Question

I’d like to include a simple draw feature on my app. A friend told me I can’t use canvas because I need to control the frame buffer and not redraw the entire screen every for every frame. He suggested I find a openGL 2d engine. I’ve searched around and I’ve only found Rokon which doesn’t have any documentation and the examples aren’t quite what I need.

Any suggestions?

I don’t really understand what the problem is?
If you simply wish to redraw some portion of the canvas you can use invalidate(rect).
