Hi Dianne - yup knocking up a wee pacman game to learn android.... what gave it away? :)
I was using standard drawables until I hit the issue of animating the drawables. Thats when I started looking at ImageViews. It was my understanding that I had to use an ImageView to achieve frame-by-frame animation. Can it be done without ImageViews? Are there any examples that I could look over?
