Previously only METADATA_KEY_ALBUM_ART_URI/ART_URI were set, leaving notification/lock-screen/Android Auto consumers to resolve the cover art themselves. Likely due to internal scaling, a lower quality bitmap was loaded.
This commit adds a shared resolveUriAsBitmap() helper (extracted from AbMediaDescriptionAdapter.kt) and uses it to:
- Resolve and cache a bitmap on PlaybackSession once per
session (synchronously for local covers, asynchronously for server covers), then set it on METADATA_KEY_ALBUM_ART/ART once available, falling back to the URI keys until it resolves.
- Reuse the same helper in AbMediaDescriptionAdapter so the notification icon is resolved consistently.
PlayerNotificationService tracks the resolution Job and cancels/replaces it on each new playback session, invalidating the media session metadata once the bitmap is ready.
When we are backgrounded, these queue events build up and can cause
performance issues as the queue is processed. We don't need to process
these when backgrounded, so skip them.
Also add small delay when resuming for webview to load before sending it
update events
- Route hardware volume keys to Cast via MediaSession VolumeProvider
- Use CastSession.volume (0–1) mapped to 0–100; clamp and step by 1
- Update provider with actual device volume after each change (prevents stalls)
- Drop stream-volume/polling attempts and other leftovers
- Expose get/set/adjust device volume commands to the player
Removed blocking `while (!browseTree.isInitialized){}` in
`onLoadChildren`. Added `waitForBrowseTree` and `onBrowseTreeInitialized`
helpers to queue pending results until browseTree is ready. All
browseTree assignments now call `onBrowseTreeInitialized()`. This avoids
ANRs and high CPU when Android Auto requests children before init.
Replaced the infinite `while(libraryPersonalizationsDone > 0){}` spin‑loop
with an async counter callback. This prevents pegging the CPU if one
personalization never completes, and allows completion to trigger via
AtomicInteger decrement. Now the final callback fires only when all
libraries have finished loading.
Adds meta-data to the widget, allowing it to be used on the cover screen
of Samsung devices such as the Flip.
The widget renders as a 4x4 grid (not an optimal layout) but functions
for launching the most recent audiobook or controlling playback.
