    Essential reference for Android Developers
    I gave this book 5 stars because it is very comprehensive and up to date as of pre-Kit-Kat. It does include Kit Kat materials online as an additional source though. I originally started learning android through the android developer site, but kept getting stuck due to lack of explanation for *why* things had to be done in a certain way. This book filled in the gaps by explaining the history of android and the reason why all the various APIs function the way they do. Great for understanding the platform.

    Has good background material
    Has good background material, supporting references and good developer tips like keeping the emulator open for the full session.The major problem I found with the book is that it does not cover Android Studio, only the Eclipse IDE. Much is the same between the 2 environments and you can understand the book’s walk thru examples, but not exactly.I’ve been using Code Project for my main training source with this book as a secondary reference. Currently they are having a 10K $ contest for experienced developers to write introductory articles on Android Development. The contest is producing a number of excellent articles that better fits my learn-by-doing style.

    Great book

    Where it all begins
    If you want a first book on android that is up to date, this is it. It explains every concept clearly and precisely to the point where the author would introduce to the topic just enough for you to understand the topic. It basically gives you a taste of what you can do with each major feature of android. I would highly recommend this to anyone new to android. If your intermediate or advanced and understand all of the basic concepts, you probably know everything presented already.

  5. Bill

    Excellent book and support from authors
    Let me tell you, not only this book is amazing, it is very thorough and detailed, but the authors are also excellent at helping you too, my app didn’t run correctly, I sent them an email, they replied the next day and helped me till my issue got fixed, specifically Joseph, he is one of the 3 people who wrote the book. You will regret if you don’t buy this book. Thank you

    this book seems pretty comprehensive and in many ways up to date
    From the first few chapters I’ve read, this book seems pretty comprehensive and in many ways up to date. I particularly appreciate the illustrations it offers which are a great tool for clarifying procedures. I’ recommend anyone; novice or professional to check this book out.

    unfortunately, the book is written to be used with Eclipse and with recent changes to the Android SDK it’s hard to get the code to run.Would have preferred using Android Studio

  8. Santos

    Outstanding material beyond mere introduction
    This book goes far beyond the breadth and depth that I would expect from an introductory book. Having developed on the Android platform for years, I still found valuable new material in this book.

  9. noel

    I got a knock off version of the book. It had 90 pages of what was meant to be something like 600. I don’t know whether Amazon has any quality check processes on their books or suppliers, I assume they do, although this time it passed through the net.

  10. D. Birkhead

    Great book but curiously, mine came with no print on the spine. I wonder if they’re all that way?
