As for the broadcast solution, can an Activity receive a broadcast while it is rotating? Will all the broadcasts sent to it be received?
About the Messenger, is it possible to create a Messenger from a Service to an Activity? In the Messenger tutorial, it says "it sends a Message to the service that includes the client's Messenger in the replyTo parameter of the send() method." It seems that the Service can only "reply to" a message from the Activity. Can a Service initiate a message and send to the Activity?
