}
music plays well but when i backpress on device its stop music. My Problem is i want to keep playing music in background if user presses hardware backbutton.
Any help will appreciate Thanks
You are unbinding from the service in onDestroyView. When the last ServiceConnection is unbound, the onUnbind method is called on the Service. Your onUnbind implementation stops playback. Instead you should include playback controls in your foreground notification and control playback via PendingIntents that are directed at your Service class.
