android soap webservers 无法执行 报错 ht.call(SOAP_ACTION, envelope);解决方法

1.可能没有加入网络访问权限，在Manifest里面加入，<uses-permission android:name="android.permission.INTERNET"/>

2.版本问题，很可能的问题，因为在android高于9的会出错，所以简单粗暴的办法就是，直接将版本信息

<uses-sdk
android:minSdkVersion="？"
android:targetSdkVersion="?"

/>

删除即可。

其他具体参考代码如下：
