body: <p>I have been trying to add a new user to quickblox referring to the code provided in the sample-chat provided for android.</p>
  
  <p>I am using the following code.</p>
  
  <p>Authenticate using APP_ID,AUTH_ID and SECRET_ID.</p>
  
  <pre><code>QBSettings.getInstance().fastConfigInit(APP_ID, AUTH_KEY, AUTH_SECRET);
  </code></pre>
  
  <p>Create an application session</p>
  
  <pre><code>QBAuth.createSession(new QBEntityCallbackImpl&lt;QBSession&gt;() {
  @Override
              public void onSuccess(QBSession qbSession, Bundle bundle) {
                  getAllUser();
              }
  
              @Override
              public void onError(List&lt;String&gt; errors) {
                  // print errors that came from server
                  DialogUtils.showLong(context, errors.get(0));
                  progressBar.setVisibility(View.INVISIBLE);
              }
          });
      }
  
  //Sign up a new user
  
  // Register new user
  
  final QBUser user = new QBUser("userlogin", "userpassword");
  
  QBUsers.signUp(user, new QBEntityCallbackImpl&lt;QBUser&gt;() {
      @Override
      public void onSuccess(QBUser user, Bundle args) {
          // success
      }
  
      @Override
      public void onError(List&lt;String&gt; errors) {
         // error
      }
  });
  </code></pre>
