Introduction. My first Extension.
This extension obtains the unique AndroidID, without any permissions. Obtaining the IEMI number, or the users name can have significant privacy concerns. This extension obtains a unique value from the device, that can only be changed when the device is reset to factory defaults.
This is a great way to track individual devices, without knowing who they are, or asking for scary permissions. This helps for GDPR and other type compliance.
A use case is you want to make sure that a device does not delete your application to get circumvent various things. I use it with firebase so I can track all sorts of stats, without ever knowing who the user is, and therefore I am very privacy compliant.
Just call the GetDeviceID, and then apply the GotDeviceID(deviceid) to whatever variable you want.
