SSLHandleShakeEception

[2da...@gmail.com]

Hi.

 

My GCM test server works well on my home computer but it doesn't work on my office computer.

Some SSL exceptions occurs when I try to send a message to client.

Is this a firewall problem?

 

 

 

 

Code :

 

                Message message = new Message.Builder()
                .collapseKey(
                        String.valueOf(Math.random() % 100 + 1))
                       
                .delayWhileIdle(true).timeToLive(3)
                .addData("no", "1")
                .addData("title", "Hello")
                .addData("msg", msg).build();
               
                try {                            
                    System.out.println("send! : " + regId);
                    Result result = mSender.send(message, regId, 5);

                    System.out.println("result : " + result.getCanonicalRegistrationId());
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } 

 

 

Exception
