Like Tom said: Create a bitmap, like in your example. - Create a mutable bitmap that is a copy of your original (Bitmap.copy (...)). - Wrap a canvas around this new mutable bitmap (new Canvas(bmCopy)) - Just draw on this canvas. - After each draw on this canvas, your bmCopy will be updated.
If you don't have an original bitmap, but an original Drawable instead, get the width and height of the drawable and create a mutable (but empty) bitmap from that: - Create a mutable bitmap that is the size of your drawable: Bitmap.createBitmap(width, heigh, config); - Wrap a canvas around this new mutable bitmap (canvas = new Canvas (bitmap)) - Draw your original Drawable on this canvas (origDrawable.draw (canvas)). - Just draw other stuff on this canvas. - After each draw on this canvas, your bitmap will be updated.
