First Media3 wiring. PlayerFactory builds the process-singleton
ExoPlayer with our shared OkHttp + SimpleCache chain; the
MinstrelPlayerService (Phase 6.2) calls build() in onCreate.
Chain shape:
ExoPlayer
.setMediaSourceFactory(DefaultMediaSourceFactory + CacheDataSource)
.setAudioAttributes(USAGE_MEDIA + CONTENT_TYPE_MUSIC, focus=true)
.setHandleAudioBecomingNoisy(true)
CacheDataSource
.setCache(SimpleCache(audio_cache dir, LRU evictor, Room standalone DB))
.setUpstreamDataSourceFactory(OkHttpDataSource over shared OkHttp)
.setCacheWriteDataSinkFactory(CacheDataSink full-fragment)
Built-in audio focus + becoming-noisy handling — Media3 owns these so
no audio_session-equivalent code path is needed (the Flutter app had
~40 LOC for the same; here it's three lines of config).
simpleCache exposed as a PlayerFactory val so the AudioCacheEviction
Worker (Phase 12.3) can call removeSpan() during 2-bucket eviction.
CacheConfig (defaults 200MiB liked + 150MiB rolling) — Phase 11
Settings will let users override.
Bumped Media3 1.4.1 -> 1.10.1 (current stable, AGP 9 + Kotlin 2.3
friendly, MediaSessionService now extends LifecycleService which
makes 6.2's lifecycle-aware patterns cleaner). Breaking changes
between 1.4 and 1.10 don't affect our usage (DRM, FrameExtractor,
ChannelMixingMatrix — we use none).
