Question

免责声明：我是Android编程的新手:( 我在这里看到了类似的问题，但解决方案对我不起作用。我试图满足正确发布的问题的所有标准，所以请耐心等待。我写了一个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工作正常，所以我知道没有防火墙问题。我的Android浏览器可以毫不费力地点击http://10.0.0.134:4444/DietService.svc?msdl。为匿名用户设置了服务，因此不需要登录信息。我已经检查了所有可能的参考资料，我可以在这里和网上的其他地方找到2天，没有任何帮助。我使用ksoap2 2.5.2并且无法正常工作。我甚至尝试过设置异步任务。我据称已经复制了＃34;工作＆＃34;代码仍然无法获得wcf服务的任何通信。在这一点上，我完全难过了。这是我的堆栈跟踪，代码和传输时的变量：

多少学习经历！在寻找更多答案时，我发现有一个较新的ksoap2库（2.6.0）所以我决定从2.5.2升级。当我这样做时，我注意到我使用的是2.5.2 WITHOUT依赖项。升级后，我的堆栈跟踪更详细，并指示权限错误。快速搜索网络让我检查

 <uses-permission android:name="android.permission.INTERNET"/>

DUH！我忘了将它添加到我的AndroidManifest.xml文件中。答对了！连接已建立。现在我所要处理的只是合同不匹配。这需要将IDietService添加到 SOAP_ACTION 路径：

改变：

final static String SOAP_ACTION = "http://tempuri.org/GetFoodName";

为：

final static String SOAP_ACTION = "http://tempuri.org/IDietService/GetFoodName";

使用ksoap2库的WITH-DEPENDENCIES版本是解决方案的关键。我不知道版本升级是否有帮助。我承认当我的catch块在使用ksoap2 2.5.2时发现e.getMessage（）的null时我很困惑，但是我假设（是的，我知道）那就是它的方式是。底线 -

检查您的详细信息！

ksoap2 ver。 2.5.2无论我尝试
