[FREE] UUID - generate /retrieve a unique id of your device

v1 is HERE

V2 is updated for target api 30, so i post v2 here this community.

why this extension

Since we are not able to get DeviceId, get Imei, get Meid, get SimSerialNumber, get SubscriberId and get Serial from Android 10 and higher devices,
the most practical way is to generate a random string and save it on sdcard, and retrieve the string back from the file when needed.

This is what this extension is doing.



permission needed

This extension will ask READ_EXTERNAL_STORAGE permission, if denied, it will return empty string.

known issue

1.defautltFileScope need to be set to legacy, other wise no permission granted.

They are all the blocks. The first generates the uuid and stores it to a designated file. The second returns the uuid to a label. That is it!
