A Step-by-Step Tutorial to Add Kotlin to Your Java Android Project

Discover a comprehensive tutorial about how to add Kotlin to your existing Java Android project. With the robust support of Kotlin in Android Studio, you can now include Kotlin files in your Java project and make the most of powerful tools such as debugging, code completion, refactoring, lint checking, and more.

How to Add Kotlin to Your Project?

To integrate Kotlin into your Java Android project, just follow these straightforward steps:

  • Open File > New, and choose an Android template.
  • Select Kotlin as the source language.
  • Complete the wizard and create your Kotlin file.

Alternatively, click File > New > File/Kotlin Class if you don’t encounter this option.

By doing so, Android Studio will show a warning message that Kotlin isn’t configured in your project. Therefore, click on “Configure” and choose to configure Kotlin for all modules that contain Kotlin files.

Organizing Kotlin Files and Converting Java Code to Kotlin

By default, Kotlin files are saved on the src/main/java/ folder. Yet, you can save them at the src/main/kotlin/ directory. If you want to convert your Java code to Kotlin, you have two easy alternatives. You can either copy your Java code into a new Kotlin file or convert the Java file to a Kotlin one by clicking on Code > Convert Java File to Kotlin File.

Frequently Asked Questions (FAQ)

1. Can I use my existing Java code with Kotlin?

Absolutely. Kotlin is interoperable with Java, which means you can use your Java code in Kotlin files.

2. What are the main benefits of using Kotlin in my Android project?

Kotlin is a modern, clear, and concise programming language that offers better performance, safety, and less boilerplate code than Java. Moreover, it provides a sleek integration with different libraries, making it easier to write efficient and maintainable code.

3. How do I know if my project is Kotlin-ready?

To check your project’s compatibility with Kotlin, select “Configure Kotlin in Project” from the “Tools” menu. This feature will scan your project for changes or updates and help you with the Kotlin conversion process.

4. Are there any cons to using Kotlin?

Not really. At first, Kotlin’s syntax may look unfamiliar to some developers, but its clear and reduced writing style usually makes coding faster, smoother, and more pleasant.
