You'll use key Kotlin features to write your app code more quickly and concisely.
Learning to develop on Android is much more than learning APIs and shortcuts. It's training your brain to think like a mobile developer.
In this free course—developed by experts at Google—you will learn the fundamentals of building Android applications using Kotlin. The course covers architecture components, multi-screen navigation, data persistence, RESTful APIs and Material Design. By the end of the course, you’ll be able to create well-designed Android applications using Kotlin that can connect to the internet, store data and navigate between screens.
Kotlin is an open-source, modern programming language that lets developers use both object-oriented and functional programming techniques. It is concise, safe, and fully interoperable with Java. Kotlin is an official language for Android development and the community of Kotlin developers is growing rapidly, with major companies like Netflix, Pinterest, and Google using Kotlin.
