Hey Steve Hunter , long time. I don't understand my error message? What am I doing wrong? Thanks

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){

      }
    });
  }

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

Have you deleted the TwitterThread class? You should leave that in but delete, or comment out, the update() call:

  class TwitterThread extends Thread {
    @Override
    public void run() {
      //twitterClient.update();
    }
  }

So, your whole file after task one looks like this, most of which you haven't altered at all:

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){

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

  class TwitterThread extends Thread {
    @Override
    public void run() {
      //twitterClient.update();
    }
  }
}
