This book gives a good understanding of components of an Android app, current state of development ecosystem (e.g., how half-baked Fragments are, when you try to use them with MapView or other fragment-related activities), and provides a good overview of decisions behind those components (why use data providers, why rely on asynchronous services, how to write properly updating Internet-connected applications).
All chapters (and there are 49 of them) follow pretty much the same pattern - introduction into the problem, explanation of how the problem can be resolved in Android, as well as sample app that solves that specific problem. This makes the book more of a reference title, as chapters could be read out of sequence (although if you're new to Android, it makes sense to cover the first few parts in sequence).
Both Java and XML are pretty verbose, so author makes a decent attempt to cut down on the boilerplate code and concentrate on what matters.
