与HttpWebRequest / HttpClient的Android问题

Question

I have asp.net web service. The web service has url like this:
mydomain dot com/service.asmx/getlocation?id=100

I always get below error. I tried both synchronous and async ways. I even tried to use Google.com but I always get below error:

Unhandled Exception:

 System.Net.WebException: The remote server returned an error: (500) Internal Server Error. 

My code looks like this:

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(url));
request.ContentType = "application/json";
request.Timeout = 60000;
request.Method = "GET";

// I get error here 
using (WebResponse response =  request.GetResponse())
{
    // Get a stream representation of the HTTP web response:
    using (Stream stream = response.GetResponseStream())
    {
        // Use this stream to build a JSON document object:
        JsonValue jsonDoc = await Task.Run(() => JsonObject.Load(stream));
        Console.Out.WriteLine("Response: {0}", jsonDoc.ToString());

        // Return the JSON document:
        return jsonDoc;
    }
}

Thanks

Edit :

I tried it on different emulators- Nexus 7 Lollipop(5.1.0) and Nexus S(4.4.2)

It seems that returning JSON from a SOAP Service is quite tricky, I have looked at this stackoverflow question .
