Rename root module in android studio

How to rename root module in android studio? I have tried (right click the module then click refactor then click rename) but I got warning “can’t rename root module”

How to&Answers:

I just pressed ctrl+shift+F to search my current root module name,and found the name to be in the settings.gradle file as rootProject.name= ,I renamed it and synced the project, now the root module name is changed.


This is tested for a pure Java projects (without any C/C++ code):

  • close the project and make a copy of the folder containing it
  • rename the new copied folder to reflect new project name
  • delete all *.iml files
  • reopen the project: Android Studio will resync Gradle, rebuild iml files
  • review the modules.xml file to remove reference to old project name
  • new project renamed works exactly as previous one: you can run the app without completely reinstalling it (all previous app data/settings/cache will be preserved)


In your Project pane, click on the little gear icon ( setting icon at the right top)

Uncheck / De-select the Compact Empty Middle Packages option

Your package directory will now be broken up in individual directories
Individually select each directory you want to rename, and:

Right-click it

Select Refactor

Click on Rename

In the Pop-up dialog, click on Rename Package instead of Rename Directory

Enter the new name and hit Refactor

Allow a minute to let Android Studio update all changes

Note: When renaming com in Android Studio, it might give a warning. In such case, select Rename All


Close the project. (File > Close)

Rename the root folder of the project.

At the welcome screen “Open an existing Android Studio project” and provide the new path.
