Detecting a new user in sendbird Open channel - sendbird

I am creating a chat system using sendbird and want to online users in an open chat room on my view. The problem is whenever a new user "joins" an "open channel", sendbird sends me System Message without the user's object.
The only way currently is to call the MemberListQuery to find all online users.

SendBird SDK V3 now triggers "userDidEnter" callback with SendBird user object.
Please take a look at our SDK documentation!

Thanks!

How do I Trigger a Firebase Cloud Message from a Twitter Action?

A feature of my school app is announcements. I am using a twitter timeline using TwitterKit to display tweets as recent announcements.
My quest now is to setup notifications that will trigger when a tweet (i.e. an announcement) is made. This notification would preferably have the content of the tweet. I have setup the dependencies needed: the certificates, project settings, app delegate functions etc...
I recently found Firebase cloud messaging and I wanted to know how to automatically create a new message based on an action such as a tweet made.

Push Notifications with Firebase and OneSignal

I'm looking for some guidance.
I'm using Firebase as the backend server for an app I'm building and I would like to alert users when somebody has either liked or disliked some content the user generated.
I understand that Firebase offers cloud messaging through which I can target very specific users and send updates to them; I have implemented that functionality. However, I would like to send updates based on changes in the database, and, as far as I understand, FCM is not built for this purpose.
I have come across OneSignal and it seems promising. Has anybody implemented this with Firebase and could it do what I'm looking for?
Thanks!
I have it set upon such a way that when a message is send by a user to another user, a notification is also send via OneSignal. You just need to store the OneSignal userId in a node with the firebase user UID.
I you like someone's content, then that would also send a notification out directly to the other user.

Get Chat History From Zopim iOS Chat SDK

How do i get chat history for Zoipm chat iOS SDKs, i am logging using anonymous user using default controller, is there any pre-config to be set to get this.
From an end-user's perspective, there is no way of seeing a chat history. Each chat is treated more like a ticket as it creates a ticket with the transcript upon completion. A chat transcript can be sent to the end-user.
I suppose the end-user could look through their ticket history and effectively see the chats alongside their other submitted tickets.

How to open an existing message (email) programmatically on BlackBerry

I am trying to open an existing message from my application so that the native email client can display the content of said message, but I cannot find any way to do that. I have found a way to open a newly created message with
Invoke.invokeApplication(Invoke.APP_TYPE_MESSAGE,
new MessageArguments (MessageArguments.ARG_NEW, "to", "subject", "body"));
But trying to open an existing message triggers an ObjectGroupReadOnlyException.
So, how can I do this? Any suggestions?
In Blackberry SDK samples you can find a demo app using which you can understand how to read your inbox using your own application
The name of the demo is BlackberryMailDemo
I was trying to display a message (using the native email app) from a different app. Basically: provide a different inbox view, but when the user selects an email, send him to the native email app with the email opened.
In any case, it is not possible.
