This game does not have an Android version. It can be played on Android using emulation with Joiplay. There are instructions above on this web page under the heading “How to play on Android”.
Like the instructions say, it is necessary to use “Joiplay 7.7.1 and the Ren’py plugins”. To find out where to get that version of Joiplay, see FAQ page in the Wiki.
If it still fails, try looking for Youtube videos on how to install Renpy games on Android.
