Android applications are widening their rank of influence to new devices such as digital pads, embedded systems, Google Glass, or Wearable. This book is intended as a guide for those readers who want to be introduced to Android programming. All the sections are accompanied by easy-to-follow examples, increasing in the level of complexity as they progress through the book. This book is recommended to both non-experienced users and programming experts.
