Is Kotlin a suitable language for Android development

As Android app development continues to grow, developers are constantly looking for ways to improve their workflow and write more efficient code. One of the most popular languages for Android development is Kotlin, but is it really the best choice? In this article, we will explore whether Kotlin is a suitable language for Android development.

What is Kotlin?

Kotlin is a statically typed programming language that runs on the Java Virtual Machine (JVM). It was developed by JetBrains and is designed to be more concise and expressive than Java, while still maintaining compatibility with existing Java codebases. Kotlin has been officially supported by Android since API 21, and many developers prefer it over Java due to its improved readability and performance.

Why Use Kotlin for Android Development?

There are several reasons why Kotlin is a suitable language for Android development:

Improved Readability

One of the main benefits of Kotlin is its improved readability compared to Java. Kotlin code is more concise, and it uses less boilerplate code than Java. This makes it easier to read and understand, especially for developers who are new to the language or who have a background in other programming languages.

Better Performance

Kotlin code is generally faster and more efficient than Java code. Kotlin uses just-in-time (JIT) compilation, which allows it to optimize code at runtime and improve performance. Additionally, Kotlin’s strong typing system helps prevent common errors that can slow down Java apps.

Improved Interoperability with Java Libraries

Kotlin is fully interoperable with Java libraries, so developers can easily use existing Java codebases in their Kotlin projects. This makes it easy to leverage the vast library of Java tools and frameworks available for Android development.


Kotlin is a flexible language that can be used in a variety of contexts. It can be used for both backend and frontend development, and it has built-in support for functional programming paradigms like lambda expressions and higher-order functions.

Real-Life Examples of Kotlin in Action

There are many real-life examples of Kotlin being used in Android development. One example is the popular messaging app, Telegram. Telegram uses Kotlin extensively in its Android codebase, and it has reported significant performance improvements since switching to Kotlin. Another example is the banking app, Revolut. Revolut’s Android app was rewritten in Kotlin, and the team reported a 40% reduction in code size and a 30% improvement in app speed.

Expert Opinions

Many experts in the industry consider Kotlin to be a suitable language for Android development. Google has officially supported Kotlin since API 21, and many developers have reported positive experiences using the language. Additionally, Kotlin has been used successfully by large companies like Telegram and Revolut, which speaks to its effectiveness in real-world scenarios.

 Expert Opinions


In conclusion, Kotlin is a suitable language for Android development. It offers improved readability, better performance, and easier interoperability with Java libraries. Additionally, it is a flexible language that can be used in a variety of contexts. While there may be some debate about whether to use Kotlin over Java, the evidence suggests that Kotlin is a viable choice for Android developers.
