Last week while conducting the summer training on Android & Java, one guy requested me to help develop an Android game. I thought the bouncing ball would be the perfect example through which we can show about Android graphics and animation. However, i would strongly suggest to use professionals Game engines like cocos-2d to develop real life Game apps.

This app is  simple yet will be able to clarify many things related to android graphics to the students. I have made this game opensource and one can clone the source code from the following link.

Here is a screen recording of this app.

If this helps the Android learners, i would probably be the happiest guy.
