API 10以降ではURLConnectionは機能しませんか？

ねえ、私はアンドロイドアプリで大きな問題を抱えています。それはBufferedReaderの@クラッシュ...API 10以降ではURLConnectionは機能しませんか？

URL url = new URL(PingUrl); 
URLConnection Conn = url.openConnection(); 
Conn.setConnectTimeout(4000); 
int Size = 2048; 
BufferedReader input = new BufferedReader(new InputStreamReader(Conn.getInputStream()), Size); 
String line = null; 
while ((line = input.readLine()) != null) { 
    JSONObject jo = new JSONObject(line); 
    String timeStamp = jo.getString("timestamp"); 
    //Log.i("Value",timeStamp); 
} 
input.close(); 
result = true;

を私は現在、それを更新していると私は、API 10にAPI 8から切り替えて次のコードブロックはもう動作しません...誰もがアイデアを得ましたか？
