Sorry for my english is very poor. I use Smack 4.1.3
public class RosterGetInstanceFor {
protected static ConnectionListener connectionListener = new ConnectionListener() {
@Override
public void authenticated(XMPPConnection connection, boolean arg1) {
if (connection != null && connection.isAuthenticated()) {
Roster roster = Roster.getInstanceFor(connection);
System.out.println("roster.getGroups().size() ="
+ roster.getGroups().size());
System.out.println("roster.getEntries().size()="
+ roster.getEntries().size());
}
}
@Override
public void connected(XMPPConnection arg0) {
// TODO Auto-generated method stub
}
@Override
public void connectionClosed() {
// TODO Auto-generated method stub
}
@Override
public void connectionClosedOnError(Exception arg0) {
// TODO Auto-generated method stub
}
@Override
public void reconnectingIn(int arg0) {
// TODO Auto-generated method stub
}
@Override
public void reconnectionFailed(Exception arg0) {
// TODO Auto-generated method stub
}
@Override
public void reconnectionSuccessful() {
// TODO Auto-generated method stub
}
};
public static void main(String[] args) throws SmackException, IOException, XMPPException, InterruptedException {
XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration
.builder();
builder.setUsernameAndPassword("reader","reader");
builder.setServiceName("wpw-pc");
builder.setHost("wpw-pc");
builder.setCompressionEnabled(false);
builder.setResource("Hyperbola");
builder.setSecurityMode(SecurityMode.disabled);
AbstractXMPPConnection connection = new XMPPTCPConnection(builder.build());
connection.addConnectionListener(connectionListener);
connection.connect();
connection.login();
Thread.sleep(3000); // must
Roster roster = Roster.getInstanceFor(connection);
System.out.println("roster.getGroups().size() ="
+ roster.getGroups().size());
System.out.println("roster.getEntries().size()="
+ roster.getEntries().size());
Thread.sleep(5000);
connection.disconnect();
}
I run the above code，output is：
roster.getGroups().size() =0
roster.getEntries().size()=0
roster.getGroups().size() =2
roster.getEntries().size()=4
How can I get groups and entries in function authenticated?
Also， I must add the code : Thread.sleep(3000)
If I remove this line ,output is :
roster.getGroups().size()=0
roster.getEntries().size()=0
roster.getGroups().size()=0
roster.getEntries().size()=0
Thanks and Regards,
