Just tried to install this on android and the game doesn't run even with all the extra added apps. Even Google is cracking down on this as many have used such extra apps for nefarious purposes. . With Ren'Py having its own android development engine I don't see why you can't just make an android version without all the extra steps like the other game developers here do.
Even the reviews of JoiPlay are saying that it is a substandard app to play Ren'Py games and makes them lag worse than using Ren'Py itself to make all the needed changes to run on android.
I'm not aware of any other way to release Harem Hotel on Android.
Feel free to ask questions though, like "Why can't you release an android version like all the other developers?"
The answer to that would be that Harem Hotel is over 90 Gigabytes. The game has already been drastically compressed down to 10GB, and even with that, your android phone will only run .apks under 2GB. As far as I know, it is still impossible to make an .apk bigger than 2GB. It would be nice if .apk caught up to the modern year, but since Harem Hotel is big, it must be emulated on Joiplay.
Please let me know when/if you can get Harem Hotel to run on your phone without Joiplay.
As far as I know some apps with more than 2gb space do run on android devices,like i played a 4.6 gb+ game years back on my android phone,so that thing of not supporting 2gb+ apps is new for android,i guess, maybe it will work in old android devices?
And one more thing i founded that if you compress your files and release them as .zip they can be changed into .apk files after being downloaded on any device and can be installed and run on any android device.
