Android Question Error when executing Back key on empty Edittext

[RoseAsano]

Sorry for my English. I write from Brazil.

I'm having a problem I can't solve. When I press the Back key on an empty EditText,
the error below occurs. I tracked it, and the last event executed before the error is the routine below.
The returned KeyCode is 67, so Activity.Finish is not executed.

Sub Activity_KeyPress (KeyCode As Int)

If KeyCode = KeyCodes.KEYCODE_BACK Then
Activity.Finish
end If
End Sub


Log:

Why are you wasting your time with activities??? Switch to B4XPages.

The signature of this event is:

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event

It's a legacy system.
