Reproducible in the demo app?

Yes

Reproduction steps

MediaSession.setSessionActivity(PendingIntent) does not accept null. This prevents unsetting the session Activity when it is no longer valid. The best I can do is cancel the PendingIntent.

MediaSession.Builder does not require setting a session Activity. Why does setSessionActivity attempt to prevent this?

In my use case I have a long-lived media session transcending major changes in app state.
