Hey, i wanted to update y'all since this post is kind of outdated. Joiplay and Renpy addon weren't available on the play store anymore. So here are the links to download them that are safe.
Renpy addon (newest version as of 8.12.23)
Both of these are specified on the Joiplay website but I know you're probably lazy and won't go out to find them. So here you go. (No offense) Enjoy.
