How can i run method from B4A that is in library jar file?
I have B4AGallery that is fantastic library but i need to clear list items before inserting new one items. I found that i need to call this:

package:
it.giuseppe.salvi.library.photogallery.adapter
public class:
PhotoGalleryBaseAdapter
Function:
public void Clear()
{
itemsView.clear();
notifyDataSetChanged();
}

I try it this way but when running apk i get error.

B4X:

    Dim args1(1) As Object
    args1(0) = True
    Dim r As Reflector 
    r.RunStaticMethod("it.giuseppe.salvi.library.photogallery.adapter.PhotoGalleryBaseAdapter" , "Clear" , args1, Null)

So i don't know how to call this public function in B4A using reflector.

Dim r As Reflector

dim r as Reflector
r.Target = gallery

r.RunMethod("Clear")

    Gallery.ItemHeight = 436
    Gallery.Spacing = 50
  
    Gallery.ScaleType = Gallery.ScaleType.Center_Crop
    Gallery.SetNoEffect = False
    Gallery.SetBorderColor=Colors.Yellow
    Gallery.SetCornerRadius = 10
    Gallery.SetBorderWidth = 2
    Gallery.SetOval = False

    'TARGET IS GALLERY --> PHOTOGALLERY
    r.Target = Gallery
