我是创建一个WCF Web服务，我想在Android客户端中使用它我有一个问题，我找不到它 . 如果我把这个链接的其他链接：http://jsonparsing.parseapp.com/jsonData/moviesDemoItem.txt我的客户工作 .

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {

        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json,
                                   BodyStyle = WebMessageBodyStyle.Bare,
                                   UriTemplate = "GetData.txt")]
        string GetData();

        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json,
                                  BodyStyle = WebMessageBodyStyle.Wrapped,
                                  UriTemplate = "GetDataUsingDataContract/")]
        List GetDataUsingDataContract();

        // TODO: Add your service operations here
    }


    // Use a data contract as illustrated in the sample below to add composite types to service operations.
    [DataContract]
    public class CompositeType
    {
        bool boolValue = true;
        string stringValue = "Hello ";

        [DataMember]
        public bool BoolValue
        {
            get { return boolValue; }
            set { boolValue = value; }
        }

        [DataMember]
        public string StringValue
        {
            get { return stringValue; }
            set { stringValue = value; }
        }
    }
}
