Android java.security.NoSuchProviderException: no such provider: Crypto

public static byte[] encrypt(byte[] raw, byte[] clear) throws Exception {
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
        byte[] encrypted = cipher.doFinal(clear);
        return encrypted;
    }

        return decrypted;
    }

    public static byte[] getRawKey(byte[] seed) throws Exception {

        SecureRandom sr = SecureRandom.getInstance("SHA1PRNG", "Crypto");
        sr.setSeed(seed);

一切正常的在Android 4.3-6.1的手机上加解密，但是我用 LGE Nexus 5X (7.1.1 API 25)上发现在Android N上 google去掉了Crypto provider，意味着我们将不能继续像上面那样对数据加密填充。当然，在studio里的Logcat里会提示前往关于Android N对Crypto的解决方案：
