/* A note on the API being used. 2.2 introduces a new and sane API
* for handling multimedia button presses
* http://android-developers.blogspot.com/2010/06/allowing-applications-to-play-nicer.html
*
* the old API is flawed. It doesn't have management for
* concurrent media apps
*
* if multiple media apps are running
* probably all of them want to respond to media keys
*
* it's not clear which app wins, it depends on the
* priority set for the IntentFilter (see below)
