Change Member Scope

Update group member roles and permissions using the Android SDK

AI Integration Quick Reference

// Change member scope (admin only)
CometChat.updateGroupMemberScope(
    "UID", 
    "GUID", 
    CometChatConstants.SCOPE_MODERATOR,
    object : CallbackListener<String>() {
        override fun onSuccess(message: String) { }
        override fun onError(e: CometChatException) { }
    })

Available Scopes:

• SCOPE_ADMIN - Full control over group
• SCOPE_MODERATOR - Can moderate members and content
• SCOPE_PARTICIPANT - Regular member (default)

Note: Only group admins can change member scopes.

Change Scope of a Group Member

Use updateGroupMemberScope() to change a member’s role. Only group Admins can change scopes.

Java

private String GUID = "GUID";
private String UID = "UID";
private String scope = CometChatConstants.SCOPE_ADMIN;

CometChat.updateGroupMemberScope(UID, GUID, scope, new CometChat.CallbackListener<String>() {
  @Override
  public void onSuccess(String successMessage) {
    Log.d(TAG, "User scope updated successfully");
  }

  @Override
  public void onError(CometChatException e) {
    Log.d(TAG, "User scope update failed with exception: " + e.getMessage());
  }
});

Kotlin

val GUID: String = "GUID"
val UID: String = "UID"
val scope: String = CometChatConstants.SCOPE_ADMIN

CometChat.updateGroupMemberScope(UID, GUID, scope, object:CometChat.CallbackListener<String>(){
  override fun onSuccess(p0: String?) {
    Log.d(TAG, "User scope updated successfully")
  }

  override fun onError(p0: CometChatException?) {
    Log.d(TAG, "User scope update failed with exception: " + p0?.message)
  }
})

This method takes the below parameters:

Parameter	Description
UID	The UID of the member whose scope you would like to change
GUID	The GUID of the group for which the member’s scope needs to be changed
scope	the updated scope of the member. This can be either of the 3 values: 1.CometChatConstants.SCOPE_ADMIN (admin) 2.CometChatConstants.SCOPE_MODERATOR (moderator) 3.CometChatConstants.SCOPE_PARTICIPANT (participant)

The default scope of any member is participant. Only the Admin of the group can change the scope of any participant in the group.

Real-Time Group Member Scope Changed Events

When a member’s scope changes, group members receive a real-time event in onGroupMemberScopeChanged() of the GroupListener class. The callback provides an Action object, the updating User, the updated User, and the Group.

Java

CometChat.addGroupListener(YourActivity.class.getSimpleName(), new CometChat.GroupListener() {
  @Override
  public void onGroupMemberScopeChanged(Action action, User updatedBy, User updatedUser, String scopeChangedTo, String scopeChangedFrom, Group group) {

  }
});

Kotlin

CometChat.addGroupListener("ListenerID", object : CometChat.GroupListener() {
  override fun onGroupMemberScopeChanged(action: Action, updatedBy: User, updatedUser: User, scopeChangedTo: String, scopeChangedFrom: String, group: Group) {

  }
})

Missed Group Member Scope Changed Events

When fetching message history, scope changes appear as Action messages with these fields:

1. action - scopeChanged
2. actionOn - User object containing the details of the user whos scope has been changed
3. actionBy - User object containing the details of the user who changed the scope of the member
4. actionFor - Group object containing the details of the group in which the member scope was changed
5. oldScope - The original scope of the member
6. newScope - The updated scope of the member

Always remove group listeners when they’re no longer needed (e.g., in onDestroy() or when navigating away). Failing to remove listeners can cause memory leaks and duplicate event handling.
