Apps Lost in Ch 6 of "Learning Android"

[GTbrewer]

EDIT 10 May 2011 0650 CDT: This part of the post is no longer relevant. I found and fixed the error that
was causing the errors here using diff to compare my code vs the online code from the book. The question
now involves the Eclipse errors (at least, they *LOOK* like internal Eclipse errors to me) in my follow-up
post below. Then again, the author DID say there would be errors...maybe it wasn't supposed to build
yet.

[no longer relevant, so I nuked this part to avoid wasting space here --jim]

Ok, I did a few diffs, comparing my code to the book's code (nice having it online!), and found this typo:
<TextView android:id="@+id/textView" -android:layout_height="wrap_content"
^
That '-' isn't supposed to be there. That, and things like android.layout_height and _width, etc.,
weren't in the same order, but I can't imagine that being a problem. So apparently, that one '-' killed
everything from that point forward. It shows no errors now, but when I try to build it, I get the following,
which *REALLY* don't understand:

UNEXPECTED TOP-LEVEL EXCEPTION:

Can anyone translate this and point me to either the problem or TFM for me to 'R/ead?
