Welcome!
This is a bit of a side note: There are some
very roundabout ways of getting
some android apps running on r-pi 4 (not sure about Stardew, like using specific OS's for installing and running, Emteria OS, LineageOS, instead of Debian/pi OS, then legit buying and running the Android version via the Google Play store, or F-Droid to connect to play store) but these can be a process and no idea what problems I might encounter and which apps will run. I'd definitely curious though!
I only mention it because I was mucking with this recently on a pi-3, it was not very practical and performance was still likely going to be an issue, so I hung it up part way through (if I get bored enough again i might try again just for nerd kicks more than a real desire to play it on pi). I'm hoping to upgrade to pi-4 or maybe that pi 5 will come sooner than I think, and somehow I can get it over there and running smoothly-ish (paid of course) with Android version, since it's my arcade for lots of other stuff. I still want to try it on pi-4 since the specs are better than my 3... but no idea if I can get it running on any pi, so doesn't justify the upgrade yet--probably trying it is the only way I'll know for sure. On the bright side, I don't own a single Android device and now I have a copy of paid Android Stardew in addition to PC, and iOS lol... I guess I'm squirreling it away for the day where I ever end up with another Android tablet.
If I ever manage to get it going on r-pi, I'll try to remember to post about it. I'm no pro at this or anything though, so maybe I'll fail miserably lol.
