  關於記憶體溢出的問題，此間一個網路請求，返回json資料

HttpURLConnection connection = (HttpURLConnection) httpUrl        .openConnection();//設定參數  請求為get請求connection.setReadTimeout(5000);connection.setRequestMethod("GET");//connection.getInputStream()得到位元組輸入資料流，InputStreamReader從位元組到字元的橋樑，外加封裝字元流BufferedReader bufferedReader = new BufferedReader(        new InputStreamReader(connection.getInputStream()));//建立字串容器StringBuffer sb = new StringBuffer();String str = "";//行讀取while ((str = bufferedReader.readLine()) != null) {    // 當讀取完畢，就添加到容器中    sb.append(str);}//測試是否得到json字串Log.e("TAG", "" + sb.toString());

此json字串過大，導致buffer,申請記憶體失敗，

其實你可以添加在你的清單
