Как интегрировать Paypal в приложение Android?

Я пытаюсь интегрировать paypal с Android-приложением, используя песочницу. Я получаю успешную работу с paypal, но когда я делаю платеж, экран будет невидимым напрямую без Response.
Как я могу получить ответ на указанный вопрос?

Это мой код.

private void invokeSimplePayment()
{
    try
    {
        PayPalPayment payment = new PayPalPayment();
        payment.setSubtotal(new BigDecimal(Amt));
        payment.setCurrencyType(Currency_code[code]);
        payment.setRecipient("Rec_Email");
        payment.setPaymentType(PayPal.PAYMENT_TYPE_GOODS);
        Intent checkoutIntent = PayPal.getInstance().checkout(payment, this);
        startActivityForResult(checkoutIntent, request);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

public void onActivityResults(int requestCode, int resultCode, Intent data)
{
    switch(resultCode) 
    {
        case Activity.RESULT_OK:
            resultTitle = "SUCCESS";                
            resultInfo = "You have successfully completed this " ;
            //resultExtra = "Transaction ID: " + data.getStringExtra(PayPalActivity.EXTRA_PAY_KEY);
            break;
        case Activity.RESULT_CANCELED:
            resultTitle = "CANCELED";
            resultInfo = "The transaction has been cancelled.";
            resultExtra = "";
            break;
        case PayPalActivity.RESULT_FAILURE:
            resultTitle = "FAILURE";
            resultInfo = data.getStringExtra(PayPalActivity.EXTRA_ERROR_MESSAGE);
            resultExtra = "Error ID: " + data.getStringExtra(PayPalActivity.EXTRA_ERROR_ID);
    }
    System.out.println("Result=============="+resultTitle);
    System.out.println("ResultInfo=============="+resultInfo);
}

Это мой код, и он отлично работает. Существует два класса.

Для PayPal из песочницы в живую среду вам нужно сделать 2 вещи: поместить фактического владельца учетной записи в установленного получателя и получить живой идентификатор, отправив ваше приложение в PayPal

public class ResultDelegate implements PayPalResultDelegate, Serializable {
     private static final long serialVersionUID = 10001L;


    public void onPaymentSucceeded(String payKey, String paymentStatus) {

        main.resultTitle = "SUCCESS";
        main.resultInfo = "You have successfully completed your transaction.";
        main.resultExtra = "Key: " + payKey;
    }


    public void onPaymentFailed(String paymentStatus, String correlationID,
                  String payKey, String errorID, String errorMessage) {
        main.resultTitle = "FAILURE";
        main.resultInfo = errorMessage;
        main.resultExtra = "Error ID: " + errorID + "\nCorrelation ID: "
           + correlationID + "\nPay Key: " + payKey;
    }


    public void onPaymentCanceled(String paymentStatus) {
        main.resultTitle = "CANCELED";
        main.resultInfo = "The transaction has been cancelled.";
        main.resultExtra = "";
    }

Основной класс:

public class main extends Activity implements OnClickListener {

// The PayPal server to be used - can also be ENV_NONE and ENV_LIVE
private static final int server = PayPal.ENV_LIVE;
// The ID of your application that you received from PayPal
private static final String appID = "APP-0N8000046V443613X";
// This is passed in for the startActivityForResult() android function, the value used is up to you
private static final int request = 1;

public static final String build = "10.12.09.8053";

protected static final int INITIALIZE_SUCCESS = 0;
protected static final int INITIALIZE_FAILURE = 1;
