This book is a collection of tutorials, walking you through developing Android applications, from the simplest “Hello, world!” to applications using many advanced Android APIs.

Also, the tutorials themselves have varying depth. Early on, there is more “hand-holding” to explain every bit of what needs to be done (e.g., classes to import). As the tutorials progress, some of the simpler Java bookkeeping steps are left out of the instructions – such as exhaustive lists of import statements – so the tutorials can focus on the Android aspects of the code.
