Author: Wei-Meng Lee
Publisher: Wrox

Format: Paperback


So, what does the book actually cover? Well, quite a lot as it so happens. I was particularly impressed that the author covered topics such as geocoding and reverse geocoding, which at the time was somewhat difficult to find good examples of. As well as how to get going with developing for Android 4, the author also covers how to publish your application once it's complete - from digitally signing it to publishing it on the app market, so pretty much all the basics are covered.

The following chapter list will give you an idea of what topics made it into the book with a very brief breakdown of each chapter.

General Impressions

I initially found this book whilst browsing through my local bookshop here in Dublin on a rare day off from work. The book was one of the first that I had found that dealt with the then new Android 4 SDK and initial glance seemed to be different enough, and helpful enough, to warrant a purchase.

I was pleasantly surprised once I got home to find out that I was correct. The book delves into the usual pleasantries such as getting started with Android development before dealing with the juicier stuff. As it's an older book (by comparison) at this point, don't expect there to be any reference to the newer Android Studio (which admittedly is still considered to be 'Early Access' - but I'd bet money that Google will eventually drop Eclipse support once this product is well established and has useful things like all the necessary menus built) but there's a nice summary of how to set up the SDK, Eclipse and ADT to get the most unfamiliar of you up and running with Android development.

Once these pleasantries are out of the way the book dives into the basics of Android, starting with the ubiquitous Activity. Straight away the style of this book becomes evident, the author tells you "Here's what we're going to do", gives the code for it and then sums everything up in a nice post-mortem after the code has been presented. As each example and subsequent post-mortem progresses, the author builds upon each previous notion in a way that minimises repetition while maximizing learning and experience. As with any good book, at the end of each chapter you'll find a summary of what was covered in the chapter and what you ought to have learned.

So, all-in-all, pretty good right? Well, yes and no. The author does a pretty good job of covering the basics and for an amateur programmer or someone completely new to Android programming, it will probably be enough. I personally found myself wanting a little bit more in places, such as the section for sending / receiving SMS messages. Yes, he does cover these topics in Chapter 8 (Messaging) but there is no reference on how to interact with messages already on the device. I suspect this is not so much an oversight as the fact that Android provides no formal API for dealing with SMS/MMS messages that are stored already, and getting into how to do this involves a complexity a little too high for the average newcomer but it just seemed to be a cop out not to address it at all.

That gripe aside, this book does generally do an awesome job at what it set out to do - teach you how to get going with Android 4 Application Development.


As Android development books go this is a great place to start. You're helped to get up and running (only with Eclipse, this was written pre-Android studio) and gently introduced to the various core aspects of Android and what it means to program for it. Building upon what you've learned in each chapter, you'll be impressed with what you can do by the end of it. It doesn't answer all of the questions you'll have though and, while I suspect newcomers to programming for Android will find it to be a good reference for a while, you'll also find yourself more and more often looking for that little bit more. A reference book this it not though but, fear not, there are plenty of good references out there for you.


With the caveats of this book NOT being for professionals AND being a little dated now, I'd rate it 4.5/5 - you'll find it to be a great starting place and a natural stepping stone to bigger and bolder Android concepts and techniques.

Thanks for reading!
