# Builds the Android app on our own runner (deploy/gitea-runner) and publishes it.
#
#   - Push a tag like v1.1.0: builds the normal and FOSS APKs, signed with the upload key,
#     and attaches them to a Gitea release for that tag.
#   - Actions > Android > Run workflow on a branch: a test build, uploaded to this repo's
#     Packages (generic package "musicshare-android", version = branch + short commit).
#
# Uses only `run` steps (no third-party actions), inside the image from deploy/android-builder.
# Secrets (repo Settings > Actions > Secrets):
#   UPLOAD_KEYSTORE_BASE64  the upload keystore, base64 -w0
#   MUSICSHARE_UPLOAD_STORE_PASSWORD, MUSICSHARE_UPLOAD_KEY_ALIAS, MUSICSHARE_UPLOAD_KEY_PASSWORD
#   RELEASE_TOKEN           an access token with write:repository and write:package
