Would you mind showing the error? The android versions has been known to unfortunately be incompatible with some people's phones. We do plan to post a Google Play version soon as well, so if you are unable to get the game through itch, you can try Google Play.
So I unfortunately do not know why it's giving you that error, but the game is uploaded now on Google Play so please feel free to try and see if you can download the Google Play version!
