Connecting to web service ends with SocketTimeoutException

Question

I have code segment that connects to a web service. My app has a button, when pressed fetches some data from server and shows to user. It is very simple, but never works. I have read all of post regards to my problem, but none of them solved it. The code is used from codeproject sample:

public void onClick(View v) {
    SoapObject request = new SoapObject("http://tempuri.org/", "Add");
    PropertyInfo pi=new PropertyInfo();
    pi.setName("a");
    pi.setValue(10);
    pi.setType(Integer.class);
    request.addProperty(pi);
    pi=new PropertyInfo();
    pi.setName("b");
    pi.setValue(15);
    pi.setType(Integer.class);
    request.addProperty(pi);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    envelope.dotNet = true;

    envelope.setOutputSoapObject(request);

    HttpTransportSE httpTransport = new HttpTransportSE("http://grasshoppernetwork.com/NewFile.asmx");
    String response="";
    try
    {
        httpTransport.call("http://tempuri.org/Add", envelope);
        response = (envelope.getResponse()).toString();
    }
    catch (Exception exception)
    {
        response=exception.toString();
    }


    onSoapRequestFinished(response.toString());
}

I have added 2 permissions: Network_Access and Internet. Surprisingly, the web service is accessible from AVD's browser.

The errors are:

Answer 1

I post the answer for future readers. After investigating many methods i found that the imported library for KSoap was wrong. I used ksoap.jar for my app which couldn't connect to server. I replaced it with ksoap2-android-assembly-2.6.0-jar-with-dependencies and anything goes well as expected.

Additionally, volley library works as charm.
