I include photos with 4 resolutions and two languages, so I made the following folders:
drawable-en-hdpi
drawable-en-ldpi
drawable-en-mdpi
drawable-en-xhdpi
drawable-es-hdpi
drawable-es-ldpi
drawable-es-mdpi
drawable-es-xhdpi
... and in fact, it works, but the problem arises when I need to include some images that do not require language, I mean pictures without text. The first way was to include them in a shared folder with a choice, but Android does not allow me to do this, and finally I had to duplicate these images, I mean, include them in the folders drawable-enand drawable-es. I have no idea why this happens, but it seems that if you must add all the images that are used in all language folders.
Thanks in advance.
