How to adapt drawable for different aspect ratio screens?

With a ratio of 16:9 all clear — posted in resources folders ldpi, mdpi, hdpi, xhdpi, xxhdpi. But if the app starts on the screen 16:10, for example, the resolution 768х1280, the background is stretched.

How to specify Android (roughly speaking how to name drawable folder) in order for such permits (with a width of 768, 1200, etc.) it picked up the correct background? Resize background (768х1280), import it in the folder drawable-sw768dp-xhdpi, the forms designer it loads correctly, but in the emulator it still loaded from the folder drawable-xhdpi (720h1280) and therefore stretched.
