== Obtaining Results from a Broadcast ==

When a broadcast intent is sent using the sendBroadcast() method, there is no way for the initiating activity to receive results from any broadcast receivers that pick up the broadcast. In the event that return results are required, it is necessary to use the sendOrderedBroadcast() method instead. When a broadcast intent is sent using this method, it is delivered in sequential order to each broadcast receiver with a registered interest.
