How to animate marker when it is added to map on Android?

Question

I want to animate map markers when they are added to map.

User should see the map with markers around him. Each new marker should bounce.

You can implement the onMarkerClick() and make the marker bounce whenever user clicks on it. Just try out below code implementation. I have tried it and it works totally fine.

 private Marker mPerth;  
 private Marker mPerth = mMap.addMarker(new MarkerOptions()
             .position(PERTH)
            .title("Perth")
            .snippet("Population: 1,738,800"));        

  @Override   
public boolean onMarkerClick(final Marker marker) 
  {
      // This causes the marker at Perth to bounce into position when it is clicked.
    if (marker.equals(mPerth)) {
        final Handler handler = new Handler();
        final long start = SystemClock.uptimeMillis();
        Projection proj = mMap.getProjection();
        Point startPoint = proj.toScreenLocation(PERTH);
        startPoint.offset(0, -100);
        final LatLng startLatLng = proj.fromScreenLocation(startPoint);
        final long duration = 1500;
        final Interpolator interpolator = new BounceInterpolator();
        handler.post(new Runnable() {
            @Override
            public void run() {
                long elapsed = SystemClock.uptimeMillis() - start;
                float t = interpolator.getInterpolation((float) elapsed / duration);
                double lng = t * PERTH.longitude + (1 - t) * startLatLng.longitude;
                double lat = t * PERTH.latitude + (1 - t) * startLatLng.latitude;
                marker.setPosition(new LatLng(lat, lng));
                if (t < 1.0) {
                    // Post again 16ms later.
                    handler.postDelayed(this, 16);
                }
            }
        });
    }
    // We return false to indicate that we have not consumed the event and that we wish
    // for the default behavior to occur (which is for the camera to move such that the
    // marker is centered and for the marker's info window to open, if it has one).
    return false;
}

You can also use this at the time of adding the marker in your application besides onClick event. I hope this what you want only.
