TripleDES and Android

Hello, I have problems with this code

Code: Select all
public static byte[] decryptByte(byte[] cryptoByte,
         Context applicationContext) throws IllegalBlockSizeException, BadPaddingException, NoSuchAlgorithmException, UnsupportedEncodingException, InvalidKeyException, InvalidAlgorithmParameterException, NoSuchPaddingException {
      final SecretKey key = new SecretKeySpec(new UniqueIdentifier(
            applicationContext).getUuidBytes(), "DESede");
      
      final IvParameterSpec iv = new IvParameterSpec(new byte[8]);

      final Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");

      cipher.init(Cipher.DECRYPT_MODE, key, iv);
      
      return cipher.doFinal(cryptoByte);
   }


when I call the method doFinal (-----) javax.crypt.BadPaddingException: pad block corrupted !!!

Browsing on google I found the problem is BoucyCastle. Can be true?

Someone can help me?
