Preface

Android is the most popular platform for mobile devices. Every year, there are more and more developers getting involved in Android development. The Android Framework makes it possible to develop applications for mobile phones, tablets, televisions, and much more! So far, all development has been done in Java. Recently, Google announced Kotlin as the second language developers can use. Because of this, and with Kotlin's ever-growing popularity, we decided to introduce you to Android using Kotlin as its primary development programming language.

With Kotlin, you can do everything you can do with Java, but with more joy and fun! We will show you how to play with Android and Kotlin, and how to create amazing things! Thanks to Kotlin, it's certain that the Android platform will evolve even more. In the near future, it's not impossible that Kotlin will become the primary development language for the platform. Take your seat and get ready for a great journey!
