LocalService

public class LocalService extends android.app.Service
This is an example of implementing an application service that runs locally in the same process as the application. The {@link LocalServiceController} and {@link LocalServiceBinding} classes show how to interact with the service.

Notice the use of the {@link NotificationManager} when interesting things happen in the service. This is generally how background services should interact with the user, rather than doing something more disruptive such as calling startActivity().
