Android如何从.net服务器解码Aes编码字符串？

我正在尝试解码字符串，这是服务器的响应

byte[] input = "6KzVyH0s3RyliBBAkcIrKOmripAUrDgBrm3VZR0VKkDlBTsHdOm/ONN1st/PBhquynxOjIPvgTfXJKx3aYDaARvCBmJwm1a0kfqFUcdpho+QSqpnqlDaBelL3taPKy2XPNmbOWlYUQtircPwcTrbOEUrQeUjEKqtataHw1tIp5c=".getBytes();


            String key1="12345891456";

           // byte[] keyBytes = new byte[] { 1234567891123456 };

            byte[] keyBytes = null;
            try {
                keyBytes = key1.getBytes("UTF-16LE");               

            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");

            //key.init(128);

            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC");

            System.out.println(new String(input));

            // encryption pass
            cipher.init(Cipher.ENCRYPT_MODE, key);

            byte[] cipherText = new byte[cipher.getOutputSize(input.length)];           
            int ctLength = cipher.update(input, 0, input.length, cipherText, 0);       

            // decryption pass
            cipher.init(Cipher.DECRYPT_MODE, key);

            byte[] plainText = new byte[cipher.getOutputSize(ctLength)];

            int ptLength = cipher.update(cipherText, 0, ctLength, plainText, 0);

            ptLength += cipher.doFinal(plainText, ptLength);
            System.out.println(new String(plainText));
            System.out.println(ptLength);
          }

如果出现错误，则日志为

检查这些问题；确保两侧使用相同的密码规范（包括填充）。另外，请确保对密钥使用正确的编码-UTF-16看起来不是一个好主意，并且密钥的长度为11个字符（=22字节）。
