Introduction

Welcome to Advanced Android 4 Games . This book will help you create great games for the

Android platform. There are plenty of books out there that tackle this subject, but only this book

gives you a unique perspective by showing you how easy it is to bring native PC games to the

platform with minimum effort. This is done using real-world examples and source code in each

chapter. Keep in mind that before you dig into this book, you will need a solid foundation in Java

and ANSI C. I have tried to clearly and simply explain the most complicated concepts with a

combination of graphics and sample code. The source code provided for each chapter will help

you understand the concepts in detail and make the most of your time as a mobile game

developer.

The Green Robot Has Taken Off

It is hard to believe that is has been just two years since Android came onto the smartphone

scene; and it has taken off with a vengeance. Take a look at the US smartphone platform market

share, shown in Figure 1, according to a survey by Nielsen. 1 In May 2011, Android commanded 36

percent of the smartphone market in the United States—not too shabby for a two-year-old OS.

And the stats just keep getting better and better. Distimo, an analytics company specializing in

app stores, forecasted that Android Market would surpass Apple’s App Store in size by August

2011. 2 This opens a new frontier for developers looking to capitalize from the rocketing

smartphone segment. Advanced Android 4 Games is just what you need to get running quickly in

building cutting-edge games for the platform.
