        // Android:

        // On Android, accessing the MAC address directly is restricted on modern Android versions (API level 23 and above) due to privacy and security concerns.
        // Apps targeting Android 6.0 (API level 23) or higher cannot access the MAC address of the device using standard APIs.
        // If you're developing for modern Android, consider using alternative identifiers (e.g., instance IDs) instead of the MAC address, as recommended by Google.
        //
        // Chilkat will not return MAC addresses for Android, regardless of the API level.
        // Only IP addresses are returned for Android.
