Step 1 of M8 (docs/android/PLAN.md item 9).
- compileSdk/targetSdk 36 (Play's floor since 2026-08-31). AGP 8.6.1
cannot build against 36, so AGP goes to 8.13.2 (the last 8.x) with the
Gradle 8.14.3 wrapper. Kotlin, KSP and Hilt are unchanged. All three
workflows install platforms;android-36; AGP 8.13 still defaults to
build-tools 35.0.0.
- release.yml also runs bundleRelease, signed with the same keystore,
and attaches the .aab to the Gitea release beside the APK (the first
bundle has to be uploaded by hand, and this is where it comes from).
- A last step uploads the bundle to Play's internal track through the
Play Developer API v3 edit flow. The OAuth token comes from a
service-account JWT signed with openssl; the key is the new
PLAY_SERVICE_ACCOUNT_JSON secret. While that secret is unset, the
step warns and skips. The step runs after the Gitea release, so a
Play failure never holds back the APK.
