Transfer IntelliJ settings to to Android Studio
In order to transfer your existing settings from IntelliJ to Android Studio (or vice versa) select File -> Manage IDE Settings -> Export Settings... and select an appropriate path. Then in the other IDE you wish to transfer the settings to, select File -> Manage IDE Settings -> Import Settings and locate the previously exported .jar settings file.
You need to export the settings from IntelliJ (by clicking File->Export Settings), and then import them to Android Studio (with File->Import Settings).
The trick is you also need to disable 'IDE settings sync' in IntelliJ, because if it is enabled, the Export Settings action is hidden in the File menu.
