UpiTransactionResponse.android(String responseString) {

  // Consider the response to be failure if success or submitted is not explicitly returned.
  this._status = UpiTransactionStatus.failure;
  List<String> fragments = responseString.split('&');
  fragments.forEach((fragment) {
    List<String> keyValuePair = fragment.split('=');
    String normalizedKey = keyValuePair.first.toLowerCase();
    String value = keyValuePair.last;
    switch (normalizedKey) {
      case 'txnid':
        this._txnId = value;
        break;
      case 'responsecode':
        this._responseCode = value;
