Can you post the full error message from the logs?

 

[fifiddu70]

excuse me, where can I find the log?

 

[stefanoa]

you can try:

Sub camera1_Ready (Success As Boolean)

    If Success = Null then Success = False    '<<< Add this line

    If Success  Then
    camera1.StartPreview
    Else
        ToastMessageShow("Cannot open camera.", True)
    End If
End Sub

** Activity (main) Resume **


** Activity (main) Pause, UserClosed = false **


Reposting event: camera1_ready

Yes. It happens inside ACL library. You can try to use the new CameraEx class.
