Apparently the framework in this book is is a simplified version of the libgdx game framework so if you like the content of the book, check out libgdx. Even if you don't decide to develop libgdx, it is worth getting to know the framework for general knowledge and future understanding of other frameworks. No knowledge goes to waste if it can be used.
Note that the game framework uses Activities and Assets exclusively and not Fragments and Resources. If that doesn't mean anything to you, go read a beginner book on Android programming before tackling this one.
This is an intermediate to advanced level book, not for beginners.
