Unable to load my city.

This morning my game would not load on my android. It crashed 4 times in a row, I have plenty of free space on my phone so that is not the issue. I uninstalled it, restarted the phone, then reinstalled the game. After inputting my date of birth, the game dutifully starts to load the tutorial but immediately crashes again. I have been playing since March of 2015 so I have a lot of time invested in my city. I do not believe my device is the problem. My question: is there an update issue or a server issue that is at fault? Any information will be of help. Thanks.
