B4A and B4I Only

with this Class you can create a Device UID.

Creation Android:
  • App ID 'a fixed id on class global (Obfuscated) ' Example: 7038c50061d2e5db54e3bea7faf6a65ffaacd831
  • Phone Number on Simcard '"null"` if not provided by sim card (not all do this)
  • Hardware Serial 'android.os.Build.SERIAL
  • Device ID 'TelephonyManager.getDeviceId())
  • Subscriber ID 'TelephonyManager.getSubscriberId()` or `"null"
  • Sim Serial Number 'TelephonyManager.getSimSerialNumber()` or `"null"
with this information, the class create a SHA256 Hash.

Creation IOS:
  • App ID 'a fixed id on class global
  • Vendor Identifier
with this information, the class create a SHA256 Hash.

On IOS after uninstalling the App the Vendor ID is a other id, it is require to put the string in the keychain with:
B4X:
pp.KeyChainPut("uid",ac.GetDeviceUID)
and get:
B4X:
pp.KeyChainGet("uid")

THanks for sharing. For B4J maybe some ID of motherboard and the processor ID can be got ?

Seems, there is come codes for Windows OS
