Rename Package in Android Studio

In Android Studio, you can do this:

For example, if you want to change com.example.app to my.awesome.game, then:

1. In your Project pane, click on the little gear icon (  )
2. Uncheck / De-select the Compact Empty Middle Packages option
3. Your package directory will now be broken up in individual directories
4. 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
• Click Do Refactor in the bottom
• 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

5. Now open your Gradle Build File (build.gradle – Usually app or mobile). Update the applicationId in the defaultConfig to your new Package Name and Sync Gradle, if it hasn’t already been updated automatically:
6. You may need to change the package= attribute in your manifest.
7. Clean and Rebuild.
8. Done! Anyway, Android Studio needs to make this process a little simpler.
