10 Kotlin Features To Boost Android Development

To use Android KTX, developers just need to add required dependency in app’s construct.gradle file. In Java we use POJO – Model classes regularly to hold information, the place we declare class properties and its getter-setter methods. Developers can directly entry the property with none need of getter or setter methods. When we use data lessons it routinely overrides beneath strategies.

Complete small duties one after the other whereas gaining expertise with a professional development setting. Learn the fundamentals of object-oriented programming and error-handling strategies. Android cellular improvement has been Kotlin-first since Google I/O in 2019.

You also can use the updateUser perform to update the user data. In this example, we’ve created an Observer that observes the userLiveData property of the UserRepository. When the information changes, the updateUserProfile function is identified as to replace the consumer interface accordingly. Now that we understand the advantages of LiveData, let’s explore the way to set it up in a Kotlin-based Android software. LiveData helps keep information consistency by delivering updates solely when the info changes.

Kandy: The Model New Kotlin Plotting Library By Jetbrains

Many startups and Fortune 500 companies have already developed Android purposes utilizing Kotlin, see the listing on the Google website for Android builders. By the tip of this tutorial, you’ll have a strong understanding of Kotlin and be prepared to begin building Android applications utilizing this highly effective language. Syntax of Kotlin is so easy and clear, that builders even without prior experience with the language, can instantly perceive Kotlin code and start working on it. The developers of JetBrains whereas creating the Kotlin language focused on simplicity and ease of studying. Kotlin by removing the null reference from the app code, offers relief to the builders from all the time-consuming tasks of repairing NPE.

This full course explains the means to construct an entire Android app using best practices. You will discover methods to use Android Jetpack, Firebase, Room, MVVM, Navigation, LiveData, and Kotlin Coroutines. Here is how you https://www.globalcloudteam.com/ can take the primary steps in growing Kotlin server-side purposes.

Extension operate helps to reuse code and decreases code redundancy. The above code is used to set a textual content to the TextView issue, with the ID ‘textview’ added to the layout file, in Java coding. Currently, your app has one exercise that has a structure file referred to as activity_main.xml.

With a large following of Android builders, Kotlin is consistently being improved by programmer inputs across tasks. Yes, iOS apps are additionally equally essential, as it is the second most popular mobile platform worldwide. Android growth has made a significant contribution to the world of mobile development.


Firstly, we begin by paying attention to the pros and cons of Kotlin language. In spite of the clamor round this new Java different, many Android builders are still confused about making the choice, and shifting their leanings to Kotlin. Moreover, the official Google assist played a serious position in drawing the focus of the Android developer community in the direction of Kotlin language. Along with Extension operate KTX also provides Extension properties, but to make use of properties we’ve to provide explicitly getter. This characteristic additionally eliminates the need of including Null checks in code which make code more clean and straightforward to read.

Create real-world functions from scratch and build a developer portfolio by the tip of your research. Nikunj is a Founder & CEO of a supreme Web and Mobile App Development Company. Which is successfully delivering companies in the realm of UI/UX design, net improvement, mobile app development, and enterprise solution. He’s enthusiastic blogger and his writing curiosity consists of mobile and internet development applied sciences, startup concepts and techniques. On the off probability that you’re hoping to vary to any of the brand new programming languages, you presumably can lay your hands on languages like Kotlin. In this example, UserViewModel exposes the userData LiveData, which is backed by the userLiveData from the UserRepository.

The number of developers gravitating in the direction of it could have even compelled their hand. Kotlin is a programming language that was developed by Jet Brains for modern multi-platform applications. Kotlin is a statically typed programming language for the JVM(Java Virtual Machine), Android, and the browser which is now formally supported by Google For Android. It has many features like capabilities, operator overloading, and lambda expressions. Because Java and Kotlin are highly appropriate, we will use them together in the identical project. For the JVM, it compiles to Java byte-code and it’s utterly interoperable with Java.

Google gave major push to Kotlin by labeling it most popular language for Android app development at Google I/O 2019 conference. For them, we’re going to clarify a few of the key benefits that Kotlin presents for Android developers. Consequently, with the backing of huge guns in know-how kotlin application development, mobile builders are gradually embracing Kotlin warmly. This has been already a quantity of years, since Kotlin emerged as the most viable various to Java, for programmers to construct Android apps. Sealed courses in Kotlin are used to limit class hierarchies.


This means you can write Kotlin and Java in the same project, and they will work collectively. IntelliJ (JetBrains IDE for Java) even permits direct conversion of Java code to Kotlin. As we compose, the Kotlin cellular utility improvement neighborhood is proceeding to develop.

In this course, you will discover ways to build native apps by creating an app called SpaceNotes. Familiarize your self with Kotlin syntax by solving quick programming challenges. Learn every thing about classes, collections, properties, builders, and generic capabilities.

Converting your Java code to Kotlin Open MainActivity.java file in your application. The most handy one is to call Find Action and begin typing an action name. Instead, you’ll have the ability to call this feature via the Code Convert Java File to Kotlin File menu entry.

This makes it simpler to handle error eventualities gracefully in your app. As a new language, it’s safe and expressive though it has a couple of disadvantages. It is getting enhanced day-to-day, and we will conclude by saying that it’s evolving as a favourite language for an Android developer. Contains resources, similar to strings and colours, utilized in your app. As a result, the Kotlin group continues to develop and thrive, and in the future, we are ready to expect more Android apps to depend on Kotlin. Often generally recognized as a common supply for app crashing, NullPointerException (NPE) is a major cause for bad app performance.

Specifically useful if you wish to characterize a finite set of courses. Most widespread use case of sealed class is to handle API success and failure response, let’s perceive with an instance. Data lessons can be created by just preceding class name with information keyword. Properties of data courses can be outlined instantly in major constructors.

  • LiveData helps keep information consistency by delivering updates solely when the data adjustments.
  • Properties of information courses may be defined instantly in major constructors.
  • LiveData is lifecycle-aware, which suggests it routinely stops and begins observing knowledge based mostly on the lifecycle of the element it’s certain to.
  • Nikunj is a Founder & CEO of a supreme Web and Mobile App Development Company.

Today, in this article we are going to look into 10 features of Kotlin that may assist Developers to boost Android growth. A robust grip on these features can make a considerable distinction in your productivity, code high quality, and total development workflow. Android Jetpack is a collection of Android software elements which can help you construct great Android apps easily. This course reveals the way to use these parts to simplify the event process.

Coding With Kotlin

This may be significantly useful when working with real-time data sources like databases or network requests. LiveData is lifecycle-aware, which suggests it automatically stops and begins observing knowledge based mostly on the lifecycle of the element it’s sure to. This ensures that you don’t need to manually manage when to begin and stop observing information. This course is designed to provide you a holistic understanding of Kotlin and Android growth, with hands-on examples and real-world purposes.
