Communicate with a started service
===

I'm trying to periodically capture image from camera using a service. To keep the service alive when the activity is paused/stop, I should start it as a started service - that's what I learned studying Service documentations (I'm a newbie trying to learn Android)

How do I communicate with the service? Say, I want to send some notifications to the activity (which started the service) when I've captured some photo from the service?

PS. I checked the answer http://stackoverflow.com/questions/2280845/how-does-a-service-communicate-with-its-activity-how-can-a-service-call-a-metho here but that's not that helpful.
