问题
I have a service that basically manages a MediaPlayer instance for playing podcasts. Once an activity binds to the service it can do things like play, pause, stop, etc. I used a service because I want the podcast to continue playing even after the activity is destroyed.
I'd like the service to be able to send messages back to the activity in case of an error or for normal status updates. Is it possible for the service to get a reference to the activity that's trying to bind to it? Doesn't look like the intent makes this available.

The SDK samples API Demos app has an example of a service that messages back to an activity
