For my thesis, I am using Smack to log a XMPP network that uses the MUC module.
Another software is currently sending IoT sensor data into different MUC rooms.
I'd like to know for every message sent into a MUC room, which users were in that room at the time of the message. Is this possible? I could use a messageListener to every muc room, however the listener only receives a message as an argument. Therefore I could not know who is logged into the room inside the listener method.
you can get all muc message in StanzaListener in xmpp. Please follow few steps to done this
Step 1. Declare as a global variables
ChatManagerListener chatListener;
Chat chat;
StanzaListener packetListener;
Step 2. Use this code in oncreate or in fragment
Note: Make sure you have connected with chat server.
packetListener = new StanzaListener() {
#Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException, InterruptedException {
if (packet instanceof Message) {
final Message message = (Message) packet;
}
}
};
XMPP.getInstance().getConnection(acitiviy)).addAsyncStanzaListener(stanzaListener, null);
ServiceDiscoveryManager sdm = ServiceDiscoveryManager
.getInstanceFor(XMPP.getInstance().getConnection(acitiviy)));
sdm.addFeature("jabber.org/protocol/si");
sdm.addFeature("http://jabber.org/protocol/si");
sdm.addFeature("http://jabber.org/protocol/disco#info");
sdm.addFeature("jabber:iq:privacy");
Step 3. Methods for one to one chat purposer
void sendMessage(String message) {
if (chat != null) {
try {
chat.sendMessage(message);
Message msg = new Message();
msg.setTo(JidCreate.bareFrom(jid));
msg.setFrom(XMPP.getInstance().getConnection(acitiviy)
.getUser());
ChatStateExtension ext = new ChatStateExtension(
ChatState.paused);
msg.addExtension(ext);
lastComposing = System.currentTimeMillis();
chat.sendMessage(msg);
} catch (SmackException.NotConnectedException e) {
} catch (Exception e) {
}
}
}
Step 4. On destroy
XMPP.getInstance().getConnection(acitiviy)).removeAsyncStanzaListener(stanzaListener);
Hope this will help you and if you want more information take a look from here. Thankyou
Nothing prervents you from calling Multi UserCaht.getParticipants() from within the listener. But be warned: If your goal is to determine the other receivers of receivers, then this approach is fragile. I also suggest to think about using PubSub instead of MUC for your IoT use case.

