Read the MAC address
Exists a way to read the MAC address of the Phone or other unique number?
Thanks for help
GUI-O application cannot read MAC addresses due to Android security policy.
There is no guarantee for a unique number that will persist even after factory reset. There is a ANDROID ID that persists through uninstall / install but can also change under some circumstances (such as developer using a new app signing key).
GUI-O currently cannot return ANDROID ID value, but it is possible to implement.
Can I ask why are you trying to achieve?
