android studio change package name
In Android Studio, you can do this:
For example, if you want to change com.example.app to my.awesome.game, then:
In your Project pane, click on the little gear icon ( Gears icon )
Uncheck the Compact Empty Middle Packages option
Compact Empty Middle Packages
Your package directory will now be broken up into 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
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
Enter image description here
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:
Refactor Directories
You may need to change the package= attribute in your manifest.
Clean and Rebuild.
Clean and Rebuild
Done! Anyway, Android Studio needs to make this process a little simpler.
