When it comes to Android development, there is no doubt that Java holds a superior place on the programming language list and comes to mind first. Kotlin is a new programming language for Android, and it has been officially adopted as a statically typed programming language. In the future, Kotlin may be used to replace Java.

While it’s true that Android app developers should be thinking about whether they should learn Kotlin or Java, it’s also true that they should ask themselves, “Should I study Kotlin or Java?”

After creating an Android app, you must test it to ensure that it is free of errors. Repeat. the app provides this feature to assist you to test your Android app. That is a user interface test automation tool for Android apps that uses computer vision and machine learning and does not require coding knowledge.

Starting with Java is a good idea because there are many excellent resources that you won’t find in the Kotlin resources. Unfortunately, Java is also a bit difficult, because Kotlin is a JVM-based language. For Android developers, Kotlin is a language that can be used. Android developers can write apps in any language, however, the JVM is not used by Android.

Kotlin was a bit slow to catch on as an officially supported language for developing Android apps, despite Google’s full backing. Google I/O has reported that it has risen to the top of lists of “best languages to learn next” for statically typed programming languages. Is it, however, keeping up with Android’s fast-paced future development, or is it just another overhyped technology?

What’s wrong with Java and how to deal with Java issues in Android development:-

Java is prone to errors.

Verbosity and formality

The type system is in charge of null references.

There are no raw types.

In Kotlin, arrays are invariant.

Support for the IDE and tooling is excellent.

Kotlin is a programming language for businesses.

Without wildcards, use-site variance

There are no checked exceptions in Kotlin.

In this post, we’ll look at why Kotlin outperforms Java and how particular Kotlin features alleviate many of the problems that Java causes while developing Android apps. In this post, developers will learn about the advantages of switching to the understandable Kotlin language, which is more productive for developers and a better choice for you.

Let’s look at why Kotlin is such a popular and powerful language for Android app development. Should you think about making a change?

Why should you worry about Kotlin?

JetBrains, best known for its IntelliJ IDEA integrated development environment, introduced Kotlin, a general-purpose statically-typed programming language, in 2011. At the time, almost all programming was done in Java. Kotlin is a Java Virtual Machine (JVM) language. The Java Virtual Machine is where Kotlin is intended to be used. Android’s official coding language is Kotlin. The language is compiled into bytecode in Java 6/8, but it may also be compiled into JavaScript and react-native when other languages don’t.

Kotlin became an official statically-typed supported language for Android in 2017.

Why should you care about Kotlin and why should you use it for Android development?

Setup is simple

In general, Kotlin has numerous advantages for developers, including the ease with which you can convert your Java code to Kotlin and add the plugin to a new Android project. However, with Android Studio 3.0, getting started with Kotlin for Android development has never been easier. Simply tick and choose to build the activity under the ‘Include Kotlin Support’ box while configuring the new project, and then convert it to Android Studio using the automated converter tool.

Kotlin is completely compatible with Java

Kotlin is a Java-based programming language that is officially recognized as an Android support language. Kotlin is a completely “interoperable” language with Java. This makes Kotlin more accessible to you, and you can incorporate Kotlin code into your existing projects. The languages that generate similar bytecodes are Kotlin and Java. Simple pieces of your app can be written in Kotlin, which will operate with its structures and syntax. In my project, the Kotlin-Java mix code works great.

Reduces Boiler Plate Code and makes you happy

Kotlin is also far more readable, productive, and efficient, as it eliminates a lot of boilerplate code. It is currently the official language of Android development, and developers must write every day recommending that they learn Java. Kotlin can create all of that by itself and improve the speed of your app development lifecycle in less than 50 lines of code in Java.

Null References and Safety

Because Kotlin is so concerned about this, Android app developers believe that NullPointerExceptions are one of Kotlin’s most popular safety features. NullPointerException is a very basic way of representing the absence of a value and a chance to live another Exception. Null Safety in Kotlin is the most prevalent cause of crashes in Android apps nowadays, and it comes with a safe call operator. NullPointerExceptions (NPE) are readily avoided with Kotlin.

Conclusion

Kotlin is a programming language for businesses. Try it out for yourself.
Is it better to program in Kotlin or Java for Android? To begin with, Kotlin is a very new language compared to Java, and it is only just beginning to gain traction. Second, you should try out Kotlin, which includes support for Lambda expressions, and start reaping the benefits of writing less code than Java while also being easier to grasp and master.

Finally, Kotlin is a user-friendly language that may be used to create great Android applications. Kotlin can make your life easier as an Android developer. What you do for an Android application created in Java has remained the most popular language for development till now.

Thank you for taking the time to read this article. Of course, I’ll continue to write about Kotlin and Android in the future, so stay tuned! Questions and comments are always welcome.
