I have built a chat application using an Openfire (xmpp) server. One-to-one person chats are working fine and the messages are delivered instantly. But when we send a message inside a group, the first message gets delayed and the second message is delivered instantly.
MultiUserChatManager groupChat =
MultiUserChatManager.getInstanceFor(connection).getMultiUserChat("group_name");
groupChat.send("Message object");
Why is the first message getting delayed?
MUC Creation is
MultiUserChatManager mchatManager = MultiUserChatManager.getInstanceFor(xmpptcpConnection);
MultiUserChat mchat = mchatManager.getMultiUserChat(group);
if (!mchat.isJoined()) {
Log.d("CONNECT", "Joining room !! " + group + " and username " + username);
boolean createNow = false;
try {
mchat.createOrJoin(username);
createNow = true;
} catch (Exception e) {
Log.d("CONNECT", "Error while creating the room " + group + e.getMessage());
}
if (createNow) {
Form form = mchat.getConfigurationForm();
Form submitForm = form.createAnswerForm();
List<FormField> formFieldList = submitForm.getFields();
for (FormField formField : formFieldList) {
if(!FormField.Type.hidden.equals(formField.getType()) && formField.getVariable() != null) {
submitForm.setDefaultAnswer(formField.getVariable());
}
}
submitForm.setAnswer("muc#roomconfig_persistentroom", true);
submitForm.setAnswer("muc#roomconfig_publicroom", true);
mchat.sendConfigurationForm(submitForm);
//mchat.sendConfigurationForm(
// new Form(DataForm.Type.submit)); //this is to create the room immediately after join.
}
}
Log.d("CONNECT", "Room created!!");
return true;
} catch (SmackException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
