Android database programming : exploit the power of data-centric and data-driven Android applications with this practical tutorial / Jason Wei.

This book is a practical tutorial approaching the topic with clear instructions and examples. With easy to understand examples and scenarios you can apply almost anywhere, this book walks you through both local and external data storage methods for the Android platform. "Android Database Programming" targets developers who are experienced with databases and other back-end design concepts, but who may want to see these concepts applied to mobile applications. Developers who are experienced with mobile applications and/or the Android platform, but who may not be as familiar with back-end systems and designing/implementing database schemas will find this tutorial equally useful. Even if you are already experienced with both Android programming and database implementation, but want to further solidify concepts and see a broader scope of data storage methods on Android, this book is your perfect companion.
