Thank you so much Steve and Mark for your replies.  It is helping me
understand how to read the logcat output better.  :)
 
I put a breakpoint on line 42, but it still crashed when I ran it with the
breakpoint.  Is that the same as a debug point?

Hi tinyang,

If you're using eclipse, you can put a debug point at line 42 in
CameraPreview and see what object is null that you're trying to call a
method on.

You are already seeing them. The more refers to the lines that are just
duplicates of the lines that the RuntimeException exception above the
NullPointerException has already printed.
