    To draw on the display of a mobile device with Android you need a View, a Canvas, a Paint, and a Bitmap object. · The Bitmap is the physical drawing surface.Paint offers a rich set of coloring, drawing, and styling options.

    Even if only one app uses your view, that app needs to handle different screen sizes, multiple screen densities, and various aspect ratios in both portrait and landscape mode.
