Android VerifyError 异常

Question

我在我的应用程序中使用指纹传感器。我知道 api 可用于 marshmallow 及以上操作系统。因此，在我的类里面运行时，我正在动态检查 sdk 版本。

即使指纹代码不执行，我在 4.0 android 操作系统上也面临以下异常，而同样的代码在 5.0 及更高版本上执行。

我发现，由于我在类里面遵循了以下代码，所以我遇到了这个问题。

public boolean cipherInit() {
    try {
        cipher = Cipher.getInstance(KeyProperties.KEY_ALGORITHM_AES + "/" + KeyProperties.BLOCK_MODE_CBC + "/" + KeyProperties.ENCRYPTION_PADDING_PKCS7);
    } catch (NoSuchAlgorithmException | NoSuchPaddingException e) {
        throw new RuntimeException("Failed to get Cipher", e);
    }

    try {
        keyStore.load(null);
        SecretKey key = (SecretKey) keyStore.getKey(KEY_NAME,
                null);
        cipher.init(Cipher.ENCRYPT_MODE, key);
        return true;
    } catch (KeyPermanentlyInvalidatedException e) {
        return false;
    } catch (KeyStoreException | CertificateException | UnrecoverableKeyException | IOException | NoSuchAlgorithmException | InvalidKeyException e) {
        throw new RuntimeException("Failed to init Cipher", e);
    }
}

我也遇到了这个问题，另一个答案让我走上了正轨； How to Use Unsupported Exception for Lower Platform Version

我将该方法更改为；

public boolean cipherInit() {
    try {
        cipher = Cipher.getInstance(KeyProperties.KEY_ALGORITHM_AES + "/" + KeyProperties.BLOCK_MODE_CBC + "/" + KeyProperties.ENCRYPTION_PADDING_PKCS7);
    } catch (NoSuchAlgorithmException | NoSuchPaddingException e) {
        throw new RuntimeException("Failed to get Cipher", e);
    }

    try {
        keyStore.load(null);
        SecretKey key = (SecretKey) keyStore.getKey(KEY_NAME, null);
        cipher.init(Cipher.ENCRYPT_MODE, key);
        return true;
    } catch (Exception e) {
        if(e instanceof KeyPermanentlyInvalidatedException)
            return false;
        else if(e instanceof KeyStoreException|e instanceof CertificateException|e instanceof UnrecoverableKeyException|e instanceof IOException|e instanceof NoSuchAlgorithmException|e instanceof InvalidKeyException)
            throw new RuntimeException("Failed to init Cipher",e);
    }
    return false;
}

将 KeyPermanentlyInvalidatedException 的捕获 block 从 (KeyPermanentlyInvalidatedException e) 更改为 (e instanceof KeyPermanentlyInvalidatedException) 似乎出于某种原因解决了这个问题。
