Basic Reskin

To change the applicationId in an Android Studio project (the unique identifier for your app used on the Google Play Store), follow these steps:

Steps to Change the applicationId

1. Open Android Studio

   • Launch your Android Studio and open the project where you want to change the applicationId.

2. Navigate to the build.gradle (Module: app) File
   

   • In the left-hand Project pane, expand the Gradle Scripts section.
   • Find and open the file named build.gradle (Module: app).
     

3. Locate the applicationId
   

   • In the build.gradle (Module: app) file, locate the following block under the android section (ex. com.example.yourapp):
     

4. Change the applicationId

   • Modify the applicationId to your desired new identifier. For example:
   • Make sure the new applicationId is unique and follows the standard reverse domain name format (e.g., com.newname.appname).

5. Sync the Project

   • After changing the applicationId, click Sync Now in the top-right corner of Android Studio to sync your project with the new applicationId.

6. Rebuild the Project

   • Go to Build > Rebuild Project to ensure the project is rebuilt with the new applicationId.

Testing Your Changes

• After syncing and rebuilding, run the app on a physical device or emulator to verify that it runs correctly with the new applicationId.

Important Notes

• Changing the applicationId does not affect your package structure in the code. It only changes the unique identifier used for deployment and distribution.
• If you have already published your app on the Google Play Store, do not change the applicationId, as it will be recognized as a new app.
