This is the Java code how can we implement this in Kodular

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case UPI_PAYMENT:
            if ((RESULT_OK == resultCode) || (resultCode == 11)) {
                if (data != null) {
                    String trxt = data.getStringExtra("response");
                    Log.d("UPI", "onActivityResult: " + trxt);
                    ArrayList<String> dataList = new ArrayList<>();
                    dataList.add(trxt);
                    upiPaymentDataOperation(dataList);
                } else {
                    Log.d("UPI", "onActivityResult: " + "Return data is null");
                    ArrayList<String> dataList = new ArrayList<>();
                    dataList.add("nothing");
                    upiPaymentDataOperation(dataList);
                }
            } else {
                Log.d("UPI", "onActivityResult: " + "Return data is null"); //when user simply back without payment
                ArrayList<String> dataList = new ArrayList<>();
                dataList.add("nothing");
                upiPaymentDataOperation(dataList);
            }
            break;
    }
}

private void upiPaymentDataOperation(ArrayList<String> data) {
    if (isConnectionAvailable(MainActivity.this)) {
        String str = data.get(0);

                    status = equalStr[1].toLowerCase();

                }
            }
            else {

            }
        }

        if (status.equals("success")) {
            //Code to handle successful transaction here.
            Toast.makeText(MainActivity.this, "Transaction successful.", Toast.LENGTH_SHORT).show();

        }

        }
        else {

        }
