@cundong could not obverse that problem on my note 4(my device) and nexus 4(Genymotion). Is shake so visible? And can you tell me which device you are running?

onDraw method rotates canvas, draws cover and rotate it back to 0 degree to draw button, progress etc. I know it is little tricky but it was not visible to me.

I think，perhaps there is a better solution than "roate a canvas". but i have no good idea now.

Exactly, as I said it is little tricky. I didnt think that it will be visible by people. I did not know what is solution but I know that always there is a better solution :) thanks.
