I ran into this problem a while ago for a different game, what I found worked was going into your file manager finding the zip file you just downloaded, then renaming it so instead of a .zip its a .apk
I think that may have worked! I changed the name (oddly enough it already had .apk at the end of the name just wouldn't do anything) but I changed the name and hit "open with" and now it says its preparing so I'm hoping its working!
