title: Twitter4j authentication credentials are missing
body: <p>I would like to make a tweet with Twitter4j in my Android app. Here is my code:</p>
  
  <pre><code> //TWITTER SHARE.
  @Click (R.id. img_btn_twitter)
  @Background
  public void twitterPostWall(){
  
      try {
  
  
          //Twitter Conf.
          ConfigurationBuilder cb = new ConfigurationBuilder();
          cb.setDebugEnabled(true)
                  .setOAuthConsumerKey(CONSUMER_KEY)
                  .setOAuthConsumerSecret(CONSUMER_SECRET)
                  .setOAuthAccessToken(ACCESS_KEY)
                  .setOAuthAccessTokenSecret(ACCESS_SECRET);
  
          TwitterFactory tf = new TwitterFactory(cb.build());
          Twitter twitter = new TwitterFactory().getInstance();
          twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
  
          try {
              RequestToken requestToken = twitter.getOAuthRequestToken();
  
              Log.e("Request token: ", "" + requestToken.getToken());
              Log.e("Request token secret: ", "" + requestToken.getTokenSecret());
              AccessToken accessToken = null;
  
  
          }
  
          catch (IllegalStateException ie) {
  
              if (!twitter.getAuthorization().isEnabled()) {
                  Log.e("OAuth consumer key/secret is not set.", "");
              }
          }
  
  
          Status status = twitter.updateStatus(postLink);
          Log.e("Successfully updated the status to [", ""  + status.getText() + "].");
  
      }
  
      catch (TwitterException te) {
          Log.e("TWEET FAILED", "");
  
      }
  }
  </code></pre>
  
  <p>I always get this error message from Twitter4j: java.lang.IllegalStateException: Authentication credentials are missing. See <a href="http://twitter4j.org/en/configuration.html" rel="noreferrer">http://twitter4j.org/en/configuration.html</a> for the detail. But as you can see I'm using builder to set my key. Can someone help me to fix it please? thanks.</p>
