There are two basic ways to add a plugin in Android Studio. First, you can download in two ways:
- Download a zip plugin from GitHub or the JetBrains site.
- Download directly from Android Studio settings
In both ways, you need to install from the same place. In Android Studio go to:
Preferences ...
Plugins
Click Install JetBrains plugin or Browser Repositories (whichever you prefer)
Search for the Plugin
Click Install
Restart Android Studio to activate the plugin
If you have downloaded a plugin from github or another site, just click Install plugin from disk in step 3 and follow the remaining steps.
