Use case description

I develop and maintain an audio app that stores the covers for its media as files locally (in external storage). I want to use those local files as the artwork in a MediaItem.

Proposed solution

setArtworkUri in MediaMetadata.Builder could accept Uris with the scheme file:// and content://

Alternatives considered

(1) I can convert the local cover file into a ByteArray and pass that to setArtworkData. But that solution uses more memory compared to just setting that artwork Uri.
(2) setArtworkUri somewhat works with file://-Uris ... in the sense that the correct cover is displayed in the app's Notification. But MediaDataManager throws a FileNotFoundException (Permission denied). So I guess other clients of my app will not be able to see the cover.
