Android studio sync settings between different computers

You can do this by configuring the Settings Repository available under the menu File > Settings Repository.

As per the official documentation the settings repository can be either a Github or Bitbucket repository. Though the documentation is for Intellij Idea but the functionality is available in Android Studio as well.

For syncing up your settings via repository, follow the official instructions.

The way I do it is exporting settings from Android Studio into Jar archive.

This Jar can then be imported in another instance of Android Studio, or, even, another instance of IntelliJ platform (which is very convenient if you also work with PyCharm etc.).

Take a look at IntelliJ's official documentation: Exporting and Importing Settings
