在Android手机的REST服务中找不到端点

好的，我有一个WCF服务，让我给一个端点没有发现错误，我看不出它为什么…这是我的代码。

首先，接口:

 public interface ISightingServiceRest
 {
    [OperationContract]
    [WebInvoke(Method = "POST", 
    UriTemplate = "SaveNewSightingRest", 
    ResponseFormat = WebMessageFormat.Json, 
    RequestFormat = WebMessageFormat.Json)]
    string SaveNewSightingRest(string sighting);
 }

现在，实际方法:

public string SaveNewSightingRest(string sighting)
{
    string received = sighting;
    return "hola";
}

当我调试时，我想要的只是在我的响应中看到字符串"hola"，在变量"received"中看到发送的字符串。

现在，webconfig:

    <?xml version="1.0"?>

  <connectionStrings>
    <add name="LiveAndesWCF" connectionString="Data Source=BRUNO-PC'LIVEANDES;

  </system.webServer>
</configuration>

最后，我使用的方法从模拟器:

private void addNewSighting() throws Exception
{
    String URL = "http://10.0.2.2:61642/SightingServiceRest.svc";
    AlertDialog popup;
    SightingWrapper sighting = new SightingWrapper();
    String xml = createXML(sighting);
    try{
        HttpPost request = new HttpPost(URL + "/SaveNewSightingRest/");
        StringEntity sen = new StringEntity(xml);
        request.setHeader("Accept", "application/json");
        request.setHeader("Content-type", "application/json; charset=utf-8");
        request.setEntity(sen);
        DefaultHttpClient httpclient = new DefaultHttpClient();
        HttpResponse response = httpclient.execute(request);
        HttpEntity responseEntity = response.getEntity();
        char[] buffer = new char[(int)responseEntity.getContentLength()];
        InputStream stream = responseEntity.getContent();
        InputStreamReader reader = new InputStreamReader(stream);
        reader.read(buffer);
        stream.close();
        String responseString = new String(buffer);
    }
    catch(Exception e)
    {           
    }
}

我在"responseString"中收到"Endpoint not found"消息。

我不知道我的错误在哪里。

任何帮助都是感激的。

谢谢

HttpPost request = new HttpPost(URL + "/SaveNewSightingRest/"); //before
HttpPost request = new HttpPost(URL + "/SaveNewSightingRest"); //after
