如何在paypal中报告应用android的描述？

我正在用android做一个应用程序。我使用PayPalPayment.class与paypal连接，我想报告更多详细信息中显示的她的销售描述

我的部分代码：

PayPalPayment thingToBuy = new PayPalPayment(new BigDecimal("4.99"), "EUR", "Datos de contacto - "+pro.getTitulo());

Intent intent = new Intent(InfoProyecto.this, PaymentActivity.class);

intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, CONFIG_ENVIRONMENT);
intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, CONFIG_CLIENT_ID);
intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, CONFIG_RECEIVER_EMAIL);
// It's important to repeat the clientId here so that the SDK has it if Android restarts your 
// app midway through the payment UI flow.
intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, "APP-80W284485P519543T");
intent.putExtra(PaymentActivity.EXTRA_PAYER_ID, "your-customer-id-in-your-system");
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);

startActivityForResult(intent, 0);

这样试试

Intent intent = new Intent(this, PayPalService.class);        
intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, CONFIG_ENVIRONMENT);
intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, CONFIG_CLIENT_ID);
intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, CONFIG_RECEIVER_EMAIL);        
startService(intent);

外部

onCreate（）

交易ID

（支付ID）

public void onBuyPressed(View pressed) {
    Double amount=Double.parseDouble(Amount.toString());

    PayPalPayment thingToBuy = new PayPalPayment(new BigDecimal(String.valueOf(amount)), "NOK","ITEM_S");        
    Intent intent = new Intent(this, PaymentActivity.class);        
    intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, CONFIG_ENVIRONMENT);
    intent.putExtra(PaymentActivity.EXTRA_CLIENT_ID, CONFIG_CLIENT_ID);
    intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, CONFIG_RECEIVER_EMAIL);
    intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);

    startActivityForResult(intent, 0);
}
