Hi guys, I'm new here, and from what I can tell so far this website is an amazing resource.

Anyway, I've been reading up on Java and Android development for a little while now, and today decided to attempt to create a very simple calculator in order to try to get a hang of it. Well, for the most part everything had been going well, up until I realized that what I thought would work in altering the TextView ends up force closing the application before it ever displays anything on the screen!

Here is what I have so far:
(MainActivity.java)


(activity_main.xml)


I've been ripping my hair out trying to figure out why this is occurring. I've scoured through web pages and tutorials with very little luck, I'm hoping you guys can help me spot the issue!

Thanks in advance!
