Why Use Kotlin For Android Development

Android Apps

When it comes to Android development, there are several programming languages to choose from. Java has been the traditional choice for many years, but in recent times, a new language has gained significant popularity – Kotlin. As an Android developer who has worked extensively with both Java and Kotlin, I can confidently say that Kotlin offers several advantages over Java, making it the ideal choice for Android development.

Simplicity and Conciseness

Kotlin is known for its simplicity and conciseness, which makes it easier and faster to write code. With Kotlin, you can achieve the same functionality with fewer lines of code compared to Java. This not only improves productivity but also makes the codebase more readable and maintainable.

Null Safety

One of the biggest pain points in Android development is dealing with null pointer exceptions. Kotlin addresses this issue by providing built-in null safety features. With Kotlin, you can declare variables as nullable or non-nullable, reducing the chances of null pointer exceptions at runtime. This not only improves the stability of your app but also saves valuable debugging time.

Interoperability with Java

One of the great things about Kotlin is its seamless interoperability with Java. If you have an existing Android project written in Java, you can easily integrate Kotlin code into it without any issues. This means you can start using Kotlin gradually, adding new features or rewriting existing code, without the need to rewrite your entire project.

Functional Programming

Kotlin incorporates many functional programming concepts, such as higher-order functions, lambda expressions, and extension functions. These features enable you to write more expressive and concise code, improving the overall quality of your Android app. Functional programming also promotes immutability, which leads to fewer bugs and easier debugging.


Coroutines are a powerful feature introduced in Kotlin for handling asynchronous programming. They provide a simpler and more efficient way to write asynchronous code compared to traditional callbacks or reactive programming libraries. Coroutines make it easier to handle background tasks, network requests, and other asynchronous operations, resulting in cleaner and more maintainable code.

Community and Support

Kotlin has gained tremendous community support since its introduction by JetBrains. The Kotlin community is vibrant and growing, which means you have access to a wide range of resources, tutorials, and libraries to help you in your Android development journey. Additionally, major companies like Google have officially endorsed Kotlin, ensuring its longevity and continued support.


Kotlin has quickly become the preferred choice for many Android developers, including myself. Its simplicity, null safety, interoperability with Java, functional programming features, coroutines, and strong community support make it a powerful language for Android development. If you’re starting a new Android project or considering migrating from Java, I highly recommend giving Kotlin a try. Once you experience the benefits it offers, I’m confident you’ll be convinced, just like I was.
