Missing permission to manage media error on Android 5 / L

Question

Missing permission to manage media error on Android 5 / L

Get the following error on this line when trying to configure RemoteController. I could not find any information about this error, so I would like to post an error message and a simple solution.

The code that called it:

if(!((AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE)).registerRemoteController(mRemoteController)) {...} 

Mistake:

The user must explicitly grant your permission to access the notification application by going to Settings → Sound and notification → Access notification → Select the checkbox next to your application
