Overall, this book feels a little anaemic compared to what can be achieved under Android. The layout is a little odd too with chapters not always coming where you'd expect them to be. The final impression is of a reference book that assumes the reader is not only a coder, but one too busy to really go beyond the basic UI components provided as part of Android.
In fairness, writing a book for Android has to be like trying to hit a moving target so it is probably inevitable that parts of it will feel rushed or incomplete. Treat it as a reference, rather than a guide you can follow from start to finish, and it will serve adequately.
Or, rather, it would have done. This version only covers 1.0 and Android is now at 1.5.
