私はormliteデータベースを使用していますが、アプリケーションの実行中に次のメッセージが表示されることがあります:

この方法では、次の問題が発生します。
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;
}
データベースからオブジェクトの ArrayList を取得しようとすると。
グレー、助けてください。
