Android Studio Plugin Development
Android Studio plugins extend or add functionality to the Android Studio IDE. Plugins can be written in Kotlin or Java, or a mix of both, and are created using IntelliJ IDEA and the IntelliJ Platform. It's also helpful to be familiar with Java Swing. Once completed, plugins can be packaged and distributed at JetBrains Marketplace.
Android Studio plugins are not Android modules or apps to run in the Android operating system, such as smartphones or tablets.
Configuring IntelliJ Platform Projects for Android Studio Plugin Development
To create a new Android Studio plugin project, follow the tutorial on the Getting Started with Gradle page. The tutorial produces a skeleton project suitable to use as a starting point for an Android Studio plugin. On the New Project Configuration Screen of the New Project Wizard tutorial, choose Gradle from the product category pane as described in the tutorial, not Android. Some minor modifications to the skeleton project are needed, as discussed below.
Matching Versions of the IntelliJ Platform with the Android Studio Version
For API compatibility, it is essential to match the version of the IntelliJ Platform APIs used for plugin development with the target version of Android Studio. The version number of Android Studio contains the version of the underlying IntelliJ Platform APIs that were used to build it.
The actual Android Studio version doesn't entirely reflect the (YEAR.MAJOR.MINOR) version of the IntelliJ Platform. The Android Studio version presented below is
2021.1.1 Patch 1, but the
2021.1 part marked with the green rectangle refers to the IntelliJ IDEA release.
To find the version of the IntelliJ Platform used to build Android Studio, use the Android Studio About dialog screen. An example is shown below. In this case, the (BRANCH.BUILD.FIX) version of the IntelliJ Platform is
211.7628.21 – marked with the blue rectangle – is corresponding to the IntelliJ IDEA version
In your Gradle build script, you should set both versions – build number and the release number – to the
intellij.version property. To figure out the exact release number based on the build number, visit the IntelliJ Repository Releases listing and check the
The Gradle build script configuration steps section below explains how to set the IntelliJ Platform version to match the target version of Android Studio.

Configuring the Plugin Gradle Build Script
The use-case of developing for a non-IntelliJ IDEA IDE is reviewed in the Plugins Targeting Alternate IntelliJ Platform-Based IDEs section of the Configuring Gradle for IntelliJ Platform Plugins page. The particular example in that section discusses configuring a plugin project for PhpStorm, so the details for an Android Studio plugin project are reviewed here.
Here are the steps to configure the Gradle build script for developing a plugin to target Android Studio:
The Gradle plugin attributes describing the configuration of the IntelliJ Platform used to build the plugin project must be explicitly set. Continuing with the example above, set the
191.8026.42. Alternatively, specify
intellij.localPathto refer to a local installation of Android Studio.
Android Studio plugin projects that use APIs from the
androidplugin must declare a dependency on that plugin. Declare the dependency in the Gradle build script using the
intellij.pluginsattribute, which in this case lists the directory name of the plugin.
The best practice is to use the target version of Android Studio as the IDE Development Instance. Set the Development Instance to the (user-specific) absolute path to the target Android Studio application.
The snippet below is an example of configuring the Setup and Running DSLs in a Gradle build script specific to developing a plugin targeted at Android Studio.
Configuring the Plugin plugin.xml File
When using APIs from the
android plugin, declare a dependency:
As discussed in the Plugin Dependencies section of this guide, a plugin's dependency on Modules Specific to Functionality must be declared in plugin.xml. When using Android Studio-specific features (APIs), a dependency on
com.intellij.modules.androidstudio must be declared as shown in the code snippet below. Otherwise, if only general IntelliJ Platform features (APIs) are used, then a dependency on
com.intellij.modules.platform must be declared as discussed in Plugin Compatibility with IntelliJ Platform Products.
