我有一個activityResult，但它的代碼不執行

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data); 
     if(requestCode == 0) { 
      finish(); 
     } 

     // Pass on the activity result to the helper for handling 
     if (!mHelper.handleActivityResult(requestCode, resultCode, data)) { 
      // not handled, so handle it ourselves (here's where you'd 
      // perform any handling of activity results not related to in-app 
      // billing... 
      super.onActivityResult(requestCode, resultCode, data); 
     } 
     else { 
      Log.d(TAG, "onActivityResult handled by IABUtil."); 
     } 
    }

purchaseFlow是從樣本代碼。我該如何修復它？
