Comment obtenir l'emplacement actuel dans MAPBOX sous Android

Comme j'utilise MAPBOX dans mon application.Je ne sais pas comment obtenir les lat et long actuels. J'ai utilisé cette méthode pour obtenir l'emplacement actuel.Mais sa référence d'objet null s'affiche.Veuillez m'aider à résoudre mon problème

     mapView = (MapView)view. findViewById(R.id.mapView);
    mapView.setStyleUrl(Style.MAPBOX_STREETS);
    mapView.onCreate(savedInstanceState);

    //Add a mapBoxMap
    mapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(MapboxMap mapboxMap) {
            mapboxMap.setMyLocationEnabled(true);
            // Set the Origin waypoint to the devices location
            Position Origin = Position.fromCoordinates(mapboxMap.getMyLocation().getLongitude(), mapboxMap.getMyLocation().getLatitude());

            Log.i("RR","mapboxMap.getMyLocation();"+Origin);
           // Log.i("RR","mapboxMap.getMyLocation();"+mapboxMap.getMyLocation().getLongitude());
            mapboxMap.getUiSettings().setZoomControlsEnabled(true);
            mapboxMap.getUiSettings().setZoomGesturesEnabled(true);
            mapboxMap.getUiSettings().setScrollGesturesEnabled(true);
            mapboxMap.getUiSettings().setAllGesturesEnabled(true);


        }

    });

mapboxMap.setMyLocationEnabled(true); a été deprecated.

Vous devez utiliser locationEngine pour obtenir lat et long comme ceci

    locationEngine = new LostLocationEngine(MainActivity.this);
    locationEngine.setPriority(LocationEnginePriority.HIGH_ACCURACY);
    locationEngine.setInterval(5000);
    locationEngine.activate();
    Location lastLocation = locationEngine.getLastLocation();

utiliser lastLocation.getLatitude(), lastLocation.getLongitude()
