我正在尝试处理PayPal预付款付款。
我使用以下代码，可在PayPal集成指南中找到：
RequestEnvelope requestEnvelope = new RequestEnvelope("en_US");
PreapprovalRequest preapprovalRequest = new PreapprovalRequest();
preapprovalRequest.setRequestEnvelope(requestEnvelope);
preapprovalRequest.setCurrencyCode("USD");
preapprovalRequest.setStartingDate("2014-03-22");
preapprovalRequest.setEndingDate("2015-03-22");
preapprovalRequest.setMaxAmountPerPayment(1.0);
preapprovalRequest.setMaxNumberOfPayments(5);
preapprovalRequest.setMaxTotalAmountOfAllPayments(5.0);
preapprovalRequest.setSenderEmail("platfo_1255077030_biz@gmail.com");
preapprovalRequest.setCancelUrl("https://devtools- paypal.com/guide/ap_preapprove_payment?cancel=true");
preapprovalRequest.setReturnUrl("https://devtools- paypal.com/guide/ap_preapprove_payment?success=true");
preapprovalRequest.setIpnNotificationUrl("http://replaceIpnUrl.com");
Map<String, String> sdkConfig = new HashMap<String, String>();
sdkConfig.put("mode", "sandbox");
sdkConfig.put("acct1.UserName", "jb-us-seller_api1.paypal.com");
sdkConfig.put("acct1.Password", "WX4WTU3S8MY44S7F");
sdkConfig.put("acct1.Signature","AFcWxV21C7fd0v3bYYYRCpSSRl31A7yDhhsPUU2XhtMoZXsWHFxu-RWy");
sdkConfig.put("acct1.AppId","APP-80W284485P519543T");
AdaptivePaymentsService adaptivePaymentsService = new AdaptivePaymentsService(sdkConfig);
PreapprovalResponse preapprovalResponse = adaptivePaymentsService.preapproval(preapprovalRequest);
但是我收到了这个错误：

看起来您正在尝试在Android上使用PayPal Java SDK。不幸的是，SDK从未设计用于Android，并且因为依赖于Sun SDK而失败。请参阅a similar issue here。
