Android Studio

All Android Studio's existing tools work with Kotlin code. We can easily use debugging, lint checks, have proper code assistance, refactoring, and more. Most of the things work the same way as for Java, so the biggest noticeable change is the Kotlin language syntax. All we need to do is to configure Kotlin in the project.

Android applications have multiple entry points (different intents can start different components in the application) and require Android framework dependencies. To run the book examples, we need to extend the Activity class and place code there.
