How to generate Class Diagram (UML) on Android Studio (IntelliJ Idea)

I found a free plugin that can generate class diagrams with android studio.
It’s called SimpleUML.

Update Android Studio 2.2+:
To install the plugin, follow steps in this answer: https://stackoverflow.com/a/36823007/1245894

Older version of Android Studio
On Mac: go to Android Studio -> Preferences -> Plugins

On Windows: go to Android Studio -> File -> Settings -> Plugins

Click on Browse repositories... and search for SimpleUMLCE
(CE means Community Edition, this is what android studio is based on).

Install it, restart, then you can do a right click on the folder containing the classes you want to visualize, and select Add to simpleUML Diagram.

That’s it; you have you fancy class diagram generated from your code!
