I am new to gcm and I tried to connect to Cloud Connection Server(XMPP) of GCM using Smack API. It was alright at the start,
My code:
uid = “123456789”;
apiKey = “A**************B”;
XMPPTCPConnectionConfiguration.Builder config;
config.setSocketFactory(SSLSocketFactory.getDefault());
config = XMPPTCPConnectionConfiguration.builder();
config.setUsernameAndPassword(uid,apiKey);
config.setServiceName(“gcm.googleapis.com”);
config.setHost(“gcm.googleapis.com”);
config.setPort(5235);
config.setDebuggerEnabled(true);
mConnection = new XMPPTCPConnection(config.build());
mConnection.setPacketReplyTimeout(10000);
try {
mConnection.connect();
mConnection.login();
}
catch (SmackException | IOException | XMPPException e) {
System.out.println(“Exception at SmackCcsClient.init()”);
e.printStackTrace();
}
But I couldnt get past the initial handshaking process. At first I used some dummy random GCMIDs to test downstream messaging and it was showing up in the smack debug window but later on, the same code shows nothing after the following xml feed as Raw sent packets:
<stream:stream xmlns='jabber:client' to='gcm.googleapis.com' xmlns:stream='[http://etherx.jabber.org/streams](http://etherx.jabber.org/streams)' version='1.0' xml:lang='en'>
and i tried
mConnection.login(uid+"@gcm.googleapis.com",apiKey);//even though i assume its next step of the handshake.
Console prints the following errors:
org.jivesoftware.smack.SmackException$NoResponseException: No response received within reply timeout. Timeout was 10000ms (~10s). Used filter: No filter used or filter was ‘null’.
