title: Cursor.moveToNext without moveToFirst
body: <p>Will the next code work as expected?</p>
  
  <pre><code>Cursor c = db.query(tableName, requestedColumns, condition,
          conditionParams, null, null, sortOrder);
  while(c.moveToNext())   {
       //do stuff with rows
  }
  </code></pre>
  
  <p>The examples I found so far suggest calling <code>c.moveToFirst()</code> prior looping, but is it really necessary?</p>
