I have created an android application using (Jquery & PhoneGap). The application works fine Now, I want to retrieve data from my ASP.NET Web Service.

html:

<html>
<head>
    <meta charset="utf-8">
    <title>My Friends</title>

    <link href="Jquery-mobile/jquery.mobile-1.1.0.css" rel="stylesheet" type="text/css" />
    <script src="Jquery-mobile/jquery-1.4.1.js" type="text/javascript"></script>

    <script src="Jquery-mobile/jquery.mobile-1.1.0.js" type="text/javascript"></script>
     <script type="text/javascript">


        $(function(){
             //code to fetch data from webservice  

             alert($("#test").html());
        });
    </script>

  </head>
  <body>
</body>
</html>

asp.net web service

/// <summary>
    /// Summary description for WebService1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }
    }

    First uncomment the following line in the service

        .....
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

    [System.Web.Script.Services.ScriptService] 
    // uncomment this ^ ^
    public class WebService1 : System.Web.Services.WebService
    {
    .....

    To call the hello world method use jQuery.ajax

    $.ajax({
  type: "POST",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  url: "WebService1.asmx/HelloWorld",
  data: "{}",
  success: function(msg){
      $("body").append(msg.d); //will append "Hello world" to body tag
  },
  error: function () {

  }
});

    I would recommend you to us WCF REST services instead
