MediaButtonReceiver component may not be null.

[emmjk]

I have a problem when i try to run QuizActivity , where an error is raised and theb app crashes . The android monitor points to MediaSessionCompat object creation statement and among the error lines logged is written MediaButtonReceiver component may not be null . This made me to think about the setMediaButtonReceiver method that we passed null as the value of media button receiver . Is anyone having the same issue??
