Kotlin is becoming an increasingly popular language choice among Android developers. It is a great alternative to Java, offering improved readability, interoperability, and robustness. It provides developers the ability to utilize different approaches when it comes to coding. With the introduction of the Android Studio 3.0, Google has officially made Kotlin the preferred development language for Android. This tutorial will provide you with a step-by-step guide for developers to retrofit Android with Kotlin.
What is Kotlin?
Before diving into the retrofitting process, it is important to establish a firm foundation understanding of what Kotlin is and why it is being adopted by Android developers. Kotlin is a statically typed programming language designed with a modern and back-end development in mind. It is one of the official statically typed programming languages on the Android platform, with the other primary option being Java. Kotlin allows for easier coding than Java due to its improved readability and functionality. It is highly interoperable with Java and C++, allowing developers to use components from either language and seamlessly integrate them into their Kotlin code.

Why Use Kotlin?
Kotlin has several advantages over Java that make it attractive to developers. For starters, it is more concise, resulting in less code for developers to write and debug. Additionally, since Kotlin is highly interoperable with both Java and C++, developers can utilize components from all three languages and not have to rewrite existing code. Additionally, the language is highly robust, meaning it provides greater protection from errors or vulnerabilities in the code.
Kotlin’s popularity has grown significantly in recent years, to the point where Google has made it an official language for Android development. This commitment from Google has been further bolstered by the introduction of Android Studio 3.0, which includes several tools specifically designed for Kotlin development. With the increased support from Google, Kotlin is quickly becoming the go-to language for Android developers.
Getting Started With Kotlin
As mentioned previously, Android Studio 3.0 is the go-to development environment for Kotlin. This version of Android Studio includes a number of features specifically designed for Kotlin, such as an asynchronous programming model, improved debugging tools, and support for Lambdas and higher order functions. Additionally, this version includes features like the Kotlin Playground and the Refactoring tool, which make it easier for developers to write and debug code.
In order to get started with Kotlin, the first step is to download and install Android Studio 3.0. Once installed, developers can create a new project using Kotlin by selecting the “Create New Kotlin Project” option. This will generate the necessary files and configurations needed to start writing and running code using Kotlin.

Retrofitting the App With Kotlin
Once the development environment is configured and the project is created, the next step is to begin the process of retrofitting the app with Kotlin. Retrofitting is the process of converting an existing app, written in Java, to Kotlin. The retrofitting process can be divided into three main steps:
- Code Conversion: The first step is to convert the existing Java code into the Kotlin syntax. This can be done manually or automatically through the use of tools such as the Kotlin Conversion tool.
- Image Conversion: The next step is to convert the existing images into Kotlin code. This is accomplished by using the Image Conversion tool, which converts the images into a single Kotlin drawable file.
- Testing: The final step is to test the newly converted code to ensure that it works as intended. This helps to identify any remaining bugs in the code and allows developers to quickly fix them.
Once the retrofitting process is complete, the final step is to publish the new Kotlin-based app. Doing so will enable developers to benefit from all of the advantages that Kotlin offers.
Conclusion
Kotlin is becoming a popular language choice among Android developers for its improved readability, robustness, and interoperability. Additionally, its popularity has been further bolstered by the introduction of Android Studio 3.0. With this version of the development environment, developers have the ability to easily transition their existing apps from Java to Kotlin. This tutorial provided a step-by-step guide for developers to retrofit Android with Kotlin, from creating the development environment to publishing the finished product.
