꼭!!! 다이얼로그를 onDestroy에서 dismiss 시키는 버릇을 만들자~

제목 대로 안드로이드에서 다이얼로그를 만든 후, dismiss를 시키지 않고 Activity를 종료한 후,

WindowManager를 이용하여 addView를 추가 시키고자 할때 아래와 같은 에러 메세지를 보이게 된다.

@Override

 protected void onStop() {

  super.onStop();

  if (loadingDlg != null) {

   loadingDlg.dismiss();

   loadingDlg = null;

  }

 }

위와 같이 onStop 부분에 다이얼로그를 dismiss 시키는 버릇을 들이자.
