解决方案

当您试图从你的主线程通过HTTP传达错误。

刚刚宣布的请求对象之前添加这些2号线:

  StrictMode.ThreadPolicy政策=新StrictMode.ThreadPolicy.Builder()permitAll()建立()。
StrictMode.setThreadPolicy(政策);

I am trying to send the login credentials from android user to a C# web service running in my local host through visual studio. I have used KSOAP2 for the SOAP communication and wanted to send the login info to the web service and print it in the UI. I have used Asynctask but I have been getting the below error posted here.

解决方案

That error is when you try to communicate through http from your main thread.

Just add those 2 lines before declaring the 'request' object:

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
