Add Animation on map marker android

This is the source code from stackoverflow. I save in my blog for my reference..

1. 

TranslateAnimation animation = new TranslateAnimation(0.0f, 400.0f,0.0f, 0.0f);
//new TranslateAnimation(xFrom,xTo, yFrom,yTo)

animation.setDuration(2000);  // animation duration 
animation.setRepeatCount(100);  // animation repeat count (total repetition)
animation.setRepeatMode(2);   // repeat animation (left to right, right to left )
//animation.setFillAfter(true);      

img_animation.startAnimation(animation);

and

2. 

BitmapDescriptor icon = BitmapDescriptorFactory.fromResource(R.drawable.current_position_tennis_ball)


        MarkerOptions markerOptions = new MarkerOptions().position(latLng)
                 .title("Current Location")
                 .snippet("Thinking of finding some thing...")
                 .icon(icon);

        mMarker = googleMap.addMarker(markerOptions);
