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.

I am stuck I don't how to proceed

TwitterService.java 
public class TwitterService extends Service {
  TwitterClient twitterClient = new TwitterClient(); 
  private TwitterThread twitterThread;
  @Override
  public void onCreate(){
  }
  @Override
  public void IBinder onBind(Intent intent) {
    return null;
  }



  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);

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

      }
    });
  }
}
