OutOfMemoryError в AbstractStringBuilder enlargeBuffer

Я читаю ответ youtube в Stream и преобразовываю его в String. используя приведенный ниже код:

URL: http://gdata.youtube.com/feeds/api/users/cnn/uploads?&v=2&max-results=25&alt=json

private String convertStreamToString(InputStream is) {

        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();

        String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }        
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return sb.toString();
    }

Этот код отлично работает на всех устройствах, кроме устройств Android 4.0. Я получаю ниже logcat:
