  /** Called when the activity is first created. */  @Override  public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.main);

      buttonPlayPause = (Button)findViewById(R.id.playpause);      buttonQuit = (Button)findViewById(R.id.quit);      textState = (TextView)findViewById(R.id.state);
