post to wcf using volley (android) - android-volley

Question

i am trying to solve this error from a week but any of my workaround is not working unfortunately
i am trying to send json String like this String={"name":"ABC"} to WCF(ASP.NET) using volley library post method but its not working anyhow gives this error
BasicNetwork.performRequest: Unexpected response code 400 for http://192.168.1.11/MyDemoService/Service1.svc/insert
i am not sure what is wrong and where is the mistake is being made
Here is the WCF Code:
[WebInvoke(Method = "POST", UriTemplate = "insert", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
string insert(string name);
insert Function :
public string insert(string name)
{
//write database related insert logic here.
//string response2="{\"name\":\"mohib\"}";
//info m = JsonConvert.DeserializeObject<info>(name);
//string n = m.name;
// string ds = name;
string conStr = #"Data Source=CRESIDIAN-DELL;Initial Catalog=WCFTest;User Id=sa;Password=1234";
// string msg = "true";
try
{
SqlConnection con = new SqlConnection(conStr);
con.Open();
string query = "insert into DemoTable (name) values ('" + name + "')";
SqlCommand com = new SqlCommand(query, con);
com.ExecuteNonQuery();
msg = "Inserted";
con.Close();
}
catch (Exception e)
{
e.ToString();
}
return msg;
}
