To change the app name, modify the "app_name" string resource in the string.xml file. This change will apply to the production variant. If necessary, you can adjust the "app_name" string resource in the string.xml (dev) file for the development variant. This way, "app_name" serves as the production release name, while the dev variant allows for testing purposes. Finally, rebuild and run your app to see the updated app name in action.
