Unfortunately you'll have to find and download a previous version of joiplay (as an APK) and make sure your auto updates are turned off. I'm not 100% sure if you need a previous version of the Renpy plugin but I used a previous version just to cover all bases. Works just fine for me after this, hopefully it helps.
For future reference, you don't need an older version of the plugin. Just tested it now and it opens.
Edit: testing it further, looks like it may not work
Edit2: Ok, looks like rolling back to an older version of the plugin may be necessary. Otherwise, you continuously get errors. Rolling back to the previous version gives you an error screen when loading in, but ignoring it resumes gameplay as normal.
