I tried creating the android pack once, but the Ren'py button build Android button is still grey out after I installed JDK.
I think some people mentioned (joiplay android ren py emulator) could make the game work on android. If anyone wants to play on their phone, you can use this.
Personally, I don't have an android device, so I can't check if it could work. And, any bug found on android is out of my reach to fix. So, I think in short term, I wouldn't provide android version.
