In trying to diagnose where my Annotation problem was I wasn’t getting the full stack trace and hence didn’t know exactly where the problem was. After stumbling around one why I found a way to get the full stack trace; run the application from Eclipse in Run mode rather than Debug Mode:

% emulator &
% adb logcat

Then in Eclipse ran the application the application using Run. A message on the emulator UI says; “An error has occurred in process com.saville.tests … <Force Quit>”. And then in the logcat trace we see the full backtrace.
