You simply can not do this. A BroadcastReceiver component only "lives" for the duration of the call to onReceiveIntent(); it is not allowed to use registerReceiver in it, because by the time you return from that method (at which point you could first receive anything from your register), the component is no longer alive, and the system could kill at any time to reclaim memory.
