Kotlin named Breakout Project of the Year at OSCON

Stephanie Saad Cuthbertson announces support for Kotlin during the Developer Keynote at I/O 2017.

Today at OSCON (the O'Reilly Open Source Software Conference), Kotlin was awarded the Open Source Award for Breakout Project of the Year.

There is no doubt to us why Kotlin received this award: it’s a fast moving (but thoughtfully developed) programming language that lets you write better code, faster. It’s great to see Kotlin continue to receive the sort of recognition as Breakout Project of the Year, building on other awards like #1 fastest growing language on Github.

We’re big fans of Kotlin, and we’ve heard that you are too – feedback from you is in part why we announced support for the language over two years ago. This meant bundling the Kotlin plugin in Android Studio, along with promising to support Kotlin-built apps going forward.

But there was a long way to go for many teams at Google to provide a first class experience with Kotlin in the Android ecosystem, and to convince developers that Kotlin on Android is not just a fad, but is here to stay.

If you haven’t tried Kotlin yet, now is a great time to start! In fact, in the past two years, we’ve been adding a number of new features and upgrades to the Kotlin for Android experience, including:

• Android Jetpack APIs now have first class support for Kotlin Coroutines, transforming the way we do async operations on Android. This includes Room, LiveData, ViewModels, WorkManager and more coming in the future.
  
  
• Many Jetpack libraries have Kotlin extension libraries (KTX) to make using them even more fluent with Kotlin.
• The compilation toolchain has received many improvements for Kotlin, including compiler enhancements, incremental annotation processing with KAPT, and Kotlin-specific R8 optimizations.
• All of our documentation pages now contain Kotlin code snippets, so you can easily compare how our APIs work in both languages.
  

• Most of our flagship samples are also written in Kotlin (including IOSched, Plaid, Sunflower and many more), along with any new samples that we make in the future.
• We've added a language switcher to our API reference pages, so you can have a Kotlin view of the AndroidX library and the Android framework.

• We doubled down on providing guidance to developers and teams who want to switch to Kotlin on our developers.android.com/kotlin pages.
• Our Developer Relations engineers are posting real life examples and guides on integrating Kotlin in your apps on our Medium publication, such as the great intro to Coroutines on Android series and many more.
• If you prefer to learn Kotlin in person, you can join one of the many Kotlin/Everywhere events happening around the world. If you are an organizer in a local developer community, consider signing up to host your own event!
  This initiative is a cooperation between JetBrains and Google.
• For those of you who don't have access to in-person training, we added a new, free course on Udacity for Developing Android apps in Kotlin. Our Kotlin Bootcamp for Programmers course is still available as well!
• We have worked with many external partners to gather feedback and learn about their experiences with Kotlin, such as this case study with Square.
  
• And lastly, we've enabled Kotlin as a supported language for Android app teams at Google. We're already seeing adoption in apps such as Google Home, Google Drive, Android System UI, Nest, with many more to follow.

The road to fully supporting Kotlin on Android was not always easy, but it was truly rewarding seeing Kotlin adoption among professional Android developers rise from a handful of early adopters to around 50% since the original announcement!

We were confident when we announced earlier this year at Google I/O 2019 that Android is going increasingly Kotlin-first, opening up the possibility for APIs built specifically around Kotlin and for Kotlin users, starting with the new, declarative UI toolkit - Jetpack Compose (still in early development).

We want to congratulate JetBrains, our partners through the Kotlin Foundation and creators of Kotlin, on receiving the OSCON Open Source Award today. It shows how disruptive and transformative Kotlin has been, and not just for the Android developer community, but beyond.

We know one thing: on Android, Kotlin is here to stay.
