title: Adjust user agent in Android with Volley
body: <p>I am wondering how to adjust the standard user agent in my http requests. I am using the Volley library and I KNOW how to</p>
  
  <ul>
  <li>set a new user agent</li>
  <li>retrieve the default user agent as a string (e.g. "Dalvik/1.6.0 (Linux; U; Android 4.0.2; sdk Build/ICS_MR0") => System.getProperty("http.agent")</li>
  </ul>
  
  <p>What I DON'T know is: </p>
  
  <ul>
  <li>how to get the single elements this user agent is build of, so I can replace only the string "Dalvik/1.6.0" with a custom string.</li>
  </ul>
  
  <p>Is that possible, or do I have to make a string replacement?</p>
  
  <p>Thx</p>
