktfunk-android) via
# cargo-ndk for both shipping ABIs and assembles the debug APK (clients/android). Mirrors apple.yml
# but on a Linux runner — the NDK is cross-platform, so no self-hosted host is needed.
#
# Prereq: the runner needs ~6 GB free + internet (it pulls the Android SDK/NDK and the Gradle
# distribution in-job). If android-actions/setup-android is not mirrored on this Gitea instance,
# replace that step with a manual cmdline-tools download, or bake an `android-ci` image like
# ci/rust-ci.Dockerfile. Emulator instrumentation tests are deferred until a KVM-capable runner
# exists (they self-skip otherwise, like apple.yml's RemoteFirstLightTests).
