That's... I don't know. Have you tried other versions of the Android build before and do they work?

I asked my friend and... I really don't know. Apparently, it might be an issue with Ren'Py or something and said
"I think that that's just Ren'py. the only thing we can do is wait for Ren'py itself to fix it and then compile an Android build with the new version."
I'm really sorry but I don't know what's happening. :\
