Ошибка аутентификации Android Mifare Classic

Есть ли способ проверить внутри моего приложения, может ли телефон считывать карты/метки Mifare Classic?

Есть ли способ заблокировать карту/метку Mifare Classic с помощью личного ключа, а не MifareClassic.KEY_DEFAULT?

Есть ли способ отформатировать карту/метку Mifare Classic? Под форматом я подразумеваю удаление всего с карты/метки, например Восстановление заводских настроек.

Вот мой код:

}

@Override

Я пытался использовать NdefFormatable для форматирования карты, чтобы работать с Ndef, но IOException возникает, когда я вызываю Функция NdefFormatable::connect().

Когда я пытаюсь использовать класс MifareClassic, я всегда получаю false при вызове функции authenticateSectorWithKeyB или authenticateSectorWithKeyA.

Я пробовал оба этих метода, потому что при вызове Tag::getTechList() я получаю следующий список: android.nfc.tech.NfcA, android. nfc.tech.MifareClassic, android.nfc.tech.NdefFormatable;
