Rename package in Android Studio

Solution 1:

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 the Compact Empty Middle Packages option

   

3. Your package directory will now be broken up into 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.

Solution 2:

Another good method is: First create a new package with the desired name by right clicking on the Java folder → New → Package.

Then, select and drag all your classes to the new package. Android Studio will refactor the package name everywhere.

Finally, delete the old package.

Done.

Very important:

You have to manually change AndroidManifest.xml and build.gradle file to the new package if you use this method.
