Android Question ImageSlider problem exception divided by zero

[josejad]

Hi everyone:

I'm trying to use ImageSlider in my project, but when I call ImageSlider1.NextImage I get the error:

imageslider$ResumableSub_NextImageresume (java line: 368)
java.lang.ArithmeticException: divide by zero

In the same activity, I have a layout loaded, and I load another layout over the first one to show the pics.
I've tested in a new project just the imageslider, with the same folder and files, and it works, so the problem maybe with the two layouts?

Working project:

Sub ImageSlider1_GetImage (Index As Int) As ResumableSub
    Return xui.LoadBitmapResize(File.DirRootExternal & "/checklist/2900040_U09/", $"1.13(${Index}).jpg"$, _
        ImageSlider1.WindowBase.Width, ImageSlider1.WindowBase.Height, True)
End Sub

Sub Activity_PermissionResult (Permission As String, Result As Boolean)
    If Permission = rp.PERMISSION_WRITE_EXTERNAL_STORAGE Then
        ImageSlider1.NumberOfImages = 3
        ImageSlider1.NextImage
      
    End If
End Sub

Failing code (in this project I've checked the PERMISSION_WRITE_EXTERNAL_STORAGE in other sub)

Sub IVFotoPunto_Click
    ImageSlider1.NumberOfImages = 3
    Activity.LoadLayout("VisorImagenes")
    ImageSlider1.NextImage
End Sub

Sub ImageSlider1_GetImage (Index As Int) As ResumableSub
    Return xui.LoadBitmapResize(File.DirRootExternal & "/checklist/2900040_U09/", $"1.13(${Index}).jpg"$, _
        ImageSlider1.WindowBase.Width, ImageSlider1.WindowBase.Height, True)
End Sub

Thanks¡¡

Is ImageSlider included in VisorImagenes layout? If so then you need to set NumberOfImages after you load the layout.

so simple, so obvious... sorry, blinded for too many things.

Thanks¡¡
