How to stop location manager?

Don't know why, but sometimes LocationManager is still working also after closing application.

I call startGPS() in onCreate-Methode in one Activity (only one, let me call it StartActivity).

protected void startGPS(){    
 try {           
     lmanager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
     lmanager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
     lmanager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
 } catch(Exception e) {
     e.printStackTrace();
 }
}

And if this activity will be destroyed (so, when application will be closed), I call endGPS()

public void endGPS(){
 try {           
     lmanager.removeUpdates(this);
     lmanager=null;
 } catch(Exception e) {
  e.printStackTrace();
 }
}

Some ideas, some suggestions, what have I done wrong?!

Quite an old queerie but this works for me.

       @Override
        public void onStatusChanged(String s, int i, Bundle bundle) {

        mLocationManager.removeUpdates(locationListener);

        }

I use: locationManager.removeUpdates(locationListener); Its Working

    @Override
protected void onPause() {
    super.onPause();
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }


    locationManager.removeUpdates(locationListener);
}

You should call the method removeUpdates inside the method onPause:

@Override
protected void onPause() {
    super.onPause();
    locationManager.removeUpdates(this);
    Log.i(TAG, "onPause, done");
}

Is it possible your activity isn't being destroyed? i.e.: you hit the home button. Move your gps start/stop to onStart and onPause.

I see it´s been a while since this post, but maybe it would help some body else. I use: removeUpdates(this), because my listener it´s the activity where I implement de location manager, you need to indicate your listener.

The emulator never gets rid of the GPS icon once loaded. Hence, on an emulator, you cannot use the GPS icon as a test as to whether GPS is still running. On a device, though, the icon should vanish.

Should I use two different listeners?

I sure would. I do not know whether removeUpdates() will remove both, or even if both requests are registered with the single listener.
