我正在尝试使用 Android 附带的 HTTPClient 4 实现将 Android 应用程序与托管在 Google App Engine for Java (https://applicationname.appspot.com) 中的安全 HTTPS 远程服务连接起来。该证书已签名且有效形式为 *.appspot.com。
我在真实设备（HTC Hero）中使用 Android 2.1，我收到以下错误：SSL23_GET_SERVER_HELLO:unknown protocol.
这是我的代码的一部分：
HttpParams params = new BasicHttpParams();
...
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(
new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schemeRegistry.register(
new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
..
ClientConnectionManager cm =
new ThreadSafeClientConnManager(params, schemeRegistry);
DefaultHttpClient result = new DefaultHttpClient(cm, params);
关于可能发生的事情以及任何解决方案或解决方法的任何想法？
这是完整的堆栈跟踪：
