We will be supporting Android forever, but for v0.20 we are trying to reduce the apk's size greatly as it's nearly at the 2GB limit, so it's possible there may be some delays specific to the Android version. Some devs with very large games use a third party app on Android that allows you to play Ren'Py games (Joiplay and the Ren'py plugin), so we might look into that as well.
