Android Studio provides full support for Kotlin, enabling you to add Kotlin files to your existing project and convert Java language code to Kotlin. You can then use all of Android Studio's existing tools with your Kotlin code, including autocomplete, lint checking, refactoring, debugging, and more.
Syntax is one of Kotlin's strongest advantages. Kotlin requires significantly fewer lines of code compared to what would be required in Java. This makes the code more readable and simpler, which generally also leads to the code being of better quality because bugs and errors are easier to find.
Android apps that contain Kotlin code are 20% less likely to crash. Interoperable: Call Java-based code from Kotlin, or call Kotlin from Java-based code. Kotlin is 100% interoperable with the Java programming language, so you can have as little or as much of Kotlin in your project as you want.
