title: Droid Incredible Headphones Detection
body: <p>I'm developing an Android application for the Droid Incredible.  When I plug in my headphones, an icon appears on the status bar, so I presume the phone must know headphones are present.</p>
  
  <p>My code produces beeps in response to various user inputs, but I discovered today that's a REALLY BAD idea when the user is wearing headphones.   Ow.</p>
  
  <p>Does anybody have suggestions for how I can detect the presence of headphones programmatically, in Android??</p>
  
  <p>Thanks,
  R.</p>
