android 上AES解密是报错javax.crypto.BadPaddingException: pad block corrupted

网上看到两种方法：

1.SecretKeySpec skeySpec = new SecretKeySpec(getRawKey(key), "AES");

private static byte[] getRawKey(byte[] seed) throws Exception {
KeyGenerator kgen = KeyGenerator.getInstance("AES");
SecureRandom sr = SecureRandom.getInstance("SHA1PRNG", "Crypto");
sr.setSeed(seed);
kgen.init(128, sr); // 192 and 256 bits may not be available
SecretKey skey = kgen.generateKey();
byte[] raw = skey.getEncoded();
return raw;
}

红色的部分为注意项，不能写为SecureRandom sr = SecureRandom.getInstance("SHA1PRNG"）；

2.Cipher cipher = Cipher.getInstance("AES"); ---------4.3以上有bug

修改为

Cipher cipher = Cipher.getInstance("AES/ECB/ZeroBytePadding");
