My code won't run

I am learning the android Ribbit track. The only thing I changed was the application name. (I named it TextMe) When I try to run the app it says "TextMe has stopped". This is my logcat:

Nothing is jumping out to me from there.

Which part of the Ribbit app were you most recently working on? If you can upload your project to Github or similar, I could take a look.
