Android 群组加人踢人不成功

加人或者踢人，使用AVIMConversationEventHandler eventHandler = new AVIMConversationEventHandler()监听，在以下方法中得到的conversion成员不对
@Override
public void onMemberJoined(AVIMClient client, AVIMConversation conversation, List members, String invitedBy) {
Logger.i(MessageHelper.nameByUserIds(members) + " joined , invited by " + MessageHelper.nameByUserId(invitedBy));
System.out.println("conversation : " + conversation.getMembers().size() + " members size " + members.size());
System.out.println("people joined " + MessageHelper.nameByUserIds(members));
refreshCacheAndNotify(conversation);
}
