What are you doing to produce the error?

try {
    for (String service: MultiUserChat.getServiceNames(con)) {
    Log.i(TAG, "Service name: " + service);
                    //Get the list of rooms under this service
                    for (HostedRoom room: MultiUserChat.getHostedRooms(con,"")) {
                        Log.i(TAG, "\tName: " + room.getName());
                        Log.i(TAG, "\tRoom JID: " + room.getJid());
                        //Get the detail information on the room 
                        RoomInfo info = MultiUserChat.getRoomInfo(con, room.getJid());
                        Log.i(TAG, "\tDescription: " + info.getDescription());
                        Log.i(TAG, "\tOccupant: " + info.getOccupantsCount());
                        Log.i(TAG, "\tPassword: " + info.isPasswordProtected());
                    }
                }
            } catch (XMPPException e) {
                Log.e(TAG, e.getMessage(),e);
            }

What is the expected output?
Collection of Service name and Room List
What do you see instead? (Please attach a debug enabled logcat)

What version of aSmack / Android / Device do you use?
asmack-jse-buddycloud-2010.12.11.jar
What server do you use? Is there a public server to reproduce the problem?

What else might help us to reproduce and hunt down the problem?

I had the same problem and the solution suggested at 
http://community.igniterealtime.org/message/201866#201866 solves the matter.

It has to do with having to add all the ExtensionProviders to the 
ProviderManager explicitly.
