This book and the series are probably the best books out there.

Pro Android 3 by Sayed Hashimi

This is the third Android programming book I have read and so far it is the best.
This book is well written, logically laid out, and has downloadable projects.
This book is crazy big, packed full of info.
The authors explain in exceptional detail the topics covered and all important topics are covered.
It seems like a great book for me;
The book has an extensive description, it gives a good base for understanding key concepts of Android 3 and start programming apps for this great platform.

Excellent work and I will definitely recommend it to everyone who asks me how to do the Android thing. 😉
The book is great! If you're a beginner, this book is a must... BUT... it will not walk you through the building of any apps.
I found this book very informative. It covers almost all aspects of core Android 4, emphasizing best practices.
This is just an exceptional book. It is easy to understand, yet very thorough.
This is a great book to learn android development.
Progressive examples do a good job of explaining various areas of programming for an Android device.
This is an excellent book. It covers all the topics you need, it works progressively, the examples all work, and it gives pointers for further information.
This book offers really complete coverage of the Android development process.

I absolutely recommend this book to anyone just beginning to dip their toes into the Android waters.
I like the style of this book. The worked example is usually a winning format, and this is no exception.
It's a good place to start, it provides some useful examples to introduce you to the Android developer role.
Great book, filled with an array of case by case examples with in-depth explanations.
This is an excellent book for the absolute beginner but this does not do justice to the depth and breadth of the contents.
