This question concerns the phone's GPS hardware remain on (and therefore draining the battery). I'm looking for advice for preventing this.
My app starts a service which starts the GPS. The intention is to have the service run for a long time occasionally using FTP to post the phone's co-ordinates to a server.
After a while the app is killed by the OS but the service continues (occasionally restarted using the StartServiceAt command).
When the GPS returns a location (myGPS_LocationChanged) the location is FTPed and then the GPS object is stopped. Some time later (on a timer) the GPS object is restarted, location co-ordinates are read and FTPed - then the GPS is stopped again.
This issue is that after a long time (often days) I find that the GPS status icon is permanently present in the phone's status bar. I restart the app (which presumably kills and restarts the service) and the GPS status icon reverts to its expected mode of appearing for a second or so and then disappearing - repeating this every minute or so depending on my timer parameters.
What is causing the GPS hardware to stay on? I assume the GPS object would be stopped and killed if the OS kills the service - so therefore the service must still be running. What would be the best way of ensuring that the GPS hardware is only on when it needs to be?
