在android中使用wcf服务时找不到方法错误？

Question

我正在开发wcf服务。我在Windows手机应用程序中得到了很好的响应。但是安卓人员得到了错误。他们正在获得html response.i.e，（我的wcf调试浏览器页面）。  下面是我的代码：

namespace SampleWcfproject
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "SampleService1" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select SampleService1.svc or SampleService1.svc.cs at the Solution Explorer and start debugging.
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
    [AspNetCompatibilityRequirements(
        RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class SampleService1 : ISampleService1
    {
        public  string getdata(string uuid)
        {
            try
            {


                SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con2"].ConnectionString);
                SqlCommand comm = new SqlCommand("select CircleID, CircleName from Circle", con);
                con.Open();
                comm.ExecuteNonQuery();

                SqlDataAdapter da = new SqlDataAdapter(comm);
                // DataSet ds = new DataSet();
                DataTable dt = new DataTable();
                da.Fill(dt);

                JavaScriptSerializer JSSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
                List<Dictionary<string, object>> DtRows = new List<Dictionary<string, object>>();
                Dictionary<string, object> newrow = null;

                //Code to loop each row in the datatable and add it to the dictionary object
                foreach (DataRow drow in dt.Rows)
                {
                    newrow = new Dictionary<string, object>();
                    foreach (DataColumn col in dt.Columns)
                    {
                        newrow.Add(col.ColumnName.Trim(), drow[col]);
                    }
                    DtRows.Add(newrow);
                }
                con.Close();
                var rowString = JSSerializer.Serialize(DtRows);

                //rowString = rowString.Trim('"');

              rowString =  rowString.Substring(1, rowString.Length - 2);

               return rowString;
            }
            catch (Exception ex)
            {

                List<String> Parameters = new List<String>();
                Parameters.Add("getRechargeCircleList");

             //   SendErrorMail(ex.ToString(), "getRechargeCircleList", Parameters);
               // Context.Response.ContentType = "application/json; charset=utf-8";
               // Context.Response.Write(@" {""Status"":""false"",""Message"" : ""Oops! Something went Wrong""}");
               // return;
            }
            return "false";
        }
