developer, whether an Android newbie or a seasoned Android developer who used to work on ADT, will find this book useful for developing his or her knowledge of the tools that are actually there to support his or her coding skills.

      Quoting Alex Theedom, co-author of my previous book: “Every chapter that we wrote has this goal: Write content that we would like to read ourselves.” We followed the same goal with Onur and the result is the book you are holding in your hands.

      We hope that you enjoy reading this book as much as we enjoyed writing it.
