Call Web Service in Android application

Question

I want to call .net web service into Android application. For that I am using running web service available on net called "www.w3schools.com/webservices/tempconvert.asmx"

It's running successfully with browser, but when I call it in my Android application it gives me error in my tab device. The log cat info is shown below:
