How to update Circle object on the Google Map?

In my app, I am displaying a circle around the user. When the user moves, the circle has to move accordingly. Right now to perform that task, I am calling the following function in the onLocationChange method:

public void drawCircleOnMap(GoogleMap googleMap, double lat, double lng) {
    if(circle != null) {
        circle.remove();
    }
    circle = googleMap.addCircle(new CircleOptions().center(new LatLng(lat, lng)).radius(CIRCLE_RADIUS)
    .fillColor(Color.argb(100,88, 214, 141)).strokeColor(Color.GREEN));
}

However, the problem is, after every update, the circle keeps blinking. I guess deleting itself and then creating a new one. What is the best way to make it go smother?

You just need to set center property only not remove and draw circle again on position update just set center property like below

circle.setCenter(newlatlng)
