Minecraft pocket edition will not open.

When I go to open Minecraft pocket edition all you see is a black screen. Then a box pops up saying unfortunately, Minecraft pocket edition has stopped working. I have tried Uninstaller the game. Re installing it again. I cleared the cache. I have restarted the device. I have made sure my device it up to date on updates. I have cleared the files on my device. The problem is still not fixed.
