Answer 1

OnLocationChanged Methodenaufruf in regelmäßigen Abständen dies der Grund ist. Entferne diese Zeile.

map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(dLatitude, dLongitude), 14));

@Override 
public void onLocationChanged(Location location) { 
    mLastLocation = location; 

    //remove previous current location Marker 
    if (marker != null){ 
     marker.remove(); 
    } 
    double dLatitude = mLastLocation.getLatitude(); 
    double dLongitude = mLastLocation.getLongitude(); 
    marker = map.addMarker(new MarkerOptions().position(new LatLng(dLatitude, dLongitude)) 
      .title("My Location").icon(BitmapDescriptorFactory 
        .defaultMarker(BitmapDescriptorFactory.HUE_RED))); 

}
