title: Subsequent Launch after uncalled onDestroy shows a blank screen
body: <p>I am using a <code>WebView</code> in my app's sole <code>Activity</code>. Whenever the user clicks on the BACK button, I override the <code>onKey</code> and process some clean up before calling <code>finish</code> of the activity.</p>
  
  <p>I see that once in a while (maybe 1 out of 20 times), <code>onDestroy</code> is not called. And in this case, if I launch my app again, a blank screen comes up. The Activity's <code>onCreate</code> is not called, and neither is my overridden Application's <code>onCreate</code>.</p>
  
  <p>Does anyone know why this happens, and are there any possible solutions?</p>
  
  <p>Thanks,<br>
