I've successfully established fingerprint authentication in my app. However, when i add new fingerprint in my android settings, the fingerprint sensor does not respond in my app (scanner still works correctly for unlocking my phone). Am i missing something important there?
Yes, you missing something verry important. It's a security case. There is no possibility to read fingerprint secured data after you add new fingerprit, so everything works as it should.
I hope I was helpfull :)
