Canvas.getWidth/getHeight() return the size of the Canvas. The dimension of the Canvas is decided by the caller of your draw() method. It would be legitimate for instance for every View to use a different Canvas (which is actually what happens when hardware acceleration is enabled.)
The dimensions you should care about are View.getWidth/getHeight and Canvas.getClipBounds.
