To add an icon of your Android application to the top of the device, where the user can switch Wi-Fi, Bluetooth, other settings, you'll want to use the SystemOptions class to achieve this. You can utilize the SystemOptions class to set the icon and functionality for your application in the System Control Panel.

Here's an example of how you might achieve this using the SystemOptions class:

SystemOptions().edit().putString("sysctlowershow", "your_icon_identifier").apply();
SystemOptions.getSharedPreferences().edit().put("sysctlowericon", "your_desired_functionality").apply();

Replace "your_icon_identifier" with the identifier of your application's icon, and "your_desired_functionality" with the functionality you want to associate with your icon.

By implementing the above code, you can add your application's icon to the System Control Panel at the top of the device, providing users with convenient access to your app's functionality other system settings.
