模擬器 - 互聯網連接問題

Question

我已經在模擬器中設置了我的代理設置，我可以在模擬器的瀏覽器上訪問普通的互聯網。但是當我嘗試運行我的應用程序時，它會給出錯誤 但是，當我將URL更改爲在組織內運行的服務時，我可以獲取數據！

這裏有什麼問題，如何通過我的應用程序連接到我的組織之外的URL？

這裏是我的代碼：

  StringBuffer b = new StringBuffer(); 
     System.out.println("try"); 
     String registrationUrl = "http://google.com"; 
     url = new URL(registrationUrl); 
     System.out.println("url"); 
     URLConnection connection = url.openConnection(); 
     System.out.println("open connection"); 
     conn = (HttpURLConnection) connection;   
     int responseCode = conn.getResponseCode(); 
     System.out.println(responseCode); 
     is = conn.getInputStream(); 
     long len = 0; 
     int ch = 0; 
     len = conn.getContentLength(); 
     if (len != -1) { 
      // Read exactly Content-Length bytes 
      System.out.println("IF..."); 
      for (int i = 0; i < len; i++) { 
       System.out.println("For Loop..."); 
       if ((ch = is.read()) != -1) { 
        System.out.println("Appending"); 
        b.append((char) ch); 
       } 
      } 
     } else { 
      // Read till the connection is closed. 
      System.out.println("Else..."); 
      while ((ch = is.read()) != -1) { 
       System.out.println("When..."); 
       len = is.available(); 
       System.out.println("append"); 
       b.append((char) ch); 
      } 
     } 


     String data = b.toString(); 
     AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setMessage(data).setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int id) { 
       xml_test.this.getParent(); 
      } 
     });

我沒有太多的時間去通過什麼實際需要，但如果你想申請代理到您的應用程序檢查以下示例..
