Hi,
using the example for the 'use of biometric function downloaded from this link ( https://www.b4x.com/android/forum/threads/biometricmanager-biometric-authentication.111256/#content ) the app I have a problem that I can not solve.
the app is regularly installed , but on startup it closes with no errors in the log.
Only with the command "adb trace" I saw the stack of error calls:
What can it be due to?
Thank you very much
Roberto
