Remote android service keeps restarting
Ok, so I created an app that uses a remote service for real-time GPS tracking. I am using the below code to start and bind to a service.
The remote service uses helpl, sets the notification icon, starts the GPS and locationListener. In onLocationChanged, the handler sends data back to the caller via a callback. Almost straight from examples and resources on the Internet.
I want the service to keep running even if the application is closed. When the app reloads, I want the app to bind to the service again (using the existing service if it is running) and retrieve data from the tracker again.
I currently have the application mode set to singleTask and cannot use singleinstance due to another problem.
My problem is that quitting frequently even after the application and service are closed, either from the application itself, or from AdvancedTaskKiller or from Forceclose, the service restarts and initializes the GPS. touching the notification will open the app. I stop tracking again which removes the notification and disables the GPS app Close the app and again after a few seconds the service will restart. The only way to stop this is to turn off your phone.
What can I do to prevent this from happening. Is it related to the operating mode? START_NOT_STICKY or START_REDELIVER_INTENT? Or do I need to use stopSelf ()?
I understand that if a service is down when I use bindService (), that service will be created ... so do I really need to use start / stopService? I thought I would need to use it if I want the service to start even after the application is closed. This is why I do not disable / stop the service in onDestroy (). Is it correct?
I haven't seen any other information, so I'm not sure where to look.
Please, help! thanks patrick
