title: Finishing an Activity from a Broadcast Receiver
body: <p>I have an Activity that I display as modeless when the phone rings (over the phone app). I would like to finish the Activity when either of the following events occur. The first is if I touch anywhere outside the Activity (this is not a problem), the second is if the ringing stops. I am listening for IDLE_STATE in the broadcast receiver but I am not sure on how to call the finish on the activity when I see it. The receiver is not registered by the activity but by the Manifest.xml</p>
