Question

I am working on Mono Android Mobile applicaiton. I am calling my WCF Services in my applicaiton, I added wcf services using ->Add WebRefernce option of Project Menu. My Problem is I am getting exception when i am running the calling the wcf services on the device.

Exception:

{System.Net.WebException: Error: NameResolutionFailure at System.Net.HttpWebRequest.EndGetRequestStream (IAsyncResult asyncResult) [0x00000] in :0

My device has internet connection using WiFi connection to get and post data

I tried calling the services using the net connection using Mobile Data i.e with the Mobile NetWork Provider's internet connection.. This time i am getting a different exception..

{System.Net.WebException: The request failed with HTTP status 404: NotFound at System.Web.Services.Protocols.SoapHttpClientProtocol.ReceiveResponse (System.Net.WebResponse response, System.Web.Services.Protocols.SoapClientMessage message, System.Web.Services.Protocols.SoapExtension[] extensions) [0x00000] in :0 at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke (System.String method_name, System.Object[] parameters) [0x00000] in :0 at AndroidWCFExample.WirelessService.SAGServer.ProcessSomeUpdate (AndroidWCFExample.WirelessService.WebServicesClient oClientInfo, System.String ParameterInfo) [0x00001] in C:\Some Dotnet Examples\AndroidWCFExample\AndroidWCFExample\Web References\WirelessService\Reference.cs:1232 at (wrapper remoting-invoke-with-check) AndroidWCFExample.WirelessService.SAGServer:ProcessSomeUpdate (AndroidWCFExample.WirelessService.WebServicesClient,string) at AndroidWCFExample.EmployeeInfoActivity.button_Click (System.Object sender, System.EventArgs e) [0x0007a] in C:\Some Dotnet Examples\AndroidWCFExample\AndroidWCFExample\EmployeeInfoActivity.cs:79 }
