when i tried to put an external server,the game crashes

When i tried to press done after putting a adress it crashes

*What I expected to happen was that the adress it crashes.
I thought should work,but ot didn't.

*What actually happened was after pressing the "done" button or the back arrow it crashed and closed the app.
I was trying to add a server,but after a few tries to put the adress i gave up.

Steps to Reproduce:
1. First,try to press the "done" button or the back arrow
2. Later,the screen will turn black for a second
3. Finally,you are outside the app and i think it said "Minecraft PE stopped working" or something.
