Android NFC读和写踩坑版

环境  android studio 2022   sdk 33

 刚刚开始我的代码是这样的，结果给我的 提示 接收到的Intent不是由NFC触发的  我很蒙圈为什么然后我见过我调试 我发现 我改 里面的那个 

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "NfcWriteActivity";
    private NfcAdapter nfcAdapter;
    private TextView mTvName;
    public static IntentFilter[] mIntentFilter = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mTvName = findViewById(R.id.textView);
        nfcAdapter = NfcAdapter.getDefaultAdapter(this);
        if (nfcAdapter == null) {
            Toast.makeText(this, "不支持NFC功能", Toast.LENGTH_SHORT).show();
            return;
        }

        if (!nfcAdapter.isEnabled()) {
            Toast.makeText(this, "请打开NFC功能", Toast.LENGTH_SHORT).show();
            Intent inten = new Intent(Settings.ACTION_NFC_SETTINGS);
            // 根据包名打开对应的设置界面
            startActivity(inten);
            return;
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        try {
            IntentFilter filter = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
            IntentFilter filter3 = new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);
            IntentFilter filter2 = new IntentFilter(NfcAdapter.ACTION_TAG_DISCOVERED);
            String[][] techList = new String[][]{new String[]{NfcA.class.getName()}, {Ndef.class.getName()}, {MifareUltralight.class.getName()}};
            mIntentFilter = new IntentFilter[]{filter, filter2, filter3};
            PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 10, new Intent(this, this.getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE);
            nfcAdapter.enableForegroundDispatch(this, pendingIntent, mIntentFilter, techList);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        try {
            nfcAdapter.disableForegroundDispatch(MainActivity.this);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }


    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        setIntent(intent);

        String action = intent.getAction();

            Log.e(TAG, "");
            Toast.makeText(this, "接收到的Intent不是由NFC触发的", Toast.LENGTH_SHORT).show();
            return;
        }

        if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(intent.getAction())) {
            Parcelable[] rawMessages =
                    intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
            if (rawMessages != null) {
                NdefMessage[] messages = new NdefMessage[rawMessages.length];
                for (int i = 0; i < rawMessages.length; i++) {
