Android Paypal多项目开放类

我想为应用程序中的2项服务向用户收费，但我对Paypal Android SDK非常不熟悉。这是我到目前为止所拥有的

 public void onClick(View v) {

            PayPalPayment payment2 = new PayPalPayment(new BigDecimal("0.79"), "USD", "Network Fee");

            Intent intent = new Intent(getBaseContext(), PaymentActivity.class);

            // comment this line out for live or set to PaymentActivity.ENVIRONMENT_SANDBOX for sandbox
            intent.putExtra(PaymentActivity.EXTRA_PAYPAL_ENVIRONMENT, PaymentActivity.ENVIRONMENT_NO_NETWORK);

            // 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, "credential-from-developer.paypal.com");

            // Provide a payerId that uniquely identifies a user within the scope of your system,
            // such as an email address or user ID.
            intent.putExtra(PaymentActivity.EXTRA_PAYER_ID, "<xxxxxxxxxx.co.uk>");

            intent.putExtra(PaymentActivity.EXTRA_RECEIVER_EMAIL, "<xxxxxxxxxx.com>");

            intent.putExtra(PaymentActivity.EXTRA_PAYMENT, payment2);


           startActivityForResult(intent, 0);

        }

我尝试过创建多个意向和PaypalPayment类，但都没有效果。如果这太复杂而无法解释，请将我链接到教程系列

ps：我想在两个服务提供商之间分配付款

谢谢

目前，SDK只支持一种简单的支付方式。我建议让用户一次性支付全部金额

期待未来的改进，以便在2014年初获得详细的结果
