使用kso​​ap2将Android App连接到ASP .NET Web Service时出错

Question

我正在尝试将我的应用程序连接到我在 ASP 中创建并且当前正在localhost上运行的Web服务。该应用程序正在尝试访问包含3个整数的Coordonate方法。

我提供了代码和 LogCat 。我必须提到我是Web服务的新手。

任何帮助将不胜感激！干杯！

代码：

Answer 1

尝试使用以下行替换localhost和系统的IP地址。

private static final String URL = "http://localhost:49934/Service1.asmx";

这可能会对你有帮助。

即使你在同一个系统上运行的模拟器上测试它，然后asp.net和android都有不同的IP localhost可能10.0.2.2在某些情况下。

Answer 2

之前我遇到过类似的问题。请查看How to call a local .NET web service from an Android Application。

希望有所帮助
