title: Is it possible to react to headphone volume up/down keys in an Android application?
body: <p>I want to know if it is actually possible to react to headphone volume control buttons in an Android application. Whenever I use iPhone/iPod supported headphones, I can use the pause/forward/rewind button with various music apps but NONE of them can react to the volume control.</p>
  
  <p>I've searched a lot and haven't found anything that addresses this issue directly.</p>
  
  <p>I am curious whether this is a limitation on the Android platform or on the apps that I am using. If its not a limitation, how would I capture the volume rocker events from the headphones in my own Android application.</p>
  
  <p>iPhone/iPod seem to be able to react to all headphone events through the 3.5mm jack. It seems to me it should be possible in Android as well.</p>
