Android Question Error in BiometricManager class

[Humberto]

The error occurs inside BiometricManager

I tested in
Moto G6 Plus android 9 with fingerprint and OK
LG with android 4.12 with fingerprint works
Moto G5Plus with android 8.1 with fingerprint and crash

'This is inside BiometricManager
Public Sub CanAuthenticate As String
    Dim v As Int = Manager.RunMethod("canAuthenticate", Null)
    Select v
        Case 1
            Return "UNAVAILABLE"
        Case 11
            Return "NONE_ENROLLED"
        Case 12
            Return "NO_HARDWARE"
        Case 0
            Return "SUCCESS"
        Case Else
            Return "UNKNOWN"
    End Select
End Sub

The error occurrs in this line " Dim v As Int = Manager.RunMethod("canAuthenticate", Null)"

Error occurred on line: 30 (BiometricManager)

I put a Try and Catch to bypass but I can not use the fingerprint

Does it work if you also add:

AddPermission(android.permission.USE_FINGERPRINT)

I´ll try.
This cellphone is not with me.
