Animation on top of MapField in Blackberry

I am using blackberry maps to write my Application and want to show current location of the user on the map using a Blue dot image. I am able to do it by overriding the paint() method of the MapField and place the image at the right place.

However now I want to pulsate开发者_开发百科(breathing bubble) the image, for that I am using a gif image with 3 different frames. Here i am not sure how to display all the 3 frames at certain frame rate so that I don't have to rely upon mapfield.paint() to draw my images. Initially I thought of using AnimatedGifField's thread for this, but not sure how to using it coz i can't add a field(AnimatedGifField) to a field(MapField). I am using JDE 6.0

Does anyone has any idea about it..?

I would probably just keep using the paint() method, but when you need to redraw the bubble, invalidate a region instead of invalidating the entire screen. This will allow you to continue using the paint method without needing to have the entire thing redraw itself.
