***This is my main class***

```

This is my main activity code, it's not running and is giving errors!
I am trying to call a `webserive` that I made in `Asp.net`, But it is giving errors the `webservice` is working fine on website, should I first install a `webserivce` on a website and then integrate it with the android app? Please help me out as I am an amatuer developer, trying to fight my way through this learning phase. thank you.
