Create a Group

Create a Group

In other words, as a logged-in user, how do I create a public, private or password-protected group?

You can create a group using createGroup() method. This method takes a Group object as input.

To create an object of Group class, you can use either of the below two constructors:

1. new Group(String GUID, String name, String groupType, String password)
2. new Group(String GUID, String name, String groupType, String password, String icon, String description)

The groupType needs to be either of the below 3 values:

1.CometChatConstants.GROUP_TYPE_PUBLIC (public)

2.CometChatConstants.GROUP_TYPE_PASSWORD (password)

3.CometChatConstants.GROUP_TYPE_PRIVATE (private)

Java

private String GUID = "GUID";
private String groupName = "Hello Group!";
private String groupType = CometChatConstants.GROUP_TYPE_PUBLIC;
private String password = "";

Group group = new Group(GUID, groupName, groupType, password);

CometChat.createGroup(group, new CometChat.CallbackListener<Group>(){
  @Override
  public void onSuccess(Group group) {
    Log.d(TAG, "Group created successfully: " + group.toString());
  }
  @Override
  public void onError(CometChatException e) {
    Log.d(TAG, "Group creation failed with exception: " + e.getMessage());
  }
});

Kotlin

val GUID:String="GUID"
val groupName:String="Hello Group"
val groupType:String=CometChatConstants.GROUP_TYPE_PUBLIC
val password:String=""

val group=Group(GUID,groupName,groupType,password)

CometChat.createGroup(group,object :CometChat.CallbackListener<Group>(){
  override fun onSuccess(p0: Group?) {
    Log.d(TAG, "Group created successfully: " + p0?.toString())
  }
  override fun onError(p0: CometChatException?) {
    Log.d(TAG, "Group creation failed with exception: " + p0?.message)
  }
})

The createGroup() method takes the following parameters:

Parameter	Description
group	An instance of Group class

After the successful creation of the group, you will receive an instance of Group class which contains all the information about the particular group.

Warning

GUID can be alphanumeric with underscore and hyphen. Spaces, punctuation and other special characters are not allowed.
