Hello,

To change the package name of an Android project, you need to follow these steps:

1. Open your Android project in Android Studio.
2. In the Project view (usually located on the left side of the screen), navigate to the root of your project.
3. Right-click on the package name you want to change and select "Refactor" from the context menu.
4. From the Refactor menu, choose "Rename" (or "Rename Package" depending on your version of Android Studio).
5. In the Rename dialog, enter the new package name you want to use and click "Refactor".
6. Android Studio will prompt you to confirm the changes and show you a preview of the modifications that will be made.
7. Review the changes and make sure everything looks correct. Click "Do Refactor" to proceed.
8. Android Studio will update the package name throughout your project, including all the necessary file paths and references.
9. After the refactoring process is complete, you may need to update any references to the old package name manually.
10. For example, if you have hardcoded the package name somewhere in your code or configuration files.

It's important to note that changing the package name can have implications for your project, such as breaking

dependencies or causing issues with app signing. Make sure to test your app thoroughly after changing the

package name to ensure everything works as expected.

Additionally, changing the package name might require adjustments to your project's build files and configurations.

For instance, if you are using Gradle, you may need to update the applicationId in your build.gradle file.

Remember to back up your project before making any significant changes, just in case anything goes wrong during the process.

Thanks..
