Finally, when we click on the Button it should update the Twitter feed. Inside the 'onClick' method, create and send a Message to your Handler.

where did I go wrong?

MainActivity.java 
public class MainActivity extends Activity {
  Button button;
  TwitterClient twitterClient = new TwitterClient();

  @Override
  public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_main);

    final TwitterThread twitterThread = new TwitterThread();
    twitterThread.setName("TwitterThread");
    twitterThread.start();

    button = (Button) findViewById(R.id.update_button);
    button.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick (View v) {
       Message message = Message.obtain();
       twitterThread.twitterHandler.sendMessage(message);
        }       
      }
    }
  }

  class TwitterThread extends Thread {
    public TwitterHandler twitterHandler;
    @Override
    public void run() {
      Looper.prepare();
      twitterHandler = new TwitterHandler();
      Looper.loop();
      }
  }
  class TwitterHandler extends Handler {
    public void handleMessage(Message msg) {
    twitterClient.update();
    }

  }
}

try adding an @Override before the handleMessage in the TwitterHandler class.

I had everything you had and also the @Override and it accepted my solution.
