Whatever your Android programming level is, this book is a complete waste of time and definitely doesn't worth a single penny. After reading half of the book it was very clear to me that there is no leading author for this book and nobody technically reviewed the book as a whole. Except chapter 7, referring to signing and publishing Android application, the whole part one is useless. Whole Android installation process is different right now and you better check Google web site to get latest installation steps. Not to mention that there are unnecessary and very annoying repetitions on how to use Eclipse.
Even if first part was disastrous, I did finish the book. In second part there are two chapters that are worth spending your time on: chapter 10: Building a View and chapter 13: Inter-process Communication. As for the rest....utterly disappointing. The authors even prove that they don't know what application they wrote. In some chapters they use different names for same class they put in their application, this in addition to the fact that their application doesn't work at all.
If you receive this book as a present and you are completely bored you can read it, otherwise I would not spend a single penny on it.
