LocationListener dengan Geocoded Toast tidak berhenti setelah aktivitas keluar dari OnCreate

Saya memiliki locationListener sederhana yang hanya menggunakan GPS untuk memulai. Di dalam OnLocationChanged saya melakukan pencarian geocode dan menampilkan pesan Toast. Soalnya setelah aktivitas tidak lagi di depan gps masih menerima update dan memproses Toasto. Saya memiliki RemoveUpdates di onStart, onPause, onDestroy dan onStop.

Adakah yang tahu mengapa saya tidak bisa menghentikan layanan ini?

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mapView = (MapView) findViewById(R.id.mapView);
    mc = mapView.getController();

    locationListener = new GPSLocationListener(); 
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);           
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,locationListener);    

...
...       

public void onStart(Bundle savedInstanceState) {
    locationManager.removeUpdates(locationListener);
    locationManager=null;
}

public void onPause(Bundle savedInstanceState) {
    locationManager.removeUpdates(locationListener);
    locationManager=null;
}

public void onDestroy(Bundle savedInstanceState) {
    locationManager.removeUpdates(locationListener);
    locationManager=null;
}

public void onStop(Bundle savedInstanceState) {
    locationManager.removeUpdates(locationListener);
    locationManager=null;
}

class GPSLocationListener implements LocationListener {     
    @Override
    public void onLocationChanged(Location location) {
        if (location != null) {

          current_heading=location.getBearing();
          String current_bearing = headingToString2(location.getBearing());

          point = new GeoPoint(
              (int) (location.getLatitude() * 1E6), 
              (int) (location.getLongitude() * 1E6));

          // add marker
          MapOverlay mapOverlay = new MapOverlay();
          mapOverlay.setPointToDraw(point);
          List<Overlay> listOfOverlays = mapView.getOverlays();
          listOfOverlays.clear();
          listOfOverlays.add(mapOverlay);

          mapView.setStreetView(showStreet);
          // enable to show Satellite view
          mapView.setSatellite(showSatellite);        
          // enable to show Traffic on map
          mapView.setTraffic(showTraffic);        
          mapView.setBuiltInZoomControls(true);

          mc.animateTo(point);
          mc.setZoom(16);

          address = ConvertPointToLocation(point);
          Toast.makeText(getBaseContext(), address, Toast.LENGTH_LONG).show();
          Toast.makeText(getBaseContext(), address, Toast.LENGTH_LONG).cancel();
          }     
    } 

Ini LogCat saat mencoba pulang
