I'm working on an Android project and the application needs the GPS coordinates to work.

So after a long sleep, the line of code below give me null when I try to get the coordinates

locationManager = (LocationManager)getApplicationContext().getSystemService(LOCATION_SERVICE);
Location _lastLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

So to get them, I've to start Google Maps which is a little bit disapointing . I already read a lot of threads but anyone really helpful. I'm using a Samsung S2 and a S3 but I also read that the cause is a bug in the native service which stuck in a loop trying to restart itslef.

Is anybody know how can I figure this out?
