XMPP - Using lib Smack remove user from group(conference) in MUC

We are integrating MUC in our app for group chat. where we can create group(conference) and adding members. Questions are-
Removed member still getting group messages. What is proper way of remove a member from group?
How to get total members of group (online/offline)?
We are using following methods to remove a members-
public void kickOutRoomMember(String groupJid, String memberNickName) {
MultiUserChat muc;
try {
if (manager == null) {
manager = MultiUserChatManager.getInstanceFor(connection);
}
muc = manager.getMultiUserChat(groupJid);
muc.kickParticipant(memberNickName, "");
} catch (Exception e) {
e.printStackTrace();
}
}
public void removeOutRoomMember(String groupJid, String memberNickName) {
MultiUserChat muc;
try {
if (manager == null) {
manager = MultiUserChatManager.getInstanceFor(connection);
}
muc = manager.getMultiUserChat(groupJid);
muc.banUser(memberNickName, "");
} catch (Exception e) {
e.printStackTrace();
}
}

Theorically you are right.
Just check
If user who invokes banUser has grants to do it
to pass bare
jid and not memberNickName as first parameter in method.
javadoc
muc.banUser("Mickey Mouse", ""); //does not works
muc.banUser("mickeymouse#server","") // will works

Install "Rest API" plugin.
Rest API plugin provides all the API related group. Create Or delete a group, Add or remove a member from a group, get all members of group etc..

Forbidden in Call connection Android Pjsip Sip library

How to perform call in Pjsip Android with local server?
I used
User-Agent: Pjsua2 Android 2.6-svn
I made successful registraion after which i tried to call but it throws forbidden(503)
My Registraion Code :
AccountConfig accCfg = new AccountConfig();
accCfg.setIdUri("sip:localhost");
accCfg.getNatConfig().setIceEnabled(true);
accCfg.getVideoConfig().setAutoTransmitOutgoing(true);
accCfg.getVideoConfig().setAutoShowIncoming(true);
//Like 123.12.12.23
accCfg.getRegConfig().setRegistrarUri("sip:172.16.4.124");
AuthCredInfoVector creds = accCfg.getAuthCreds();
creds.clear();
if (username.length() != 0) {
creds.add(new AuthCredInfo("Digest", "*", "abc#172.16.4.124", 0,
"123"));
}
StringVector proxies = accCfg.getSipConfig().getProxies();
proxies.clear();
if (proxy.length() != 0) {
proxies.add("sip:172.16.4.124");
}
accCfg.getSipConfig().setProxies(proxies);
/* Enable ICE */
accCfg.getNatConfig().setIceEnabled(true);
try {
account.add(accCfg);
} catch (Exception e) {
e.printStackTrace();
Log.i(TAG, "Exception in Dialog");
}
}
For Making call I used
public void makeCall(View view) {
if (buddyListSelectedIdx == -1)
return;
/* Only one call at anytime */
if (currentCall != null) {
return;
}
HashMap<String, String> item = (HashMap<String, String>) buddyListView.
getItemAtPosition(buddyListSelectedIdx);
String buddy_uri = item.get("uri");
MyCall call = new MyCall(account, -1);
SendInstantMessageParam param = new SendInstantMessageParam();
param.setContent("Hello Pjsip");
param.setContentType("text");
CallOpParam prm = new CallOpParam(true);
try {
call.makeCall(buddy_uri, prm);
// call.delete();
// call.sendInstantMessage(param);
} catch (Exception e) {
e.printStackTrace();
call.delete();
return;
}
currentCall = call;
showCallActivity();
}
I am able to connect call with sip default client like sip:localhost and other sip provider like linphone but getting forbidden with our server.
Experts please help.

Thanks alot to myself, finally i get the solution after 3 day workout,
had missing portnumber for my amazon server, makes me to get connected and made a sippy call between sip ends.

