免责声明：我是 Android 编程的新手 :( 我在这里看到过类似的问题，但该解决方案对我不起作用。我正在努力满足正确发布问题的所有标准，所以请多多包涵。我写道一个 C# 客户端来测试我的 wcf 服务（SimpleHTTPTransport），它可以在第二台计算机上通过 WiFi 正常工作，所以我知道没有防火墙问题。我的 Android 浏览器可以访问 http://10.0.0.134:4444/DietService.svc?msdl没有问题。该服务是为匿名用户设置的，因此不需要登录信息。在没有帮助的情况下，我已经检查了我在这里和网络上其他地方可以找到的所有可能的参考资料 2 天。我正在使用 ksoap2 2.5.2 并且无法正常工作。我什至尝试过设置异步任务。我复制了所谓的“工作”代码，但仍然无法与 wcf 服务通信。在这一点上，我完全被难住了。这是我的堆栈跟踪、代码和传输时的变量：
