Who is this presentation for?

  • Anyone who works with Android applications
  • Java developers interested in Kotlin

Prerequisite knowledge

  • A working knowledge of Java
  • Familiarity with mobile development on Android (useful but not required)

What you'll learn

  • Learn how to code Android apps in Kotlin


Kotlin—an alternative language that runs on the Java Virtual Machine—emphasizes static typing, null safety, and modern language features such as lambdas and extension functions. Kotlin is particularly appealing in the Android world, which does not yet support all the features of Java 8.

Kenneth Kousen offers an overview of Kotlin, with a focus on using it for Android development. You’ll learn about Kotlin’s essential syntax, data classes, operator overloading, extension functions using the Anko library, generics, working with collections and functional operations, interacting with the Sqlite database, and more.

The tutorial uses the latest version of Android Studio, which provides excellent support for Kotlin and Android development. Solutions to all the exercises will be provided in a GitHub repository.
