android.security.KeyStoreException: Key user not authenticated

使用指纹密码时,创建密钥的时候,原代码如下:

/**
     * 创建密钥
     * invalidatedByBiometricEnrollment是false的话,录入新的指纹创建的密钥不会失效
     * 默认是true,true的话,注册新指纹,密钥将失效
     * 7.0以上的系统这个参数才有效
     */
    public void createKey(boolean invalidatedByBiometricEnrollment) {

        try {
            mKeyStore.load(null);
            final KeyGenerator generator = KeyGenerator.getInstance(KeyProperties.KEY_ALGORITHM_AES, "AndroidKeyStore");
            final int purpose = KeyProperties.PURPOSE_ENCRYPT | KeyProperties.PURPOSE_DECRYPT;
            final KeyGenParameterSpec.Builder builder = new KeyGenParameterSpec.Builder(AppParam.getInstance().getKeyName(), purpose);
            builder.setBlockModes(KeyProperties.BLOCK_MODE_CBC);
            builder.setUserAuthenticationRequired(true);//每次使用这个密钥,需要指纹验证
            builder.setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_PKCS7);

//添加这个会报错:android.security.KeyStoreException: Key user not authenticated
//            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//                builder.setInvalidatedByBiometricEnrollment(invalidatedByBiometricEnrollment);
//            }


            generator.init(builder.build());
            generator.generateKey();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }

    }
我在魅蓝E(安卓7.0)的手机上测试的时候,添加上面那个条件,不是像demo写那样,判断录入新指纹,而是报错

android.security.KeyStoreException: Key user not authenticated

找了好久的问题才找到。 哭
