When I had the exact same problem (on iOS), I had figured out that if the startup goes longer than 20 seconds then the game automatically crashes. What I did to counter this was to go into the app, lock the device, then wait a while. Afterwards I went back into the game, and most of the time it let me in. If you don't have an account, try to make one when you get into the game using this. Note that the locking strategy doesn't always work, but it's always worth a try.

Also, RobTop mentioned that performance issues like these would most likely be fixed in Update 2.0.
