Android RuntimeException Gson解析异常：无法调用受保护的java.lang.ClassLoader（）

Question

我正在尝试传递ArrayList of Intent中的SharedPreferences个对象。为此，我使用gson将ArrayList of Intents转换为String，然后设置共享首选项。设置共享首选项已成功完成，但在检索时，我收到以下异常：

设置SharedPreferences

ArrayList<Intent> notificationIntent = new ArrayList<Intent>();

SharedPreferences.Editor editor = prefs.edit();
String connectionsJSONString = new Gson().toJson(notificationIntent);
editor.putString("intents", connectionsJSONString);
editor.commit();

从SharedPreference

重播

String connectionsJSONString = PreferenceManager.getDefaultSharedPreferences(this)
                                        .getString("intents", null);
Type type = new TypeToken < ArrayList < Intent >> () {}.getType();
notificationsIntent = new Gson().fromJson(connectionsJSONString, type);

任何人都可以帮助我，我怎样才能实现这种行为？

提前致谢

我解决此问题的方法是使用必要的数据创建自己的对象。它节省了空间并修复了这个问题。当您尝试序列化android对象时会出现此问题。
