i want to show the location indicator when the map is loaded and add a marker whenever the map is clicked but none of these seem to work !

protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);


 final MapFragment mapFragment = (MapFragment) getSupportFragmentManager().findFragmentById(R.id.mapFragment);
 assert mapFragment != null;
 mapFragment.getMapAsync(new OnMapInitListener() 
 @Override
 public void onMapReady(MapView mapView) 
 OnlineManager.getInstance().enableOnlineMapStreaming(true);
 PositionManager.getInstance().startPositionUpdating();
 PositionManager.getInstance().enableRemotePositioningService();
 mpView=mapView;

 mpView.addMapGestureListener(new MapGestureAdapter() 

 @Override
 public boolean onMapClicked(final MotionEvent e, final boolean isTwoFingers) 

 MapMarker marker = new MapMarker(new GeoCoordinates(PositionManager.getInstance().getLastKnownPosition().getLongitudeAccuracy(),PositionManager.getInstance().getLastKnownPosition().getLatitudeAccuracy()));
 mpView.addMapObject(marker);
 return true;
 
 );

 

 @Override
 public void onMapError(int error, String info) 
 );

 

You’re trying to create new Marker with getLongitudeAccuracy() and getLatitudeAccuracy(). You need to use geo coordinates!

If you want to add the marker to the position of last known gps signal you can use this code:
MapMarker marker = new MapMarker(PositionManager.getInstance().getLastKnownPosition().getCoordinates())

But as there can be no known position at that time it can result in no marker added. So be sure you have location turned on and strong signal. Based on your example it would make more sense to add marker to the position you clicked on. For that purpose use this code:

 mpView.addMapGestureListener(new MapGestureAdapter() 

 @Override
 public boolean onMapClicked(final MotionEvent e, final boolean isTwoFingers) 

 MapMarker marker = new MapMarker(mpView.geoCoordinatesFromPoint(e.getX(), e.getY()));
 mpView.addMapObject(marker);
 return true;
 
 );
