I couldn't understand this can you please help me?

It talks about overriding oncreate method. We cant do this in TwitterService class and in MainAcitivty there is already one. Challenge was this: Let's switch to updating our Twitter app from within a Service. Start by creating a new TwitterThread field, and starting it in the 'onCreate' method. You'll need to override the 'onCreate' method.

TwitterService.java 
public class TwitterService extends Service {
  TwitterClient twitterClient = new TwitterClient();    

  class TwitterThread extends Thread {
    TwitterHandler twitterHandler;
    @Override
    public void run() {
      Looper.prepare();
      twitterHandler = new TwitterHandler();
      Looper.loop();
    }
  }    

  class TwitterHandler extends Handler {
    @Override
    public void handleMessage(Message msg) {
      twitterClient.update();
    }
  }
}
MainActivity.java 
public class MainActivity extends Activity {
  Button button;   

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

   TwitterThread twitterThread = new TwitterThread();
    button = (Button) findViewById(R.id.update_button);
    button.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v){

      }
    });
  }
}

Hey Sena!

Services DO have onCreate methods, and you can override it like this:

  @Override
  public void onCreate() {

  }

Hope that helps!
