I did say what the error was: Application stopped unexpectedly. The code as above runs perfectly fine and I should note this code is based on Google's Notepad tutorial, except it only had one group. I had the same 1 group setup in my app, but the code (as represented in ListView/TextView group 2) kept failing with that generic error. So, I opened a working tutorial project and copied it over into my XML file (group 1). As soon as I did that, the app worked fine, spitting out two lines on-screen.
What I don't get is why, if you take out the first ListView/TextView group, then emulator bombs with that generic error. Eclipse provides no insight as to why.
