Get the conversation list

The conversation list belongs to the signed-in account. Each ConversationInfo contains list state such as unread count, latest message, pinning, and draft. Use the paged API instead of the non-paged getAllConversationList().

Retrieve a page

OpenIMClient.getInstance().conversationManager.getConversationListSplit(
    new OnBase<List<ConversationInfo>>() {
        @Override
        public void onSuccess(List<ConversationInfo> conversations) {
            mergeConversations(conversations);
        }

        @Override
        public void onError(int code, String error) {
            recordConversationListFailure(code, error);
        }
    },
    0,
    50
);

The callback returns the current List<ConversationInfo> page. Advance offset by the requested item count and deduplicate by conversationID. A page smaller than count normally indicates the end; clear paging state and reload from 0 on refresh.

Keep the list synchronized

getConversationListSplit() only creates a snapshot. Combine these callbacks in the application's single OnConversationListener:

@Override
public void onNewConversation(List<ConversationInfo> conversations) {
    mergeConversations(conversations);
}

@Override
public void onConversationChanged(List<ConversationInfo> conversations) {
    mergeConversations(conversations);
}

Both callbacks carry List<ConversationInfo> and must merge idempotently by conversationID. A user can join a group without an existing conversation, and a historical conversation can remain after leaving a group, so do not substitute the joined-group list for the conversation list.
