Android 13 Beta 1: granular media permissions

Beta 1 came out on 26 April 2022, two weeks before Google I/O, where betas had usually started. It opened Android Beta, so early adopters could enrol a Pixel and get the build over the air.

Granular media permissions. READ_MEDIA_IMAGES, READ_MEDIA_VIDEO and READ_MEDIA_AUDIO replaced READ_EXTERNAL_STORAGE for shared media in apps targeting 13. Images and video requested together share one dialog.
Keystore and KeyMint errors. New exceptions under java.security.ProviderException carry the KeyMint error code and say whether a retry can help.
Audio routing. AudioManager.getAudioDevicesForAttributes() and getDirectProfilesForAttributes() tell a media app where its audio will go and whether it can play directly.
Media controls started to come from PlaybackState actions, and the legacy copy of the Google app’s speech service was removed.
