Whenever I load my worlds on my kindle fire, all of Minecraft just crashes.

I opened one of my Minecraft worlds day b4 yesterday and then again today. It crashed again and again while it was on the loading page and when I was in my world. This continued on for a very long time. I tried doing everything I could think of to fix the problem, but nothing I tried to do seemed to work. Hard closing the game didn't help. Neither did deleting the game and resigning into my account. I also tried rebooting my kindle fire and that did not solve the problem either. What can be done to fix that?
