Android ports of RenPy games are ALWAYS hit or miss. Trying to get renpy to run on android is jank as fuck. Always will be. Android run on the Java platform, RenPy work on Python. They don;t like to work together. It is quite literally a hack that an android build can even be made in the first place and MOST have issues unique to android. Many devs just don't want to try to offer error support to android users because it;s an absolute pain to try to fix or even diagnose issues. IF a dev offers an android port it is as a courtesy. NEVER expect such ports to even work, and if they don't do not expect error support.