Can anybody tell me how to receive message in muc using Smack 4.1.0 rc1?
I am able to send message using below code.
Message message = new Message();
message.setType(Message.Type.groupchat);
message.setBody(strMessage);
message.setTo(roomJid);
multiUserChat.sendMessage(message);
I am using below code but not able to get the message.
multiUserChat = multiUserChatManager.getMultiUserChat(roomJid);
multiUserChat.addMessageListener(new MessageListener() {
#Override
public void processMessage(Message message) {
Log.i(Constant.TAG, "processMessage");
}
});
My debugging is on and i can see that app is receiving message(D/SMACK( 6098): RECV (1):
) but listener is not getting called
Use MultiUserChat.addMessageListener(MessageListener).
send presence / join to muc before adding message listener to the muc.
then you will get muc message into the listener.
without sending presence or join to the muc, you can not get the message into the listener but you can see in the logcat.
I'm using stanza listener and able to receive MUC messages.
final StanzaListener stanzaListener = new StanzaListener() {
#Override
public void processStanza(Stanza packet) throws SmackException.NotConnectedException, InterruptedException { .. }
xmppConnection.addAsyncStanzaListener(stanzaListener, StanzaTypeFilter.MESSAGE);
When device1 is sending the message to the conference room "del#conference.jabber.org"
the message is dispalyed in the chat list as well as a duplicated message is also displayed that is being send by the conference room "del#conference.jabber.org". I'm stuck, why i'm getting duplicate message.
public void setConnection(XMPPConnection connection) {
this.connection = connection;
if (connection != null) {
PacketFilter filter = new MessageTypeFilter(Message.Type.groupchat);
connection.addPacketListener(new PacketListener() {
#Override
public void processPacket(Packet packet) {
Message message = (Message) packet;
if (message.getBody() != null) {
String fromName = StringUtils.parseBareAddress(message.getFrom());
String[] parts = fromName.split("#");
String from = parts[0].trim();
messages.add(from + ":");
messages.add(message.getBody());
// Add the incoming message to the list view
mHandler.post(new Runnable() {
public void run() {
setListAdapter();
}
});
}
}
}, filter);
}
}
The send message is on button click, which is as follows
Button send = (Button) this.findViewById(R.id.sendBtn);
send.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Message mg = muc.createMessage();
String text = textMessage.getText().toString();
mg.setBody(text);
Log.i("XMPPChatDemoActivity ", "Sending text ");
if (connection != null) {
connection.sendPacket(mg);
messages.add("Me :");
messages.add(text);
setListAdapter();
}
textMessage.setText("");
}
});
and this is what i have written to connect the conference room
muc = new MultiUserChat(connection, "del#conference.jabber.org");
muc.join("alias name","password");
output what i'm getting when sending message
me: hello
del: hello
what i want i no duplicate message when i send the message i.e
me: hello
When you're in a MUC room you receive copies of all the messages, including your own.
http://xmpp.org/extensions/xep-0045.html#message - "and reflect the message out to the full JID of each occupant."
So for MUCs (not for direct messages) you will get a duplicate if you log both on send and on receive (assuming you have sufficient access to post, etc.). Your options are, largely, either to not log it on send (which is the option most clients go for) or to attempt to do smart message matching to detect when you receive your own message and elide it. The former option ensures that everyone sees a consistent view of message ordering, which some people find very useful.
Maybe your chat server sent your message to you also?
So you add one message manually in onClickListener and then the same message received from server.
I think, it will be right not to add messages from onClickListener - add only those that server sends.
I am developing a chat using quickblox but I am having some problems when I open a new chat. Suddenly I received all the messages that others users sends to me when I was desconnected. The problem is that when I start a chat with user A, I receive the chats from users B, C, D.. in user A chat room.
I have find the way to only show the A users. But the problem is that the server has already sent to me the "disconnected" messages, so when I start a chat to B I do not receive any text because the message that the user B sent to me has been delivered (and ommitted) while I was chating with user A.
How can I do to receive the pending messages (kind of history) or to just retreive the message of the chat I am logged in?
A piece of my code:
// Create Connection.
Connection.DEBUG_ENABLED = true;
config = new ConnectionConfiguration(CHAT_SERVER);
connection = new XMPPConnection(config);
try {
connection.connect();
connection.login(chatLogin, password);
// Create Chat Manager.
chatManager = connection.getChatManager();
// Create Chat.
chat = chatManager.createChat(friendLogin, null);
// // Set listener for outcoming messages.
// chatManager.addChatListener(chatManagerListener);
// Accept only messages from
String from_messages = Integer.toString(receiver_chat_id);
PacketFilter filter = new AndFilter(new PacketTypeFilter(Message.class),
new FromContainsFilter(from_messages+"-3758#chat.quickblox.com"));
// Collect these messages
PacketCollector collector = connection.createPacketCollector(filter);
Packet packet = collector.pollResult();
PacketListener myListener = new PacketListener() {
public void processPacket(Packet packet) {
if (packet instanceof Message) {
Message msg = (Message) packet;
if(msg!=null){
// Process message
System.out.println("Rebem missatge: " +msg.getBody());
}
}
}
};
// Register the listener.
connection.addPacketListener(myListener, filter);
// Set listener for detect Receiver Status
if (connection.isConnected()){
roster = connection.getRoster();
roster.addRosterListener(new RosterListener() {
public void entriesDeleted(Collection<String> addresses) {}
public void entriesUpdated(Collection<String> addresses) {}
public void presenceChanged(Presence presence) {}
public void entriesAdded(Collection<String> arg0) {}
});
}
Make a arraylist and store the receiving offline messages into that array-list. you could add a code in your processPacket(Packet packet) function to add incoming messages to the array-list. or you could use Multimaps(Google Guava) to store all the incoming messages with the key. and when you open the activity that displays the messages from the certain person you could match the name of that person with the key(stored in multimap) and displays the message of that certain person. And the better option is to store all the incomming and outgoing message chat with the certain person so that you could show all the previous chat then you open up the activity.
//StockPriceEmitter is a "dead loop" thread which generate data, and invoke StockPriceService.onUpdates() to send data.

