I’m sure you’re dealing with resource precedence used for selection.
If you provide folders:
layout-sw600dp-*
values-large-*
values-sw600dp-*
Android is not obliged to match values selection folder to those of layout, rather it uses same precedence logic separately for layout and separately for values folder.
You can learn about this selection algorithm here:
