Hello,

To change the app name displayed on the device home screen and in the app launcher, you can 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 "res" directory.

3. Expand the "res" directory and locate the "values" folder.

4. Open the "strings.xml" file inside the "values" folder.

5. In the "strings.xml" file, you'll find a line of code that looks like this:

   xml

   <string name="app_name">Your App Name</string>

6. Modify the text within the <string> tag to your desired app name. For example:

   xml
   
   <string name="app_name">My New App Name</string>

7. Save the changes to the file.

8. Clean and rebuild your project to ensure the changes take effect. You can do this by selecting

   "Build" from the Android Studio menu and then choosing "Clean Project" followed by "Rebuild Project".

After rebuilding your project, the updated app name will be displayed on the device home screen and in the app launcher.

It's worth noting that the app name specified in the "strings.xml" file is typically used as the default app name.

However, some launchers or customizations may allow users to override the app name for display on the home screen.

Thanks..
