About the Book

Learning a new language is exciting. It opens up a world of possibilities that were not available before.

In the case of Android and Kotlin, this is especially true. Thanks to the features of the language, you can change the way you solve your problems and become way more productive.

In this set of guides I show you how to make use of this features in your day to day projects:

  1. Anko: Learn how to create views using this powerful DSL instead of XMLs
  2. Kotlin DSL: Improve the way Gradle files are written and make them easy to modify thanks to the use of Kotlin instead of Groovy.
  3. Coroutines: Learn some of the basic of the coroutines and convert your asynchronous code to synchronous style
  4. Kotlin Android Extensions: Forget about findViewById and improve your code readability by drastically reducing the number of lines of code.
  5. Java Interoperability: Discover how all the new features of the Kotlin language interact with Java, where are the limits, and how it can help you with your current Java projects.
