Check if location layer was changed. Yandex MapKit 3.0

How to check if i change camera location for disable anchor? I dont see solution in examples or docs.

I found the solution.

public class WorkFragment extends BaseFragment implements ..., CameraListener {
   @Override
   public void onCreate(){
   ...
   mapView.getMap().addCameraListener(this);
    ....
}

@Override
public void onCameraPositionChanged(Map map, CameraPosition cameraPosition, CameraUpdateSource cameraUpdateSource, boolean b) {
  if (cameraUpdateSource == CameraUpdateSource.GESTURES) {
    ...
  }
}
