我運行的代碼，這是一個：

public class sdf { 

static String url = "http://www.google.es"; 

public static void main(String[] args) { 

    try { 
     BufferedReader br = new BufferedReader(new InputStreamReader(
       new DefaultHttpClient().execute(new HttpGet(url)) 
         .getEntity().getContent())); 
     String line; 
     while ((line = br.readLine()) != null) { 
      System.out.println(line); 
     } 

    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
} 
}

不要緊，什麼是網址的價值，也不會工作。

我在做什麼錯？

您是否擁有擁有正確權限的清單？這是一個例子，你需要做的：

<manifest xlmns:android...> 
... 
     <uses-permission android:name="android.permission.INTERNET"></uses-permission> 
</manifest>

沒有這一點，你將不能夠有互聯網連接

是的，我做到了。該應用程序確實連接到互聯網。 – razielsarafan

我不明白。如果上面的代碼不適用於任何URL，那麼您的應用程序的哪部分「連接到互聯網」？ –
