title: after update: "SQLiteException: unable to open database file"
body: <p>why wouldn't there exist a SQLite database after the app was updated to a new version ? How is it possible that the database is no longer present even though it did exist earlier.</p>
  
  <p>(using Android 2.3.3)</p>
  
  <p><strong>Error Log</strong>
  why would SQLiteOpenHelper.getWritableDatabase() cause this exception? Surely it would be clever enough to realize "oooh the db doesn't exist, let's create it!</p>
  
  <p>note that the <code>new SQLiteOpenHelper(context)</code> worked OK as far as I can tell. However, I do not know whether <code>onCreate()</code> or <code>onUpgrade()</code> were triggered.</p>

  <p>After I trap the exception "SQLiteException: unable to open database file", should the app simply try to instantiate another SQLiteOpenHelper ?</p>
