title: (Android) How to catch a "ring" event?
body: <p>I'm clearly a newb, and I was wondering if anyone knows how I can detect a "ring" event on my cellphone through the android sdk?  Generally I want to do something with the phone when it begins ringing!  Any thoughts?</p>
  
  <p>If you want to simply point me to a page in the api documents that would be a good answer for me, I just don't know how to start my research!</p>
