Trigger
Use for Android TV playback screens, remote/D-pad interaction, Compose for TV player UI, or maintenance of an existing Leanback app that uses media3-ui-leanback.
Rules
- Start with
streaming-media-architecturefor ownership and telemetry, then specialize for TV. - Pin Media3 to
1.10.1through the version catalog. androidx.leanbackis formally deprecated. Its release page states the artifact and its classes are deprecated and points to Compose for TV.media3-ui-leanbackwraps that deprecated stack.- New TV apps MUST use Compose for TV (
androidx.tv:tv-material) with the standard Media3 Compose surface (PlayerSurface/ContentFramefrommedia3-ui-compose). - Use Leanback plus
media3-ui-leanback(LeanbackPlayerAdapter) only when maintaining an existing Leanback app. DO NOT add it to new code. - When an existing Leanback app is being modernized, follow the official migration guide: https://developer.android.com/training/tv/playback/leanback/migrate-to-compose
- On both stacks, design for D-pad focus, visible selected state, back/menu behavior, and transport keys.
- Keep video controls readable at TV distance and safe from overscan/system UI.
- Use TV-friendly browse/playback flows; avoid phone gestures as required controls.
- Test focus order before claiming the TV UI is done.
Example
New TV app (Compose for TV):
tv-material = { module = "androidx.tv:tv-material", version.ref = "tvMaterial" }
media3-ui-compose = { module = "androidx.media3:media3-ui-compose", version.ref = "media3" }Existing Leanback app, maintenance only:
media3-ui-leanback = { module = "androidx.media3:media3-ui-leanback", version.ref = "media3" }Do Not
- DO NOT start a new TV app on Leanback or
media3-ui-leanback. - DO NOT ship a TV UI that requires touch.
- DO NOT hide focus state.
- DO NOT reuse cramped phone controls without TV spacing and focus checks.
