I have a media player which i want to mute when the user gets a call.
I was using the TelephonyManager to listen for calls creating the
listener on create and removing it on destroy in my service. like so:
public void onCreate() {
...
TelephonyManager tm = (TelephonyManager)getSystemService
(Context.TELEPHONY_SERVICE);
mcsl = new MediaServicePhoneStateListener();
tm.listen(mcsl, PhoneStateListener.LISTEN_CALL_STATE);
...
}
@Override
public void onDestroy() {
super.onDestroy();
...
TelephonyManager tm = (TelephonyManager)getSystemService
(Context.TELEPHONY_SERVICE);
tm.listen(mcsl, PhoneStateListener.LISTEN_NONE);
...
}
but when the phone rings i periodically get a crash in the ring app -
looks like when its trying to get the photo:

when i remove the listener the crash doesn't happen, looks like a bug
to me - but does anyone know of a workaround?