Getting all users from an openfire server using smack android

i have a openfire server running on my localhost and i am successfully able to send and receive messages to registered users. however i am not been able to get all users from server. i am logged in with user that doesn't have a administration access. so do i need to give any permission on server side?
The code i am using for getting all users is..
if ( xmpp.getConnection()== null || !xmpp.getConnection().isConnected())
return;
try {
UserSearchManager usm = new UserSearchManager(xmpp.getConnection());
Form searchForm = usm.getSearchForm("search." + xmpp.getConnection().getServiceName());
Form answerForm = searchForm.createAnswerForm();
UserSearch userSearch = new UserSearch();
answerForm.setAnswer("Username", true);
answerForm.setAnswer("search", userName);
ReportedData data = userSearch.sendSearchForm(xmpp.getConnection(), answerForm, "search." + xmpp.getConnection().getServiceName());
for (ReportedData.Row row : data.getRows())
{
arrayList.add(row.getValues("Username").toString());
}
} catch (Exception e) {
e.printStackTrace();
}
i tried some solutions that shows to use Roster class, however that is also not helping me. Can anyone show what i am doing wrong or if i need to give any permission as i am not logged in as admin?
The error i am getting is..
org.jivesoftware.smack.XMPPException$XMPPErrorException: XMPPError: remote-server-not-found
Thanks :)

This is how I am getting all users from openfire
You actually have to pass wildcard(*) for the username
Here's the working code
Utils.getConnection() - my xmpp connection
public static void getAllXmppUsers()
{
try {
UserSearchManager manager = new UserSearchManager(Utils.getConnection());
String searchFormString = "search." + Utils.getConnection().getServiceName();
Log.d("***", "SearchForm: " + searchFormString);
Form searchForm = null;
searchForm = manager.getSearchForm(searchFormString);
Form answerForm = searchForm.createAnswerForm();
UserSearch userSearch = new UserSearch();
answerForm.setAnswer("Username", true);
answerForm.setAnswer("search", "*");
ReportedData results = userSearch.sendSearchForm(Utils.getConnection(), answerForm, searchFormString);
if (results != null) {
List<ReportedData.Row> rows = results.getRows();
for (ReportedData.Row row : rows) {
Log.d("***", "row: " + row.getValues("Username").toString());
}
} else {
Log.d("***", "No result found");
}
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
}

Try this code. I tweak this code from this answer
UserSearchManager usm= new UserSearchManager(xmpp.getConnection());
Form searchForm = usm.getSearchForm("search." +xmpp.getConnection().getServiceName());
Form answerForm = searchForm.createAnswerForm();
answerForm.setAnswer("Username", true);
answerForm.setAnswer("search", userName);
ReportedData data = usm
.getSearchResults(answerForm, "search." + xmpp.getConnection().getServiceName());
if (data.getRows() != null) {
for (ReportedData.Row row: data.getRows()) {
for (String jid:row.getValues("jid")) {
System.out.println(jid);
}
}
}

Smack is used to create a client. A client is used by one user. A user typically does not have access to all users of the server. Users do have contact lists, or rosters though, where you an add other users.

How to create and send Bye message from client to server in jainsip android?

