If it stops half way, it most likely means you need more space on your phone if I were to guess. Does it say any specific error when it stops?
No it doesn't it just doesn't work I click on it and it doesn't even open it just says it unfortunately stopped and I have plenty of space I don't know what else to do?
How much space do you have available on your phone? I just tried it myself and was running into the same problem, but after I freed up about 700 MBS on my phone it worked without a hitch. The game itself isn't a big file, but I guess Android requires a lot of extra space. Let me know if that works for you.
