I'm trying to learn MediaSession, so I made an audio player app, but I didn't use MediaSession becuase I don't know how to, therefore, I can't handle the playback with headset keys, for example, hook key.
I need a simple example on how to play dummy audio with MediaSession, which has play and pause features.
The Universal Android Music Player Sample shows how to implement an audio media app that works across multiple form factors.
In the full guide, there's a media session and controller section you'd probably like to read.
You can find MediaSession implemented in the UAMP sample inside MusicService.
