v1074: Media player notification disappears, doesn't work

[hackbod]

In the last month or so, still in v1074, I've been seeing a problem where the playback information isn't being handled correctly by the system: it stops showing up in the media player in the notification shade, stops showing in always-on-display, media playback buttons won't work. Force stopping the app and then resuming playback will get it to work correctly for a bit, and then it stops working at some point.

Some analysis shows that the problem is that the app starts setting PlaybackState for the MediaSession to null, so it isn't being handled correctly by the system.

Here is a log when this happens:

Hi,
you were looking at COMMON_CHANNEL_ID, but PlaybackNotification is using its own channel for notifications.

There are many improvements in the latest build 2.0.0.1079 regarding this. Anyway, if you want the playback notification to persist, go to Options/UI/Notifications/Show in the notification bar and set the value to "Always".
