title: Android AsyncHttpClient, unable to find symbol class Header
body: <p>I'm trying to create asynchronous rest call in <a href="http://loopj.com/android-async-http/" rel="noreferrer">Android using a library <code>com.loopj.android.http.AsyncHttpClient</code></a> however, i'm unable to implement AsyncHttpResponseHandler's overridden methods because Android Studio cannot find an appropriate import for <code>Header</code> class</p>
  
  <p><strong>How can I resolve the issue with the Header class not recognized by the Android Studio IDE?</strong> </p>
  
  <pre><code> public void onSuccess(int statusCode, Header[] headers, byte[] response) {
                  // called when response HTTP status is "200 OK"
              }
  </code></pre>
  
  <p>I see that if I mouse over and click on the Header, I get the following message, but I don't know how to select one of the multiple choices in this menu (moving the mouse dismisses it)</p>
