Alex, even if you use register / remove in onResume() / onPause(),
you're saying you still see the GPS icon get stuck on the notification
bar, unless you set your interval rate to something less than 35
seconds?:
@Override
protected void onPause() {
super.onPause();
locationManager.removeUpdates(this);
}
@Override
protected void onResume() {
super.onResume();
locationManager.requestLocationUpdates(...);
}
I made a test app with the above structure, and sometimes the GPS icon
will still get stuck on the notification bar. I'm using an interval of
two minutes. I wonder if I have to set it to < 35 seconds to get this
to stop? What a pain.
Thanks
