-- 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.
