With this, we have covered the 14 famous apps that switched from Java to Kotlin and the perks they received. So, let’s move towards exploring what Kotlin means for a startup/established brands like yours.
In short, what are the benefits of choosing Kotlin for Android app development.
8 Advantages of Consider Kotlin for Android App Development
The very first advantage of using Kotlin for designing Android app is that it empowers you to write comparatively less lines of codes for accessing any functionality in the application. This eventually enhances the readability and quality of your Android codes.
Mature Development Environment
Kotlin, introduced back in 2011, has undergone various Alpha and Beta stages before officially launched in the market. Besides, every recently released language is compatible with its predecessors. This proves it to be a mature language for developing Android mobile apps.
Compatibility with Java
Another key feature why businesses and developers favor Kotlin for Android application development is its 100% interoperability with Java. That implies, you can use Java code into your Kotlin app development environment anytime, instead of rewriting the same codes in the latter.
Enhanced User Experience
Kotlin, being a mature development language, helps to create an app that crashes less, deliver better productivity, goes smoothly with the advanced technologies and tools, and more. This, in the long run, helps businesses and mobile app development companies in providing an enhanced user experience to their audience.
Faster and Secured Development
Since Kotlin avails clear and concise codebase, it reduces the chances of errors and crashes in the development process, which eventually makes Kotlin win over Java in terms of security – something that remained a barrier for Android in iPhone vs Android war to be startups’ first choice.
Exceptional Tool Support
As shared earlier, Kotlin comes with support for a complete set of tools including Android Studio, which leaves developers with no reason to overlook this language.
Backed by Google
Another benefit of considering Kotlin for reaping higher benefits in Android world is that it supported by Google. The tech giant has not only announced Kotlin as an official Android app development language, but is continuously making updates around the use of Kotlin.
Availability of Fail-Fast Compiler
Last but not least, Kotlin’s compiler works with fail-fast approach which highlights issues in coding itself that might result in app failure. It reports an issue and prevent developers from going further without resolving the issue.
This, in the long run, helps Kotlin app developers in reducing errors in their codes and thus, gain higher momentum in the market.
So, these were some of the benefits of choosing Kotlin over Java, which undoubtedly encourages everyone to start their Android journey with the former language.
But, is Kotlin really better than Java? Will it completely overtake Java?
Though it showcases various plus points over Java, the future of Kotlin is still not a threat to the latter. And a prime reason behind this is that Kotlin itself has various shortcomings, such as:-
Varied Compilation Speed
One of the prevalent limitations of Kotlin is that it does not offer faster compilation speed all the time. While it is faster than Java in some cases, it can be significant slow in other cases.
Still not Java
Though Kotlin is 100% interoperable with Java, the two are not alike. They are different at the core level, which makes it difficult for an Android app development company to easily migrate an Android app from Java to Kotlin, and vice-versa.
Limited Kotlin Experts
Above all, there are still higher number of developers embracing Java as compared to Kotlin app developers. This is again a challenge for someone who wish to get their Android mobile app designed with Kotlin.
Now, while these pros and cons of Kotlin will act as a weapon in planning Java to Kotlin migration, there are various other things to consider while switching profitably. So, let’s wrap up this article considering those factors that one should pay attention to while planning to join the bandwagon of these apps switched from Java to Kotlin.
Is Your Existing App’s Architecture Not Perfect?
When planning to be one of the aforementioned 14 apps that switched from Java to Kotlin, the very first thing you need to check is the type of architecture your app has. This implies, looking into if the existing mobile app architecture is loosely packed or well-maintained.
An idea of this helps to determine how much your app would suffer if some class or function gets deleted, overruled, or created while migrating from Java to Kotlin.
What You Expect from Kotlin App Development?
Another thing to consider while taking a step is to look into why migrating from Java to Kotlin is beneficial to your business and how. That implies, determining what benefits you will get when picking Kotlin as your Android development language and at what scale – rather than just following the market trend.
Does Your Team Has Comprehensive Knowledge of Switching App?
Moving from one development programming language to another brings a steep learning curve – something beyond simply referring to a Java to Kotlin guide. So, it is necessary to determine if your app development team is ready to welcome the changes and support you in this journey.
How to Hire the Right Android App Developers?
In case your team refuses or fail to assist you in this move, you need to hire a reputed Android app development. In other words, the last thing to consider while switching from Java to Kotlin is to look into factors to consider for hiring an app developer and the way interaction between you two occurs for reaping better outcomes.
Now, once you have ensured that all these pointers are in place, you can jump into the world of these apps that switched from Java to Kotlin for gaining the limelight in the market.
