Answer 1

Marker marker;//have a instance variable marker
mMap.setOnCameraChangeListener(new OnCameraChangeListener();
public void onCameraChange(CameraPosition cameraPosition) {   
                MarkerOptions options = new MarkerOptions()
                                        .position(cameraPosition.target);

                 if(marker != null){marker.remove();}
                 marker = mMap.addMarker(options);
}

This won't be smooth because,onCameraChange call back is not called during intermediate frames.It is called only after the camera is changed completely.
