我使用ormlite数据库，有时在应用程序运行时，我会收到：

此方法导致此问题：
public ArrayList<ReminderItem> getDisplayReminders(Context context)
{
ArrayList<ReminderItem> contactsList = null;
DatabaseHandler db = new DatabaseHandler(getContext().getApplicationContext());
try {
db.getWritableDatabase();
Dao<ReminderItem,Integer> daoSubject = db.getReminderDao();
contactsList = (ArrayList<ReminderItem>) daoSubject.queryForAll();
}
catch(Exception e)
{
e.printStackTrace();
}
return contactsList;
}
当我尝试从数据库中获取对象的ArrayList时。
格雷，请帮忙。
