----------------------------------------------------------이거 추가하면서 에러 뜨네요 다른곳에는 잘들어가던데

이거 넣을때 무슨 조건이 있어야하나요

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
 switch( keyCode ){
 case KeyEvent.KEYCODE_BACK:
 case KeyEvent.KEYCODE_HOME:
  return false;
 }
 return super.onKeyDown(keyCode, event);
   }
}

이렇게 뜨는데요 이게 어떻게 고쳐야 될까요 다른곳은 잘되던데 여기만 안되더라고요
