Question

我在使用ksoap通过android调用web服务时遇到问题。如果minSdkVersion =“11”，那么我得到一个例外，你可以在下面看到。但如果我将minSdkVersion属性的值设置为9或更低，那么我可以调用webservice 。 ksoap和minsdkversion有什么关系？请帮帮我，我该怎么办？

ps：现在我将开发一个应用程序，它将在平板电脑（蜂窝）上运行。我的目标api级别已设置为11.

编辑：我正在使用ksoap2-android-assembly-2.4-jar-with-dependencies

您正在主用户界面线程上调用网络操作（通过ksoap进行Web服务）。在api级别11下，不再允许/可能。在任何情况下，这都是非常糟糕的做法，因为它在网络操作进行时挂起了UI。

使用AsyncTask并在那里调用webservice。顺便说一句。这与ksoap完全无关......任何网络操作都会遇到这个问题。

另外你应该升级到我最近发布的最新版本的ksoap2-android。 2.4.0很老了，有很多问题。

Android上的ksoap和minSdkVersion =“11”
