Why Prefer Kotlin for Android App Development?

As of 2023, Kotlin has become the preferred language for Android app development, with more than 60% of Android developers now using it over Java. Initially introduced by JetBrains in 2011 and later officially endorsed by Google in 2017, Kotlin offers several advantages that make it a top choice for Android application development.

This shift has significant implications for businesses and developers looking to create high-performance Android applications. Kotlin is more modern, concise, and expressive compared to Java, providing developers with a better experience and improved productivity. Whether you’re hiring an Android application development service or working with an Android app development company, Kotlin’s benefits are undeniable.

In this article, we will explore why Kotlin has become a favorite for Android app developers and why it is the ideal language for your next Android project.

1. Concise and Readable Code

One of the primary reasons Kotlin is preferred over Java is its ability to produce concise code. Kotlin’s syntax is simpler and less verbose than Java, leading to fewer lines of code and easier maintenance. This helps developers write faster, more efficient code while improving overall readability.

Key Benefits of Concise Code:

  • Reduces Boilerplate Code: Kotlin eliminates the need for repetitive code, which is common in Java.
  • Improved Code Quality: With fewer lines of code, the chances of bugs or errors are reduced.
  • Faster Development: Developers can focus more on app features rather than writing repetitive boilerplate code.

Example:
In Java, setting a listener requires multiple lines of code, whereas Kotlin can do this in just one line:

button.setOnClickListener { 

    // handle click 

}

In comparison, the equivalent Java code takes several lines, making Kotlin much more concise and efficient.

2. Interoperability with Java

Kotlin is fully interoperable with Java, which means you can use Kotlin and Java together in the same project. This is especially beneficial for companies that already have an existing Android codebase written in Java and want to gradually transition to Kotlin without needing to rewrite the entire codebase.

Key Considerations:

  • Incremental Migration: You can convert your Java code to Kotlin bit by bit.
  • Reuse Existing Libraries: Kotlin allows seamless integration with Java libraries and frameworks.
  • Compatibility: Kotlin code can call Java code and vice versa without issues, allowing for a smooth integration.

Example:
If your app uses an existing Java library, you can use it in Kotlin with minimal changes to the code. This helps developers incorporate Kotlin without disrupting the overall project structure.

3. Null Safety

One of Kotlin’s standout features is its null safety. Null pointer exceptions (NPEs) are a common source of crashes in Android applications, but Kotlin eliminates this problem with built-in null safety. In Kotlin, variables are non-null by default, and you have to explicitly mark variables as nullable if needed.

Benefits of Null Safety:

  • Prevents Runtime Errors: Kotlin ensures that null pointer exceptions are caught during compile time, not at runtime.
  • Cleaner Code: Developers don’t need to add unnecessary checks for null values manually.
  • Enhanced Stability: The app is less prone to crashes caused by null dereferencing.

Example:
In Kotlin, you can define a nullable variable like this:

val name: String? = null

And access it safely using the ?. operator:

val length = name?.length

This ensures that if name is null, it won’t cause a crash, unlike in Java.

4. Better Performance

Kotlin is designed to be fast and efficient. The language offers a performance level comparable to Java, thanks to its optimization for JVM (Java Virtual Machine) bytecode. Kotlin also allows developers to write inline functions and use lazy loading techniques, which further improve app performance.

Performance Improvements with Kotlin:

  • Faster Compilation: Kotlin’s compiler is optimized for performance, which leads to faster build times.
  • Reduced Memory Usage: Kotlin’s smart handling of objects and data structures helps to reduce memory overhead.
  • Native Code Support: Kotlin also supports Kotlin/Native, which can compile to native machine code, making it suitable for multi-platform projects.

Example:
Kotlin’s support for coroutines allows developers to write asynchronous code in a more intuitive manner, improving performance while handling background tasks.

GlobalScope.launch {

    // perform asynchronous task

}

This approach is more efficient than traditional threading and reduces the complexity of concurrent programming.

5. Modern Features

Kotlin comes with a suite of modern features that enhance developer productivity and app quality. These features are not available in Java, making Kotlin an attractive option for new Android app projects.

Modern Features in Kotlin:

  • Extension Functions: Kotlin allows you to extend existing classes with new functionality without modifying their source code.
  • Lambdas and Higher-Order Functions: Kotlin supports functional programming constructs like lambdas, allowing for cleaner, more expressive code.
  • Coroutines: Kotlin’s support for coroutines makes it easier to handle asynchronous programming, which is vital for Android apps.
  • Data Classes: Kotlin offers a built-in way to create classes that are mainly used to hold data, without writing getters, setters, or toString methods manually.

Example:
Using extension functions, you can extend the Android View class to set a click listener in a more readable way:

fun View.onClick(listener: (View) -> Unit) {

    setOnClickListener(listener)

}

6. Google’s Official Support

Since Google officially announced Kotlin as the preferred language for Android development in 2017, the language has received continuous support and updates, making it a reliable and stable choice for developers. Google has integrated Kotlin into Android Studio, and all new Android development guidelines encourage the use of Kotlin.

Benefits of Official Support:

  • Long-term Stability: Google’s support ensures that Kotlin will continue to evolve with new Android versions.
  • Tools and Libraries: Kotlin developers have access to official Android libraries and tools tailored for Kotlin.
  • Community Support: Kotlin enjoys an active and growing community of developers, ensuring that help is readily available.

7. Improved Developer Productivity

Kotlin’s simplicity and modern features result in higher developer productivity. The language allows developers to write less code, avoid repetitive tasks, and take advantage of higher-level abstractions. Additionally, Kotlin’s extensive tooling support, like auto-completion, code refactoring, and debugging tools, speeds up development.

Productivity Benefits:

  • Less Debugging: With fewer lines of code and more powerful type checking, Kotlin reduces the time spent on debugging.
  • Faster Iterations: Kotlin’s concise syntax allows faster iteration during the development process.
  • Better Documentation: Kotlin’s features, such as data classes and extension functions, lead to cleaner, better-documented code.

8. Growing Popularity and Community Support

Kotlin’s adoption by Android developers has been rapidly increasing, and its active community ensures continuous growth. As more developers adopt Kotlin, more tutorials, plugins, and resources become available, creating a richer ecosystem.

Community and Ecosystem:

  • JetBrains (the creators of Kotlin) and Google actively maintain the language.
  • Kotlin has comprehensive documentation, making it easier to learn and adopt.
  • KotlinConf is an annual event that brings together Kotlin enthusiasts, further boosting its popularity.

Conclusion

Kotlin offers many advantages over Java for Android application development. From concise and readable code to modern features and official support from Google, Kotlin is a language that enables developers to create high-quality, efficient, and stable Android applications. Its seamless integration with Java, improved performance, and growing community make it the best choice for new Android development projects.

Whether you are a startup looking to build a cutting-edge mobile app or an established enterprise in need of a reliable Android app development partner, Kotlin is the way to go. For businesses seeking Android Application Development Services, working with an Android app development company that specializes in Kotlin ensures that your app will benefit from the latest features and the highest quality standards.
