How to handle add request in smack API - smack

Question

I use Smack API to write my Google talk Client . Now i need to handle add request for this .
I set SubscriptionMode to manual & now I have to registering a listener for presence packets but i don't know how !!
can any body help ?

Answer 1

I have not tried it yet, but I guess the below should work. If using the manual mode, a PacketListener should be registered that listens for Presence packets that have a type of Presence.Type.subscribe.
First set the roster:
Roster roster = connection.getRoster();
roster.setSubscriptionMode(Roster.SubscriptionMode.manual);
Then add a packet listner to the above connection, eg :
connection.addPacketListener(new SubscriptionListener(), new PacketFilter(){
public boolean accept(Packet packet) {
if(packet instanceof Presence)
if(((Presence)packet).getType().equals(Presence.Type.subscribe))
return true;
return false;
}});
The above code just returns true for all requests, But you can customize it i.e set it to true or false based on user GUI input.

public static void admitFriendsRequest() {
connection.getRoster().setSubscriptionMode(
Roster.SubscriptionMode.manual);
connection.addPacketListener(new PacketListener() {
public void processPacket(Packet paramPacket) {
System.out.println("\n\n");
if (paramPacket instanceof Presence) {
Presence presence = (Presence) paramPacket;
String email = presence.getFrom();
System.out.println("chat invite status changed by user: : "
+ email + " calling listner");
System.out.println("presence: " + presence.getFrom()
+ "; type: " + presence.getType() + "; to: "
+ presence.getTo() + "; " + presence.toXML());
Roster roster = connection.getRoster();
for (RosterEntry rosterEntry : roster.getEntries()) {
System.out.println("jid: " + rosterEntry.getUser()
+ "; type: " + rosterEntry.getType()
+ "; status: " + rosterEntry.getStatus());
}
System.out.println("\n\n\n");
if (presence.getType().equals(Presence.Type.subscribe)) {
Presence newp = new Presence(Presence.Type.subscribed);
newp.setMode(Presence.Mode.available);
newp.setPriority(24);
newp.setTo(presence.getFrom());
connection.sendPacket(newp);
Presence subscription = new Presence(
Presence.Type.subscribe);
subscription.setTo(presence.getFrom());
connection.sendPacket(subscription);
} else if (presence.getType().equals(
Presence.Type.unsubscribe)) {
Presence newp = new Presence(Presence.Type.unsubscribed);
newp.setMode(Presence.Mode.available);
newp.setPriority(24);
newp.setTo(presence.getFrom());
connection.sendPacket(newp);
}
}
}
}, new PacketFilter() {
public boolean accept(Packet packet) {
if (packet instanceof Presence) {
Presence presence = (Presence) packet;
if (presence.getType().equals(Presence.Type.subscribed)
|| presence.getType().equals(
Presence.Type.subscribe)
|| presence.getType().equals(
Presence.Type.unsubscribed)
|| presence.getType().equals(
Presence.Type.unsubscribe)) {
return true;
}
}
return false;
}
});
connection.getRoster().addRosterListener(new RosterListener() {
public void presenceChanged(Presence presence) {
System.out.println(presence.getFrom() + "presenceChanged");
}
public void entriesUpdated(Collection<String> presence) {
System.out.println("entriesUpdated");
}
public void entriesDeleted(Collection<String> presence) {
System.out.println("entriesDeleted");
}
public void entriesAdded(Collection<String> presence) {
System.out.println("entriesAdded");
}
});
}
