Why Kotlin Is a Rising Star Among Android Developers

Kotlin has seen a dramatic rise in popularity over the past couple of years. Its adoption as an alternative to Java is particularly remarkable. Whether it’s native Android app development or cross-platform apps, Kotlin’s presence is everywhere. Google started to support the language officially in 2017. Since then, a staggering number of developers worldwide have switched to Kotlin. But what makes Kotlin so popular? Or is Kotlin overrated? Those are the questions this blog post will answer — elaborately.

The buzz around Kotlin significantly challenges the establishment of Java language — especially for Android app development. You could draw a comparison with Swift, for example. Apple launched Swift as a modern successor of Objective-C. Over the past few years, Swift has completely taken over the iOS niche, replacing Objective-C. It could well be the case for Java and Kotlin over the coming years. So, without any further ado, let’s take a closer look at what makes Kotlin better than Java.

Advantages of Using Kotlin for Android Development

Kotlin is a modern programming language with an array of unique features. Be it the seamless development experience or unique server-side capabilities, developers love Kotlin for many reasons. Below are some of the most striking features of Kotlin.

Immutability

Immutability is one of the most talked-about features of Kotlin. In Kotlin, mutable is represented by the keyword ‘Var’ and immutable by the keyword ‘Val.’ Once an immutable reference is assigned, you cannot assign it to anything else. Also, immutable values of the reference cannot be mutated. While writing code in Kotlin, you can choose between an immutable collection, including maps and sets. However, the language also enables you to go for mutable implementations.

Less Code

With Kotlin, you need to write less code than Java and can yet develop a better app. The language has data classes that data hold only data, reducing the volume of code. Besides, you can also use Kotlin extensions to write less code. The extensions enable you to use functions to classes without modifying the source code. If you are planning to build an app for your business, hire a Kotlin app development company that can efficiently use these capabilities.

Null Safety

If you write code in Java, you must be familiar with Null Point Exception. In case you cannot recall, it pops up when you forget to check whether a variable was null. But with Kotlin, you don’t have to deal with this situation anymore. Kotlin solves this problem by making all the types non-nullable by default.

Interoperability

Kotlin is interoperable with Java. In other words, it’s 100% compatible with Java code. Interoperability makes Kotlin particularly attractive among Android developers. Since a large number of developers use Java before moving to Kotlin, this feature makes the transition smoother. Besides, you could choose to use both the coding languages selectively, per project-specific requirements.

Server-Side Coding Experience

Frictionless server-side experience is one of the most convincing selling points of Kotlin. The language offers an incredibly modern development experience with JVM technology. With Kotlin, you can use an array of cutting-edge web development frameworks. For instance, the Spring web framework, when combined with Kotlin, creates an efficient system for Android app development.

Kotlin also offers IDE support for Java developers. If you hire Android developers for your project, it’s wiser to look for both Java and Kotlin skills. Kotlin’s interoperability lets your development team seamlessly use both the frameworks for an optimal outcome.

Rounding off

When it comes to Android apps, Kotlin offers noticeably better native app development capabilities than Java. Kotlin Native could well be the single largest factor pushing you towards Kotlin. You can seamlessly run your Kotlin code across multiple platforms without using JVM. Kotlin is a modern language with unique features and functionalities.

Besides, you get access to all Kotlin library features regardless of the Android API level. And these are some of the most striking reasons Kotlin is increasingly becoming popular among developers of all experience levels. At Android Developer, an Android app development company, we are enthusiastic about the advanced capabilities of Kotlin. However, we use both Java and Kotlin per the specific needs of a project.

FAQs

FAQ

Q. Is Kotlin better than Java?

Kotlin adds many advanced features to mobile app development. It is being increasingly used by the Android app developers’ community. Kotlin can compile the code to JavaScript or native. It enables developers to build code that can run both on Android and iOS. It’s a statically typed language. Kotlin’s key features like built-in null safety support make apps flawless and user friendly.

Q. What is cross-platform mobile app development?

Cross-platform mobile development is the creation of apps that are compatible with multiple mobile operating systems, such as Android and iOS. Developers write the core of the application as an HTML5 or JavaScript mobile app and then make the necessary coding for different platforms.

Q. How much does it cost to build a Kotlin-based Android app?

The costs of developing a Kotlin-based Android app depend on several factors. Design complexity, development time, type of features, etc. play an important role in calculating the costs. We develop feature-rich Kotlin-based apps at a competitive price.
