Well, it would sure help if you didn't assassinate the process the service is running in! You do not want to call System.exit().
Now, one thing to realize about Android is that processes are killed when not needed -- or sometimes even when needed -- and then restarted later, re-creating the object as needed. Since Android components (services, activities, etc.) share the same process, it's up to Android to figure out when it's appropriate to kill the process; that's why you should not call System.exit().; If you'd like a service to get recreated, you'll need to start the service using Context.startService(Intent) , as you appear to be doing, and then in the service's onStartCommand(Intent, int, int) method, return Service.START_STICKY, or Service.START_REDLIVER_INTENT. Then so long as the service hasn't been stopped, if the process with the service gets killed or crashes, it will be restarted by the system. Now, you say you want to make sure the service runs indefinitely. I hope you don't mean that too literally -- as in keeping the CPU running. Your service should only actually run in response to specific events. These can include timer events, but you want to keep any activity to a minimum. In fact, you'd like to have the service stop, and the process be allowed to be deleted, if there's a way. If there's a broadcast intent that you can listen for, you can set up a broadcast receiver, and start your service from that, and then when the work is done, have the service stop itself. This will reduce how much impact your service has on the system and make your application a lot more friendly. Unfortunately, that's not always an option.
