resultCode is 0 (e.g. Activity.RESULT_CANCELED) when SMS message is successfully sent on Android

When I test on my Android device but when the SMS is sent then the resultCode is always 0 (e.g. Activity.RESULT_CANCELED). Any ideas why?

I log the resultCode in the onActivityResult method.

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
      if (resultCode == Activity.RESULT_CANCELED) {
        Log.i("APP", "SMS CANCELLED");
      }
      super.onActivityResult(requestCode, resultCode, data);
      SendSMSPackage.getInstance().onActivityResult(requestCode, resultCode, data);
    }

I'm getting this when trying to send to multiple recipients (using Gazfay's code here that fixes a bug with sending to multiple - #35), though a single recipient seems to work fine
