title: How do I use the Volley network request queue?
body: <p>I <code>.add(</code> new network calls to my Volley Request Queue which I have created as a singleton as suggested. But I always immediately <code>.start()</code> these network calls. This is always done as an action in an activity or a fragment.</p>
  
  <p>The <code>add</code> method cannot even be chained into a <code>start</code> method, like <code>.add(new volley request).start()</code></p>
  
  <p>So this assumes I am actually managing (or wanting to manage) a network queue somewhere, outside of the way Volley handles its queue, I guess. Should I be sending these things to an IntentService and listening for the IntentService to send a response back to my Fragment/Activity?</p>
