Device logcat (Pixel 6 Pro / Android 16) showed audio_service throwing
on every state broadcast:
java.lang.IllegalArgumentException: You must specify an icon resource
id to build a CustomAction
at com.ryanheise.audioservice.AudioService...
The #57 MediaControl.custom favorite makes audio_service build a
PlaybackStateCompat.CustomAction whose icon id resolves to 0 on real
builds; the exception aborts the ENTIRE media notification, so nothing
posts to the tray or the watch (emulator tolerated it). Not a
permission / PathParser / FGS issue — POST_NOTIFICATIONS was verified
granted. Pre-#57 there was no CustomAction, matching the regression.
Remove the custom favorite control; the notification is rebuilt with
only the standard transport controls (audio_service ships their icons).
customAction handler / refreshFavoriteControl left as harmless no-ops
to minimise churn. Like/favorite remains in-app + lock screen.
