Minecraft PE Crashing

I have uninstalled and reinstalled. Minecraft crashes after the white screen. Or if I try to create a land, it crashes on the loading/generating landscape screen. Or it crashes when I try to load  an already created land. Or it crashes when I try to join someone else’s land. Basically I can’t even play Minecraft at all anymore. Every now and a again it’ll re-load saying “global resources reset a crash was detected”
