加密后发送短信不起作用

Question

此函数将调用另一个加密（PRINCE算法）文本消息的函数（prince.Encrypt）。但是一旦它与加密功能相关联，发送短信失败。在加密之前，该功能正常运行。

    btnSendSMS.setOnClickListener(new View.OnClickListener() 
        {
             public void onClick(View v, String args) 
                  {             
                       String phoneNo = txtPhoneNo.getText().toString();
                       String message = txtMessage.getText().toString();              
                       if (phoneNo.length()>0 && message.length()>0)
                       {
                            LongBuffer messageBuf = TooLong.messageToLongBuffer(message); 
                            messageBuf.flip();
                            long[] messageData = new long[messageBuf.remaining()];
                            LongBuffer i = messageBuf.get(messageData);
                            String v1=prince.Encrypt(i, k0, kop, k1, t);
                            sendSMS(phoneNo, v1);
