J2me screen flicker when switching between canvases?

I would say, that using multiple canvases is generally bad design. On some phones it will even crash. The best way would really be using one canvas with tracking state of the application.

And then in paint method you would have.

If the device itself does not support double buffering you should define a off screen buffer (Image) and paint to it first and then paint the end result to the real screen. Do this for each of your canvases. Here is an example.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
