I really wanted to like this book more - at times the information is really good, like the "working in the background" section. However most of the book feels like bits and pieces were cut and pasted into place. Thus author seems to repeat himself often, especially early on. What's worse, the repetition doesn't reinforce any major points of the platform either. I'm left guessing that the book was rushed to print before it was fully edited.
There is some good information here though. And this gives a solid glossing over many of the major themes of Android - which makes this a decent compendium. So if you are looking for an overview of simple GUI development, general, small applications, and some talk about background processes and communications and some of the hardware you could do a lot worse.
However, you could also go to the Android development website and get the same information there as well.
An excellent set of information, but not well organized for experienced programmer and not clear enough for a beginner. If you are new to Android AND Java, you are better served with a Java Programming book first. This is also for Android 1.x and is now supplanted by version 2.X
