Confused by "Sorry! The application ____ (process ___ ) has stopped unexpectedly..." message

 i, folks:

I am really confused about Android at this point. I'm writing a very
simple application called "Counter" (a starting point) that uses a
drawabl PNG image and no matter what I do, when I run it in the
emulator, I get this annoying message:

"Sorry! The application Counter (process mine.counter) has
stopped unexpectedly. Please try again. [Force close buttton]"

All I want my application to do is to display a Drawable called
"n0.png" which I have defined to my "rsc\drawable" folder.

I've looked at other sample applications, including the ones in the
SDK and tried emulating the coding, without success. I'm very
confused about how the Java, XML, and other files interact. I just
don't see why the program is freezing when I've practically followed
the structure of other applications to the letter.

Below, I've replicated the code. Thanks for any help you can provide.
