Hey there, I just started modding for Android in the last couple of weeks but I have figured some stuff out. What you need to look for mods that were uploaded no later than February 2020. I'm not exactly sure why this is a magic number, but it is. Early February is fine, late February generally is not. I've actually got a surprising amount of mods working including Medieval buildings, kind of half of hair mods? I don't understand why the whole thing doesn't work but I have some decent hairs now lol. I have more grasses, as well as a mod that prettifies grass, a really nice greenhouse mod, a mod that changes the towns look to match medieval buildings, a mod that gives me a bathtub as well as a new house layout, a mod that changes the look of trees, a mod that makes sprites a little cuter, a mod that makes a couple of the bachelor's cuter, like I said, a lot of mods. Feel free to message me and I'll give you the links to everything.
The magic date on the Wiki and other articles is actually December 21 , 2020. Even from December 20, 2020 you should be fine because as of that date there still was "no such thing" as SDV V.1.5. Side note: Yes, I'm sure there was a BETA release sometime before hand for mod authors to tinker with, but this is usually at the bottom of the page under the "Description" tab or directly on the file itself.)
Going back to December 21 2020 and its magic importance. This is because, if you guys follow ConcernedApe or SDV on a regular basis you'll know know that SDV 1.5 (ConcernedApe's final and probably the largest update to the game) was released on this date (December 21, 2020). Along with the fact that he [ConcernedApe] has begun a new game developing endeavor (Haunted Chocolatier), the 8 year partnership between ConcernedApe and Chucklefish has recently come to an end. So for a long, long, loooong while us SDV mobile players have been patiently waiting and wondering: "What the heck happened?!" C.A. has decided to self-publish his games (hence the end of the 8 year Chucklefish partnership) going forward which is what brings me to this: check out this link, I'm not giving ANY spoilers. It's at the bottom under the rest of my post.
I'm relatively new to modding as well and I use Android too (waaay to broke for a laptop rn). So I've been at it a few months but the going is slow, especially when it comes to "changing things up". I had a great set up of functional and aesthetic mods that all worked but then I got bored (ah the inevitable downfall of seemingly infinite modding options). So, I WAS using AOFB (Ali's Overgrown Fairy Buildings), More Overgrown Fairy Buildings, Overgrown Fairy Craftables; AOFB Shipping Bin, AOFB Tractor Garage; Foliage Redone — Foliage Only; Dirt, Grass, Cliffs, Water; Tractor Mod, Tractor Recolors, Way back Pelican Town (I dunno how, but it worked); Pegasus Horse; Time Speed; Generic Mod Config Menu; Country Garden Farmhouse V2; Mii's and Magmatica's Country Furniture; Industrial Kitchen; Industrial Furniture; Country Walls and Floors; Warm and Cozy Fireplace; More Flowery Grass; Elle's Seasonal Paths; Seasonal Fences; Gate Fix; among others. Don't forget to check "Nexus Requirements" under the Description tab of the mod you are interested in. You must download what ever is there unless it says (optional) beside it. If you don't, your Mod WILL NOT WORK. Some common requirement Mods are: Content Patcher; TMX Loader/Map toolkit; PYTK (Platonymous Toolkit); Shop Tile Framework; Producer Framework; Expanded Preconditions Utility...etc. Good luck and happy modding. They all worked, no red SMAPI error messages, perfection. I should have left it alone.
Here's the link that you must check out!

If anyone posts back I also have the link for the mods, I may add them in a week or so even if not. So be sure to check back or follow this thread. Thank you, and happy modding!
