我正在从我的 android 应用程序调用 ksoap Web 服务，但它会引发异常：请参阅下面是我的代码：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
}
try {
makingEnvelopAndReady(URL, METHOD_NAME, 10, 10,
"Daily", 5000, 10, "Hourly");
} catch (Exception e) {
// TODO: handle exception
Log.v("Excepotuion in main method : ",
"Excepotuion in main method : " + e);
}
}

这是数据信息：
private final String URL = "http://brainteclabs.com:8180/MobileContractorCalculationService.svc";
private final String SOAP_ACTION = "http://tempuri.org/IMobileContractorCalculationService/Calculate";
private final String METHOD_NAME = "Calculate";
我已经很努力了，使用了很多方法来请求 ksoap Web 服务，但仍然没有得到任何成功的结果，请查看我的代码并告诉我我在哪里遗漏了一些东西。
