I looked through this code. I didn't try to run it since it looks like
I'd need your layout xml as well. I'm pretty sure something in your
onCreate of TeaTime is causing this due to what your error says
(Unable to resume activity). The stack trace might tell you where the
problem is in your code, although sometimes you'll get a null pointer
exception thrown from code in the android api. You could also probably
step through it with a debugger if you wanted.
