odata，Noclass創建人錯誤

下面是Android嘗試使用odata檢索數據的代碼。 OdataWebNorthwindModelService是代理類的名稱（自動生成）...我跟着http://weblogs.asp.net/uruit/archive/2011/09/13/accessing-odata-from-android-using-restlet.aspx尋求幫助...但我有一些問題..請幫助我。odata，Noclass創建人錯誤

package com.example.odatajsondatagrabbing; 


import northwindmodel.Category; 

import org.restlet.ext.odata.Query; 

import OdataWebNorthPackage.OdataWebNorthwindModelService; 
import android.app.Activity; 
import android.os.Bundle; 


public class MainActivity extends Activity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     OdataWebNorthwindModelService service = new OdataWebNorthwindModelService(); 

     Query<Category> query = service.createCategoryQuery("/Categories"); 

     for(Category cate: query){ 
      System.out.println("ID::"+cate.getCategoryId()); 
      System.out.println("Name::"+cate.getCategoryName()); 
      System.out.println("\n"); 
     } 
    } 
}

下面是我上運行的應用程序

錯誤是從構造來當我試圖debugging..below得到的錯誤是自動生成的代碼

package OdataWebNorthPackage; 

import northwindmodel.*; 
import org.restlet.ext.odata.Query; 
public class OdataWebNorthwindModelService extends org.restlet.ext.odata.Service { 

    public OdataWebNorthwindModelService() { 
     super("http://services.odata.org/Northwind/Northwind.svc"); 
    } 

    public void addEntity(Category entity) throws Exception { 
     addEntity("/Categories", entity); 
    } 

    public Query<Category> createCategoryQuery(String subpath) { 
     return createQuery(subpath, Category.class); 
    } 

    public void addEntity(CustomerDemographic entity) throws Exception { 
     addEntity("/CustomerDemographics", entity); 
    } 

    public Query<CustomerDemographic> createCustomerDemographicQuery(String subpath) { 
     return createQuery(subpath, CustomerDemographic.class); 
    } 
}

你做完了嗎？

項目>屬性> Java構建路徑>訂單和導出>最後，勾選導入的OData4j庫。

此外，不要在UI線程上使用web服務，請考慮服務或AsyncTask
