incendio Well-Known Member Licensed User Longtime User Jun 27, 2018 #1 Hello, I tried fingerprint library from https://www.b4x.com/android/forum/threads/fingerprint-authentication.72500/ with real device on Oreo 8.0. Changed a code for sub Auth_Complete to be like this Code: Sub Auth_Complete (Success As Boolean, ErrorMessage As String) If Success Then ToastMessageShow("You have been authenticated!!!", True) Else fingerprint.Cancel ToastMessageShow($"Error: ${ErrorMessage}"$, True) Log(ErrorMessage) End If End Sub If scan succeded, the app worked OK, message "You have been authenticated!!!" appeared, but if scan failed, fingerprint cancel and the error message never called. Any idea why it didn't work as expected?

incendio Well-Known Member Licensed User Longtime User Jun 28, 2018 #6 I changed Sub Auth_Complete in FingerPrintManager.bas to like this Code: Private Sub Auth_Complete (Success As Boolean, ErrorCode As Int, ErrorMessage As String) ToastMessageShow("Fingerprint Completed.", True) If ErrorCode = 5 Then Return 'cancel CallSub3(mTarget, mEventName & "_complete", Success, ErrorMessage) End Sub If FingerPrint scan successded, message "Fingerprint Completed." showed, but if FingerPrint scan failed, this message didn't show. I guest a failed scan is not considered as a complete event so this event is never triggered. Upvote 0

You must be able to read the logs. Connect with B4A-Bridge and run your app in debug mode. Or in release mode with #BridgeLogger: True. Upvote 0
