我想知道 Android应用中的哪个位置可以放置支付Paypal付款状态的代码？它在我的Android应用程序中的support activity.java文件中吗？我所说的代码是：
curl https://api.sandbox.paypal.com/v1/payments/payment/PAY-5YK922393D847794YKER7MUI \ -H "Content-Type: application/json" \ -H "Authorization: Bearer {accessToken}"
我已阅读API文档，但我找不到在何处或如何实施验证过程
感谢您的任何建议

PayPal已经有SDK解释如何实施其服务，请查看完整实施的付款和验证活动。 source
的链接您必须使用控制台的相应配置PayPalConfiguration变量。
onActivityResult拥有您需要的所有付款验证。
注意：您可以使用SandBox进行测试，只需从控制台获取SandBox客户端ID并将其添加到常量CONFIG_CLIENT_ID。
请看下面的完整实施：

您不应该在Android应用中使用付款付款状态API。
相反，SDK将足以返回通过App进行的付款状态。您需要使用开发人员文档中提到的Paypal Android SDK - Paypal Mobile SDK。
SDK将处理完成交易所需的所有调用。您只需提供启动事务所需的PayPalConfiguration属性。事务完成后，OnActivityResult将具有事务，状态代码等状态，您可以根据该状态确定事务状态。
如果您确实必须使用Paypal支付状态api，那么您应该在服务器上使用它作为已在paypal完成的交易的备份但是您的服务器或您的应用程序未收到回复。
为此 - 设置一个cron并为这些类型的交易指定特定状态，例如待处理付款。在cron中，您可以获得所有订单的响应，并根据完成状态处理它们。
