Until now, we have been using standard views and translating them to render the different elements of the game. While this is an easy way to draw elements on the screen, it is far from being efficient. We are relying on the system layout to do the drawing.

While this technique is fine for a turn-based game or any non-real-time game in general, it cannot render enough frames per second for a real-time game.

We already noted the duplication of code and mentioned the concept of sprite in the previous chapter. We will now move forward and create a Sprite class that will take care of drawing an image at specific coordinates inside the GameView.

There are two ways of drawing at low level on Android. They are:
