getMessages

public abstract void getMessages(ConversationType conversationType, String targetId, String channelId, HistoryMessageOption historyMessageOption, IRongCoreCallback.IGetMessageCallback callback)

Retrieves the historical messages of a specified conversation.

This method first attempts to retrieve historical messages from the local storage. If there are missing messages locally, it will synchronize the missing parts from the server. If the synchronization from the server fails, a non-zero errorCode will be returned, and the locally available messages will be returned via the callback. The historical message cloud storage feature must be enabled.
