Mifare Classic カードを読み取ろうとしていますが、認証ステップで失敗します。A と B の両方の認証方法を試しました。

私もこの 質問に精通しており、Mifare Classic カード/タグを読み取ることができない電話のリストへの参照を見つけるこのページも読みました。

私が使用している電話はLG Optimus L5 II E460です。使ったことある方いますか？

電話がMifare Classicカード/タグを読み取れるかどうか、アプリケーション内で確認する方法はありますか?

MifareClassic.KEY_DEFAULT ではなく個人キーで Mifare Classic カード/タグをロックする方法はありますか?

Mifare Classic カード/タグをフォーマットする方法はありますか? フォーマットとは、 Factory Resetのように、カード/タグからすべてを消去することを意味します。

これが私のコードです：

public class NFC_Writer extends AppCompatActivity {

private NfcAdapter mNfcAdapter;
private Tag mTag;

@Override

    super.onCreate(savedInstanceState);

Ndef を使用するためにNdefFormatableを使用してカードをフォーマットしようとしましたが、 NdefFormatable ::connect()関数を呼び出すとIOExceptionがスローされます。

MifareClassicクラスを使用しようとすると、関数authenticateSectorWithKeyBまたはauthenticateSectorWithKeyAを呼び出すと、常にfalseを受け取ります。

Tag ::getTechList()を呼び出すと、次のリストを受け取るため、この両方の方法を試しました。

すべてのログは次のとおりです。

私が行ったすべての調査の後、互換性の問題があると結論付けました。

これは、NTAG21Xチップを搭載したNTAG216カードの読み取り/書き込みに成功し、私の知る限り、MIFARE S50チップを搭載したABK-1001MFカードの代替品として登場したためです。これは、私が最初に読み取り/書き込みを試みたカードです。 、同じタイプの電話LG Optimus L5 II E460を使用しています。

私の結論は、私が呼び出すときに次の事実によって強化されます。

getPackageManager().hasSystemFeature("com.nxp.mifare");

戻り値は false です。

助けてくれてありがとう！
