I can't handle the message... Handle It! Code Challenge Task 3 of 3.

public class MainActivity extends Activity {
  Button button;
  TwitterClient twitterClient = new TwitterClient();
  String customMessage = "EarthBound is the best RPG of all time!";

  @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();
//Don't know what to do here
        twitterThread.tch.handleMessage(message);

      }
    });
  }

  class TwitterThread extends Thread 
  {

    public TwitterClientHandler tch;


    @Override
    public void run() 
    {
      Looper.prepare();
      tch = new TwitterClientHandler();
      Looper.loop();

    }
  }

  class TwitterClientHandler extends Handler
  {
    @Override
    public void handleMessage(Message msg)
    {
      twitterClient.update();
    }

  }
}
