The words on the book "Get started with game apps development for the Android platform" is misleading because the book does not cover the Android API. I checked the forum on the author's site and found out that the reason for not covering the Android API is that this API is not platform independent. So why the words "Android platform" on the book? Shouldn't the cover simply state "Creating a Java framework for beginning Android Games" because that's what the book is about.
Later, in the book, I read that he wanted to make things easier by not covering the Android API. But it is truly easier to learn how to do things the correct way than to learn the "easier" way and have to relearn everything. Plus, this book is listed second in Apress's Android book series, right after the beginning Android book; so one should already have some knowledge of the Android API before ready this book.
In reality, the book is a precursor to the open source Java-based game development framework libgdx, which the author developed. This framework works on Windows, Linux, Mac OS X, as well as Android. Thus, the reason for the code not being platform dependent and, therefore, not using the Android API. The book should not be sold as an Android book. It is a Java framework that just happens to work on the Android. This does not mean it is the best way to write code if you are creating your games solely for Android devices. Otherwise, why even bother to develop the Android API?
As a book that provides a Java framework for creating games for Android mobile phones, the book is excellent. The author's framework provides a very organized structure for creating games.
However, there will be issues that will crop up if you use his framework without the Android API. For this reason, I am now in the process of modifying the code to use the Android API, at first I subtracted one star, giving the book four stars instead of five, for that. But after reading Chapter 6 and realizing just how uncompilable his code is to the Android way of doing things, I've subtracted two stars.
