KotlinConf 2018 - Android KTX: A Dash of Kotlin Makes All the Difference! by Dan Kim

3rd October 2018

When Kotlin hit the Android scene, one of the first things many of us did was wrap difficult-to-use Android Framework APIs with extension functions. That little sprinkle of Kotlin made all the difference, and life was great — we finally we had a way to make our least favorite calls more concise and easier to work with!

Android KTX builds on this same idea and makes them available to everyone. It's a new set of open source Kotlin extensions (maintained by Google) that sits on top of commonly used Framework methods, abstracting much of the complexity and boilerplate away. This vastly improves the conciseness and readability of your code, making it more idiomatic and enjoyable to work with.

In this talk we'll start with a brief intro to KTX — what it is, why it's so great, and what it means for us as Android developers. Next we'll take a tour of what extensions are currently available, highlighting some of my favorites. We'll compare the old, hard ways of doing things against the new, friendlier ways that KTX provides so you can clearly see how life with KTX is better!

By the end you’ll have a better idea of 1) how you can improve your Android code by using KTX in your daily work and 2) what well-designed extension methods look like so you can wrap/extend the Android framework for your own use (or to contribute back into KTX!)

He's always enjoyed Android development, but working with Kotlin over the last two years has rocketed that enthusiasm to a whole new level. The Android community has been instrumental to his work and career, and he's a big believer in paying that forward. Outside of work, he's an avid Dad 👴, donut aficionado 🍩, pizza lover 🍕, and emoji enthusiast 😉.
