LocationListener mit geocodiertem Toast, der nicht aufhört, sobald die Aktivität "OnCreate" verlässt

Question

Ich habe einen einfachen locationListener, der GPS nur zum Starten verwendet. Inside OnLocationChanged Ich mache eine Geocode-Suche und zeige eine Toast-Nachricht an. Das Problem ist, sobald die Aktivität nicht mehr im Vordergrund ist, erhält das GPS noch Updates und verarbeitet den Toasto. Ich habe RemoveUpdates in onStart, onPause, onDestroy und onStop.

Irgendeine Idee, warum ich diesen Dienst nicht stoppen kann?

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(); 
      }  
    } 

Hier ist die LogCat, wenn zu Hause

Answer 1

Sie sind nicht alle Methoden überschreiben zu gehen versuchen.

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; 
} 

Das sind nicht die Methodensignaturen für diese Methoden. Es sollte

@Override 
protected void onStart(){ 

} 

etc

Sie sollte dem Hinzufügen der @Override Anmerkung zu Methoden gewöhnen, die Sie überschreiben
