Error: Only the original thread that created a view hierarchy can touch its views

Hi everyone,

Reposting from https://github.com/blockchain-certificates/wallet-android/issues/25

One of our users is receiving an error when attempting to add us as an issuer to his Blockcerts wallet (Android). After entering our issuer URL, entering his one-time code, and tapping “Add Issuer,” he gets:

“Only the original thread that created a view hierarchy can touch its views.”

He has tried multiple times, over multiple days, and gets this error each time. Other users have been able to add us as an issuer with no errors during this same time frame.

Does this error ring any bells for anyone?

Very weird. Sounds like it could be an android version / model bug going on. Haven’t seen that one myself. Do you have any device information?

He reports that he’s using Pixel 2, Android version 9.