I have tried jainsip example in Mobicents restcomm-android-sdk.Its worked for me but i am not able create bye message from client side properly.
I created a Bye Message class like this
public class Bye {
public Request MakeRequest(SipManager sipManager) throws ParseException,
InvalidArgumentException {
AddressFactory addressFactory = sipManager.addressFactory;
SipProvider sipProvider = sipManager.sipProvider;
MessageFactory messageFactory = sipManager.messageFactory;
HeaderFactory headerFactory = sipManager.headerFactory;
// Create addresses and via header for the request
Address fromAddress = addressFactory.createAddress("sip:"
+ sipManager.getSipProfile().getSipUserName() + "#"
+ sipManager.getSipProfile().getRemoteIp());
fromAddress.setDisplayName(sipManager.getSipProfile().getSipUserName());
Address toAddress = addressFactory.createAddress("sip:"
+ sipManager.getSipProfile().getSipUserName() + "#"
+ sipManager.getSipProfile().getRemoteIp());
toAddress.setDisplayName(sipManager.getSipProfile().getSipUserName());
Address contactAddress = sipManager.createContactAddress();
ArrayList<ViaHeader> viaHeaders = sipManager.createViaHeader();
URI requestURI = addressFactory.createAddress(
"sip:" + sipManager.getSipProfile().getRemoteEndpoint())
.getURI();
// Build the request
CallIdHeader callIdHeader = sipManager.sipProvider.;
final Request request = messageFactory.createRequest(requestURI,
Request.BYE, sipProvider.getNewCallId(),
headerFactory.createCSeqHeader(1l, Request.BYE),
headerFactory.createFromHeader(fromAddress, "c3ff411e"),
headerFactory.createToHeader(toAddress, null), viaHeaders,
headerFactory.createMaxForwardsHeader(70));
// Add the contact header
request.addHeader(headerFactory.createContactHeader(contactAddress));
ExpiresHeader eh = headerFactory.createExpiresHeader(300);
request.addHeader(eh);
// Print the request
System.out.println(request.toString());
return request;
// Send the request --- triggers an IOException
// sipProvider.sendRequest(request);
// ClientTransaction transaction = sipProvider
// .getNewClientTransaction(request);
// Send the request statefully, through the client transaction.
// transaction.sendRequest();
}
}
Call it From SipManager class as
public void disconnectCall() throws NotInitializedException {
// TODO Auto-generated method stub
if (!initialized)
throw new NotInitializedException("Sip Stack not initialized");
this.sipManagerState = SipManagerState.BYE;
Bye byeRequest = new Bye();
Request r=null ;
try{
r = byeRequest.MakeRequest(this);//byeRequest.MakeRequest(SipManager.this);
final ClientTransaction transaction = this.sipProvider
.getNewClientTransaction(r);
Thread thread = new Thread() {
public void run() {
try {
transaction.sendRequest();
} catch (SipException e) {
e.printStackTrace();
}
}
};
thread.start();
} catch (TransactionUnavailableException e) {
e.printStackTrace();
}catch (InvalidArgumentException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
}
}
I have got 481 error code as response.I think I have missed the current callid field in the bye message.I have searched for it but not found from sipmanager class.pls help.

Nidhin,
BYE messages are always inside a SIP dialog, so you don't have to create a new message from scratch. Instead, you just need to get ahold of the dialog you want to terminate, create a request of type BYE from that and send it. JAIN will take care of the rest.
For an example, you can check the code at the Mobicents restcomm-android-sdk repo, method sendByeClient():
https://github.com/Mobicents/restcomm-android-sdk/blob/master/sipua/src/main/java/org/mobicents/restcomm/android/sipua/impl/SipManager.java#L931
Please also keep in mind that the JAIN SIP example has been obsoleted by Messenger example that uses the Restcomm Android Client SDK which offers a simpler API. Here's its code for your reference:

How to get offline message of group chat from Openfire

Is any way in xmpp that i get offline message of MultiUserChat, when my user login and join room.
I want implement group chat like WhatsApp, Is any other way to implement this please suggest
Thanks in advance

At least in ejjaberd when you enter the chat group, you have to enter your last timestamp, given that timestamp you will receive the messages from that moment.
Save the timestamp from your last message, and when you enter to your room, like the following:
MultiUserChat muc = new MultiUserChat(mConnection, room_name);
Log.d(TAG, "JOINING => " + room_name);
DiscussionHistory history = new DiscussionHistory();
if (mLastMessageDate == null)
history.setMaxStanzas(300);
else
history.setSince(mLastMessageDate); //timestamp from your last message
muc.join(mNickName, null, history,
SmackConfiguration.getDefaultPacketReplyTimeout());
Hope it helps

First declare a MultiUserChat this way
private static MultiUserChat muc = null;
then in your oncreate method instantiate it this way
muc = new MultiUserChat(CONNECTION, room);
try {
muc.join(USERJID);
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
}
and call this method in the beginning of your app
void setMessageListner() {
muc.addMessageListener(new PacketListener() {
#Override
public void processPacket(Packet packet) throws SmackException.NotConnectedException {
Message msg = (Message)packet;
msg.setSubject(msg,getBody);
Logger.i("Received message : "+msg.getBody()+" From "+msg.getSubject());
});
}
this way whenever the user get into a GroupChat he will get the last Messages of the group
