is it possible to write an app that is invoked by the phone ringing?
<p>I'm guessing the answer is no, but just in case, I'm curious if there's any way to write a receiver that would launch an app when the phone starts to receive a call.  Even something as simple as a dialog activity that says "your phone is ringing". Or is the phone always going to suppress any other app that's trying to run?</p>
