title: Error in SWT/LogCat? or Android 2.2 AVD
body: <p>Based on a tip, I changed the target of my Android app from 2.3 to 2.2.</p>
  
  <p>Out of the frying pan and into the fire!</p>
  
  <p>Now my app won't even open (in the 2.2 emulator) and I get this (seems to be an SWT problem, and then an android/LogCat problem):</p>
