Android Question Remove all outline view

[Emme Developer]

Hi to all, can anyone helps me with this simple sub? I don't have any idea why it doesn't work. I've a panel. Each 3 seconds i create a panel inside it, at bottom of previously panel. I wrote a small sub that delete all outline panels. But i don't understand why, it give me an error.

This is the sub that i use to remove panel:

Private Sub RemoveOutlineView
   
    Log(pnlTwView.NumberOfViews & " view")   
    For Each p As Panel In pnlTwView
        If (p.Top+p.Height) > pnlTwView.Height Or p.Top < (0 - p.Height) Or p.Left < (0 - p.Width) Or p.Left > pnlTwView.width Then
            p.RemoveView
        Else
            Log(p.Top & "_ "&p.Top)
        End If
    Next
End Sub

And this is the error:

I finally got the issue. In the for loop, after removing the view, change the value of pnltwview, so i got an error when i try to see log of last view.
Finally is my code:

For i = pnlTwView.NumberOfViews-1 To 0 Step-1
Dim p As Panel = pnlTwView.GetView(i)
    If p.Top+3 > pnlTwView.Height Or p.Top < (0 - p.Height) Or p.Left < (0 - p.Width) Or p.Left > pnlTwView.width Then
   p.RemoveView
   End If
Next
