If we place the variable outside this closure, this variable won’t be available before the project is built, and the build will fail.Īfter adding the Kotlin Gradle plugin, the next step is to apply the plugin. This is because, the buildscript is the entry point into this file when the project is being built. We placed this variable in the buildscript closure.You can check out this post about externalizing your dependencies versions using gradle extra properties for more info. The reason we have this is we may have other places in the project where we need to reference the Kotlin version, so it makes sense to “externalize” that value. We created a variable ext.kotlin_version.The project adle file looks like this:īuildscript Add the plugin to the dependencies closure in the project adle file. To configure the plugin, we first need to add the plugin to the root project’s adle, same way it’s done for the Gradle plugin (automatically). There is an automated tool to do this but sometimes, the tool messes things up, so let’s just walk through the manual process of applying the plugin in our adle files (both at the project level and the app-module level). Next step is to apply the Kotlin plugin to the project. Select the “Create Empty Activity” option at the end.įor more information on creating an Android project, check out this guide. Navigate to File > New > New Project and follow through project creation wizard. Now that we have the plugin installed, let’s go ahead and create a new Android project - the usual way we would. Just in case you’re using IntelliJ IDEA 15 or above, you’re in luck - Koltin plugin ships with the IDE. When the install is complete, you will need to restart Android Studio to apply the new plugin. To do this, navigate to Preferences > Plugins > Browse Repositories and search for “Kotlin” then, click on “Install” as shown in the figure below. First, we’re going to go ahead and install the plugin. The good people at JetBrains have created an IntelliJ/Android Studio Plugin for Kotlin. Let’s get started! Install Kotlin Plugin for Android Studio In this post however, we will learn how to set up Android Studio for Kotlin development and will write our “Hello World” app in Kotlin. There are tons of articles that talk about the advantages of Kotlin in comparison to Java, so I won’t be covering that in this post. Kotlin is statically typed, it runs on the JVM and offers a lot of benefits. Kotlin is a new programming language developed by JetBrains - the makers of IntelliJ IDE which the Android Studio is based on. If you have been following the latest trends in the AndroidDev world, you are likely to have heard about Kotlin.
