I agree with @Ovidiu Latcu but with one important note: when using bound services, the service is ended when the activity that started it is ended, (if it is the only activity bound to that service).

So if you want to run your service at the background while the app is in the background, (the activity is paused for example and not visible to the user) then you must start the service without bounding to it and communicate with it with BroadcastReceiver for example.
