Is Kotlin Official Language For Android

Android Apps

As a developer who has been working with Android for several years, I have witnessed the rise of Kotlin as a powerful programming language. In this article, I will explore whether Kotlin is the official language for Android development and share my personal experiences and thoughts on the matter.

Introduction to Kotlin

Kotlin is a modern programming language that runs on the Java Virtual Machine (JVM). It was developed by JetBrains, the company behind popular IDEs like IntelliJ IDEA. Kotlin was designed to be concise, expressive, and safe. It has gained popularity among developers due to its seamless interoperability with Java and its ability to eliminate many of the pain points of Java development.

Is Kotlin the Official Language for Android?

In May 2017, at the Google I/O conference, the Android team announced official support for Kotlin as a first-class language for Android development. This was a significant milestone for the language, as it meant that Kotlin would receive the same level of support and resources as Java for Android development. Since then, Google has actively promoted and integrated Kotlin into its ecosystem, further solidifying its position as the preferred language for Android development.

Benefits of Using Kotlin for Android Development

One of the main advantages of using Kotlin for Android development is its improved syntax, which allows developers to write more concise and readable code. Kotlin also provides a number of powerful features that enhance developer productivity, such as null safety, extension functions, lambdas, and coroutines. These features not only make the code more expressive but also help to prevent common programming errors and reduce the amount of boilerplate code required.

Another benefit of Kotlin is its seamless interoperability with existing Java codebases. This means that developers can gradually migrate their apps from Java to Kotlin without having to rewrite the entire codebase. Kotlin can call Java code directly, and vice versa, making it easy to transition between the two languages. This flexibility is particularly valuable for teams that have already invested a significant amount of time and effort into Java development.

My Personal Experience with Kotlin for Android Development

As someone who has been using Kotlin for Android development for several projects, I can confidently say that it has greatly improved my productivity and the quality of my code. The concise syntax and powerful features of Kotlin have allowed me to write cleaner and more maintainable code, which has reduced the number of bugs and made my apps easier to maintain.

Furthermore, the seamless interoperability with Java has allowed me to integrate existing Java libraries and frameworks into my Kotlin projects without any issues. This has saved me valuable time and effort, as I didn’t have to rewrite or replace existing code that was already working perfectly fine in Java.


In conclusion, Kotlin is indeed the official language for Android development. Its official support from Google and its numerous benefits make it a compelling choice for developers who want to build Android apps. The language’s improved syntax, powerful features, and seamless interoperability with Java have all contributed to its popularity and adoption among the Android development community. As a developer who has embraced Kotlin, I highly recommend giving it a try and experiencing its advantages firsthand.
