得到：
javax.net.ssl.SSLPeerUnverifiedException：Web 服务在 Android 中没有对等证书错误。
我分析了关于我的 keyStore 中缺少证书的问题。这个“ https://www.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8 ” Web 服务在我的 salesforce 组织上，但是，我如何从 Salesforce 获取证书，我可以将其添加到我在 android 中的 KeyStore ?
如果有人觉得有帮助，下面是我的目录。
我已经检查了这个链接“ 'No peer certificate' error in Android 2.3 but NOT in 4 ”，但在此之前我需要一个证书在我的原始文件夹中，我如何在没有任何证书的情况下做到这一点。我需要在我的应用程序中使用 Salesforce 客户端证书。
