android - GoogleMaps GroundOverlay blinks my images -

-

i'm using googlemaps in android app, , want display animated radar image on map.
have array of 6 bitmaps. when user hits play, map loops through displaying each of images on map.

this working, when transitioning between images, if don't call googlemap.clear(), images continually stacked on top of each other.
if call googlemap.clear(), horrible blink. want 1 image remain on map until next 1 displayed.
there way this?

is there maybe double-buffering option googlemaps?

oh, actually, ended doing extending googlemap class , overriding ondraw function liking.
