如何在android 11中检测指纹硬件

<uses-permission android:name="android.permission.USE_FINGERPRINT" />

if (ContextCompat.checkSelfPermission(this, Manifest.permission.USE_FINGERPRINT) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.USE_FINGERPRINT}, REQUEST_FINGERPRINT_PERMISSION);
}

private FingerprintManager.AuthenticationCallback authenticationCallback = new FingerprintManager.AuthenticationCallback() {
    @Override
    public void onAuthenticationSucceeded(FingerprintManager.AuthenticationResult result) {
        // 指纹识别成功
    }

    @Override
    public void onAuthenticationFailed() {
        // 指纹识别失败
    }

    @Override
    public void onAuthenticationError(int errorCode, CharSequence errString) {
        // 指纹识别错误
    }
};

FingerprintManager fingerprintManager = getSystemService(FingerprintManager.class);
fingerprintManager.authenticate(null, null, 0, authenticationCallback, null);
