title: notifyDataSetChanged() doesn't update ListView
body: <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) {
          if (resultCode == RESULT_OK) {
              deserializeQuotes();
              quotesAdapter.notifyDataSetChanged();
          }
      }
  </code></pre>
  
  <p>My array clearly has been updated, and I can see the change when my app starts, but why doesn't it update in this method? The code enters this method.</p>
