Expected result
The System UI playback resumption notification is not shown.
Actual result
There is a System UI playback resumption notification after the demo app has been treminated.
It's currently not possible to do that with MediaLibraryService on API 30.
On API 30, allowing to connect a browser the MediaBrowserService seems sufficient for posting a playback resumption notification. onLoadChildre/onGetChildren is never called with package com.android.systemui:

On API 31, the browser with com.android.systemui insists in calling onLoadChildren/onGetChildren and checks whether there is a playable child.

For Media3 1.0.1 there is no fix besides not adding
to the intent filter of the
MediaLibraryService. Please note that whenandroid.media.browse.MediaBrowserServiceis not added clients likeAndroid Autocan not discover the service either.We are working on a fix for this.
Allow `MediaLibraryService` to reject the resumption notification
