title: Querying android calendar retrieves even deleted events
body: <p>I am using below mentioned code to retrieve all the events from all the calendars saved in the android's native calendar application. Now if I delete certain event from the native calendar, still my code fetches and shows that event. How can this be possible. Does it set some delete flag instead of actually deleting the event. </p>
  
  <pre><code>Cursor cursor = cr.query(Uri.parse("content://com.android.calendar/events"),
                      projection, selection, selectionArgs, null);
  </code></pre>
