Hi

I am painting some bitmaps onto a transparent canvas, so it is rendered above the system screen.

When I draw the next bitmap, I cannot clear the previously drawn one. How can I "erase" it?

If I could capture the initial canvas would be fine...because I could paint always that before drawing the bitmap...but I am not succedding on capturing it.

Thanks!

Clear it with a paint which has it's alpha value set to 255. Won't that work?

No, I've tried it, that does nothing as it has it's maximum alpha, everything with that will be transparent.

Notice that everything that I paint paints above what was painted before, the canvas is not "refreshed", I need to erase what was drawn before or clear the canvas.

The example in the APIDemos do it rights by calling a method like OpenGlClass.clear(), I need that but in 2D.

Thanks!
