我正在使用 KSOAP2 调用异步 Web 服务（服务器不返回任何内容）。Web 服务调用已经成功，我可以从服务器上看到，但是 HttpTransportSE.call 抛出异常并导致应用程序崩溃。

我的代码是：

envelope.bodyOut = soap;
    envelope.dotNet = false;
    MarshalDouble md = new MarshalDouble();
    md.register(envelope);


        HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
        androidHttpTransport.debug = true;
        try {
            androidHttpTransport.call(null, envelope);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        }

错误日志是：

有人知道为什么吗？如何使用 ksoap 调用异步 Web 服务？谢谢。

我检查了 HttpTransportSE.java 的代码，似乎没有办法阻止它获得响应。所以我必须将我的 web 服务更改为同步并返回类似 OK 的内容来解决这个问题。希望 KSOAP2 能解决这个问题。
