I think you just
1. install Joiplay (and renpy plugin) on the android device (like 30+40 MB),
2. download and unpack Windows version,
3. create shortcut using the exe file, launch and play
I used it and it worked on Headmaster and some other games. They boast 90% compatibility for renpy. But Play Market version is very old and bugged, there is a new version 1.20 on patreon and site.
APK would prefer owners of some older devices with smaller memory capacity - for example, HM weight over 6 gigs! So there is always some demand for compressed versions, heh. Overall, positive experience, no crashes experienced, saves are easily accessible.
