Android draw with blur

Question

Hi, I need do draw on Android's Canvas using Blur effect, it is a very simple feature, I need to draw a circular area, which is blurred (the foreground) and the background transparent, I can do everything with manipulating the colour alpha to do it with custom transparency but I need it to be blurred instead of transparent.. any ideas?

If you're not gonna need to manipulate it afterwards you could just draw to a buffer and blur it yourself pixel by pixel, then blit that buffer to screen when you need to paint it.
