Question

在我的应用中使用android keystore时，我遇到一个奇怪的问题。

仅在 Mi设备上发生（与Mi A1和Redmi Note 4型号一起尝试过）。

这是我生成要存储在androidkeystore中的密钥的方式：

final SecretKey secretKey;
        final KeyGenerator keyGenerator = KeyGenerator.getInstance(KeyProperties.KEY_ALGORITHM_AES, "AndroidKeyStore");
        final KeyGenParameterSpec keyGenParameterSpec = new KeyGenParameterSpec.Builder("alias",
            KeyProperties.PURPOSE_ENCRYPT | KeyProperties.PURPOSE_DECRYPT)
            .setBlockModes(KeyProperties.BLOCK_MODE_CBC)
            .setUserAuthenticationRequired(true)
            .setUserAuthenticationValidityDurationSeconds(5)
            .setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_PKCS7)
            .setRandomizedEncryptionRequired(false)
            .build();
        keyGenerator.init(keyGenParameterSpec);
        secretKey = keyGenerator.generateKey();

现在在使用时，如果我在1秒钟的间隔后多次重复使用该键，

间歇地看到以下运行时异常：

android.security.KeyStoreException: Invalid user authentication validity duration
        at android.security.KeyStore.getKeyStoreException(KeyStore.java:692)
        at android.security.KeyStore.getInvalidKeyException(KeyStore.java:777)

        at javax.crypto.Cipher.init(Cipher.java:973) 
        at javax.crypto.Cipher.init(Cipher.java:908)

IMO，这似乎是Mi提供程序的错误。

任何帮助/解决方法将不胜感激。