private LocalSession sender;
public void onUpdates(List<StockPriceEmitter.Update> updates)

for (StockPriceEmitter.Update update : updates)
{

String channelName = "/stock/" + update.getSymbol().toLowerCase(Locale.ENGLISH);
// Initialize the channel, making it persistent and lazy
bayeuxServer.createIfAbsent(channelName, new ConfigurableServerChannel.Initializer()

});
// Convert the Update business object to a CometD-friendly format
Map<String, Object> data = new HashMap<String, Object>(4);
data.put("symbol", update.getSymbol());
data.put("oldValue", update.getOldValue());
data.put("newValue", update.getNewValue());
// Publish to all subscribers
ServerChannel channel = bayeuxServer.getChannel(channelName);
channel.publish(sender, data, null); // this code works fine
//this.sender.getServerSession().deliver(sender, channel.getId(), data, null); // this code does not work
}
}
}
this line channel.publish(sender, data, null); // this code works fine works fine, now I don't want channel to publish message to all clients subscirbed with it, I want to send to a specific client, so I write this this.sender.getServerSession().deliver(sender, channel.getId(), data, null);, but it does not work, browser can't get message.
thx in advance.
I strongly recommend that you spend some time reading the CometD concepts page, in particular the section about sessions.
Your code does not work because you are sending the message to the sender, not to the recipient.
You need to pick which remote ServerSession you want to send the message to among the many that may be connected to your server, and call serverSession.deliver(...) on that remote ServerSession.
How to pick the remote ServerSession depends on your application.
For example:
for (ServerSession session : bayeuxServer.getSessions())
{
if (isAdminUser(session))
session.deliver(sender, channel.getId(), data, null);
}
You have to provide an implementation of isAdmin(ServerSession) with your logic, of course.
Note that you don't need to iterate over the sessions: if you happen to know the session id to deliver to, you can do:
bayeuxServer.getSession(sessionId).deliver(sender, channel.getId(), data, null);
Also refer to the CometD chat demo shipped with the CometD distribution, that contain a full fledged example of how to send a message to particular session.
i am building a chat application with the help of GoogleCloudMessaging(GCM).i am able to send and receive messages. my problem is when i receive messages from multiple devices at the same time, all those messages are appended to the same list-view in my broadcast receiver class. how can i separate the message based on the senders and append the current chat message to the listview. and make separate notifications for other messages based on the senders and when i click on the notification it should open the same list view with messages according to sender.
can any one give me an efficient way of doing this.if you have any sample code to handle this situation please post the code.
My current code:
public class Serious extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String action=intent.getAction();
if (action.equals("com.google.android.c2dm.intent.REGISTRATION"))
{
String registrationID=intent.getStringExtra("registration_id");
// Log.i("uo",registrationID);
String error=intent.getStringExtra("error");
String unregisterd=intent.getStringExtra("unregistered");
}
else if(action.equals("com.google.android.c2dm.intent.RECEIVE"))
{
String data1=intent.getStringExtra("data1");
String data2=intent.getStringExtra("data2");
addNewMessage(new Message(data2, false));
/* PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
new Intent(context, MainActivity.class), 0);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My Notification")
.setDefaults(Notification.DEFAULT_SOUND)
.setAutoCancel(true)
.setContentText(data1+data2);
mBuilder.setContentIntent(contentIntent);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());*/
}
}
void addNewMessage(Message m)
{
MainActivity.messages.add(m);
MainActivity.adapter.notifyDataSetChanged();
//MainActivity.getListView().setSelection(MainActivity.messages.size()-1);
}
}
You should pass in your gcm message a parameter that contains the sender id. Then, when you handle the arrived message, use that sender id to decide where to add that message. In order to show multiple notifications, pass different int values to notify. Currently you always pass 1, so a new notification overrides the old one.
