Renaming modules in Android Studio?

Android Studio >= 1.4.1

1. Right click the module -> Refactor -> Rename.
2. Enter the new name of the module, click OK.

Older versions of Android Studio

The following worked for me, tested in Android Studio (AS) 1.1 & 1.0.2, directly after importing a project.

Under the ‘Android’ tree view (ATV),

1. Right click the module name: app, Refactor -> Rename (to myApp, click ok)

2. Open settings.gradle

3. Change ':app' to ':myApp', and save

4. You will be prompted to ‘Sync Now‘, do it (the prompt is a blue link above the file)

   (Your project will disappear from ATV, but don’t worry, just exit AS)

5. From a file manager (outside of Android Studio), open your project root directory, and rename the folder app to myApp

6. Re-open your project in AS, and you will see your module and Gradle scripts re-appear under ATV! 🙂

Congratulations – your module has now been renamed! (whew, time for some tea)
