Error occured during sliding at 7'th picture of 8 loaded by this code:

B4X: 
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("1")
    Slider.activityHasActionBar = False
    Dim sc As SliderContainer
    sc.Initialize
    sc.slider = Slider
    sc.items.Initialize
          
    For i = 1 To 8
        sc.items.put(LoadBitmap(File.DirAssets,"_" & i & ".jpg"),"Item " & i)
    Next
  
    sc.slider.SetImages(sc.items)
    sc.slider.SetZoomPanel(Activity)
End Sub

This message is just for reference - now i understand that lib can have tons of such unknown error, and always it needs to apply to the lib author.
So, i prefer to use classes that can be debugged and customized.
Anyway, thanks for the lib.

Error log doesn't have any useful information. So can you post your project?

You can always extract the class from b4xlib and can modify it. Its comparatively easy to store and include a b4xlib in a project rather than a class file.
