title: Android Twitter Login button not working
body: <p>I'm writing an application that includes a sign in with twitter button. The button is okay. It shows on the screen when I click I give auth but I cant save the token and secret to a string variable. I mean it is empty always.
  The code at the below has been created by fabric.io automatically and I have added some stuff in it but it is not working. There is no error it just doesn't change the variable token and secret. I have tried this by an TextView object that changes in the success case and it never changes.
  What should I do?
  I just want to save token and secret to get user's information another time.</p>
  
  <pre><code>loginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button);
      loginButton.setCallback(new Callback&lt;TwitterSession&gt;() {
          @Override
          public void success(Result&lt;TwitterSession&gt; result) {
              System.out.println("Okay we are logged in now!");
  
              TwitterSession session = Twitter.getSessionManager().getActiveSession();
              TwitterAuthToken authToken = session.getAuthToken();
              token = authToken.token;
              secret = authToken.secret;
              String answers = "";
              User user = new User(userid,token,secret,answers);
              registerUser(user);
              twitterauth = true;
          }
  
          @Override
          public void failure(TwitterException exception) {
              // Do something on failure
          }
      });
  </code></pre>
  
  <p>EDİT:
  I'm taking an error like the following, if I click the sign in with Twitter button again:</p>

  <p>All I want to do is simple to start a new activity when "success" happens automatically.</p>
