Top Apps That Migrated From Java To Kotlin in 2024 And Why? Apps migrated from Java to Kotlin can effectively work on mixed-language projects.

We are currently witnessing the rise of the Kotlin programming language in the sector of mobile application development. 

It's been almost two years since Google announced Kotlin' as an official programming language for Androids apps and Android app development at it’s 2017 I/O Conference.  

And since then, a number of web, as well as mobile app developers, have made the decision to migrate their apps from Java to Kotlin. This is because the Android app developers no longer have to be solely dependent on the Java programming language as Kotlin is to enable to work easily on projects that are based on mixed languages. 

This further makes Kotlin highly compatible to be used with Java and Objective C. So, one can say that the learning curve of this new stellar language is much broader. Now let’s find the answers behind this need for Java to Kotlin migration. 

Why is Kotlin Better?

Although, we have previously written an entire detailed article on ‘Why Kotlin Is Preferred Language For Android Development’ that showcases the need behind this migration of java to Kotlin apps. It’s time to refresh our memory with the benefits that Kotlin offers to Android app mobile app development. 

Benefits of Kotlin 

  • Highly compatible with Java
  • Similar syntax to Java 
  • Backed up by Google 
  • Android Studio supports 
  • Modern & expressive language
  • Excellent tooling support 

Things You Need to Know About Kotlin

Now that we have gone through the main reasons why you need to consider to convert your Java app to a Kotlin app. But with the pros comes cons as well, that means there are some shortcomings related to Kotlin. Here are some of the other facts about the Kotlin programming language that you need to be aware of. 

Shortcomings of Kotlin
