I followed this tutorial http://code.tutsplus.com/tutorials/create-a-music-player-on-android-user-controls--mobile-22787 to build an audio player.
All works fine, but my MediaController behave oddly. In fact the controller's seekbar does not update until the user interacts with it.
I tested with API 16 to 19 without success, i have the same problem.
I tested many solution on topics i found on stackoverflow without success also.
Has anyone an idea?
