Building media apps on Wear OS
summary
Shows a production-ready Wear media stack: Wear Media Toolkit (Horologist libraries), Media3 ExoPlayer integration, a sample app that syncs playlists, downloads tracks, shows artwork, uses audio offload and ongoing activity, and blocks accidental wrist speaker playback until a Bluetooth device connects. Demonstrates wearable UX like a crown-aware volume screen and download cancelation. Macrobenchmark results cut cold start from ~900 ms to ~700 ms and player readiness from ~4 s to ~1.5 s; a 50 s buffer takes ~12 s to fill over Wi‑Fi.
