The book is written in a cookbook style, presenting examples in the style of recipes, allowing you to go directly to your topic of interest, or follow topics throughout a chapter to gain in-depth knowledge. If you are new to Android application development and looking for a quick start, or if you are an experienced Android developer looking for a reference guide, then this book is for you. Ideally, you should know some Java and a little about mark-up languages but this is by no means necessary. This book will teach you how to write rich Android applications from scratch in no time.
