Is it possible to Create New Group Summary via client?

hi,

I build android application and I want to create group inside: openfire -> User/Groups -> Groups -> Create New Group.

I wonder if I import to android application client the below class.

Openfire-master/src/java/org/jivesoftware/openfire/group

AbstractGroupProvider.java        GroupAwareMap.java

ConcurrentGroupList.java          GroupCollection.java

ConcurrentGroupMap.java           GroupJID.java

DefaultGroupPropertyMap.java      GroupManager.java

DefaultGroupProvider.java         GroupNotFoundException.java

Group.java                        GroupProvider.java

GroupAlreadyExistsException.java  JDBCGroupProvider.java

GroupAwareList.java               package-info.java

and I write someting like:

try {

                Group newGroup = objManger.getGroupManager().createGroup(name);

                if (description != null) {

                    objManger.setDescription(description);

                }

I be able to create new group?

And did I must to build plugin for openfire or I can control it from the client?

Many Thanks for any help.
