How does my client handle this when I add an XMPP friend to me? Answer

After xmppStream is created, xmpp framework creates an xmppRoster object for you. This object is used to add or reject friend requests. Method for adding a friend:-(void) addBuddy :( XMPPJID *) jid withNickname :( NSString *) optionalName groupName :( NSString *) groupName where jid is the jid requested to add as a friend. optionalName is the nickname of a friend (displayed in the list ). GroupName is the group in which the requested friend belongs. If it does not exist, xmpp framework will help you create a new one. Consent to and rejection of friend requests. The method used is as follows:-(void) acceptBuddyRequest :( XMPPJID *) jid-(void) rejectBuddyRequest :( XMPPJID *) jid, where jid is the jid of the user applying for adding a friend.
When a friend request is received, the following xmpproster protocal method will be automatically called
-(Void) xmppRoster :( XMPPRoster *) sender didReceiveBuddyRequest :( XMPPPresence *) presence

How can I refuse to add a friend with xmpp?

Add a package filter, find the Presence package, and then send the Presence. Type. unsubscribed Type Presence package back.

AndFilter presence_sub_filter = new AndFilter (new PacketTypeFilter (Presence. class), new PacketFilter (){
@ Override
Public boolean accept (Packet packet ){
// TODO Auto-generated method stub
Presence p = (Presence) packet; // cast packet to Presence
If (p. getType (). equals (Presence. Type. subscribe )){
Return true;
}
Return false;
}
});
Connection. addPacketListener (new PacketListener (){
@ Override
Public void processPacket (Packet packet ){
// TODO Auto-generated method stub
String p_cycler = packet. getFrom ();
Presence presence_back = new Presence (Presence. Type. unsubscribed );
Presence_back.setTo (P_receiver );
Connection. sendPacket (presence_back );
}
}, Presence_sub_filter );
