Since this was brought back up ... this worked for me as well for the Cliq (original issue).
Also, FYI, I found that an easier way to get the distance for the circle radius is to simply use Projection.metersToEquatorPixels(float), which converts a distance in meters to pixel units. I also added simple animation to more closely match the default implementation by simply alternating which Drawable is used in the draw() call every half second or so.
