So Android Studio now have this mipmap folder where you should have your images with multiple resolutions (mdpi, hdpi, xhdpi, xxhdpi).
Using Simple-Nine-Patch-Generator i get my let's say photo.9.png.
I am trying to set background to view, but i can only link to images from drawable folder. I have my multiple photo.9.png in my mipmap, when trying to type @mipmap/ autocomplete offers @mipmap/photo.9. But there is error (. [dot] is not valid char). When typing @mipmap/photo i get again get error (can't resolve symbol '@mipmap/photo').
I can only link .9.png from drawable folder, but i can't make multiple resolution of same image in drawable.
