Nothing's wrong with the game. Thousands of people have gotten these same exact files to work.
Play it on PC if you're able, if not, follow the instructions.
The issue is related to your phone's settings. You need to directly enable "unsigned" apps to run on your phone. I've done this hundreds of times now by people who claim it doesn't work and, when they follow the steps outlined in the post I linked you to - works fine.
Otherwise, I can offer you a refund. Not much besides that I can do for you.
