"the mod is not being added to the game because it is in an empty folder"

[Kizzo]

I've been trying to figure out what's wrong for a few hours now and I can't figure out what. I'm not very good at messing with these things, but I tried to download a portraits mod (the villagers something), but it appears that it is in an empty folder and the mod cannot be added (I don't even know what that means) I tried to see other questions here but I couldn't understand anything. Pls help.

I play on my cell phone.

My log (in case this might help)

SMAPI log parser - SMAPI.io

The mod is named 'png,' so it’s possible the files are just loose PNG images, which SMAPI can’t load. You need a mod like Portraiture to load PNG files properly.
