I really recommend not using a broadcast receiver for this. Generally this kind of thing is a 1:1 communication between the service and a client. It semantically isn't a broadcast it is sending to the world.
Instead, follow the LocalService example and just do the normal Java implementation of adding a callback that the service calls. Unless you are very careful, a broadcast receiver can open up a number of security holes in your app -- any other app could receiver the broadcasts you are sending, any other app could send broadcasts to you. You can prevent this from happening with careful use of permissions, but why bother? Just do a direct callback from the service to the client.
