I have a chat app like WhatsApp in Unity. I want to send user notification when he received any Chat.
What I've tried yet...
I have OnChildAdded Listener but it only works when Scene is Running on Foreground.
Simple Notifications in Unity which only shows notifications after some time delay.
How can I Keep the Firebase OnChildAdded Services running in the background and show a notification to the user when any child is added to the Chats Node? (firebase - realtime)
Unfortunately, Realtime Database will not continue to work in the background (in fact, once your Activity/game is not visible, Android and iOS may kill it to save battery life or free up memory for another app).
If you'd like to send a message to a user when your app is not running, Firebase Cloud Messaging would be the way to go.
There is a rough tutorial that may help here - although it references the Android SDK rather than the Unity one.
I hope that helps!

In this simple scenario, why would someone choose to pay for a realtime service like Firestore for delivering latest updates, when a system based on Push Notifications can work as good?
If the user is not in the app, you can refresh the page as soon as the user taps the notification or opens the app. When the app is open you can refresh when a data notification is received.
What am I missing?
Why should anyone use something like Firestore when Push Notifications seems to be enough?
I am trying to update my app's badge count number of my flutter app when receiving push notifications when the app is terminated.
The Firebase messaging background handler works fine if the app is in the background but doesn't work when the app is terminated.
I have read in the documentation :
On iOS, if the user swipes away the application from app Switcher, it must be manually reopened again for background messages to start working again.
Does it mean that on iOS there is no way to update the badge count using the firebase background handler (by the logic you implement in the handler of course, just need the handler to be called) ?
Any app do this today so i wonder why it would not be possible with Firebase Messaging.
I have actually found a solution, by using a service extension in swift and passing data as payload server side, using content-available: true in python.
Here is the documentation i have followed to implement the notification server side.
Also, there is an ongoing bug / feature request for flutter and Firebase regarding this case.
I'm about to develop an app similar to a birthday reminder and I plan to use firebase for push notifications but what makes me second question my choice is whether users will be able to receive a birthday notification if they are offline(not connected to internet for the whole birthday day). I know firebase has some offline persistence support but I'm not sure if this includes push notifications support. Are there any options to achieve that with firebase or with any other tool compatible with react native?
If the device is not connected to the internet, it is going to be impossible to deliver messages to it through Firebase Cloud Messaging or other internet protocols.
The common way to deal with such a scenario is to deliver the message to the device when the user does have an internet connection, and then only display it once it's the right time. By sending a data-only message through FCM, your application code controls exactly what happens with the message data.
There are essentially two types of notifications: in app messaging and cloud messaging. Both are offered by Firebase: In App Messaging and FCM (Firebase Cloud Messaging).
The details you've given about your app is a little bit vague but if you're asking for push notifications, then FCM does the job. FCM will send notification when the app is on background or killed (exited out). When you say device is offline I'm assuming you mean when the user isn't using the phone. Yes, the notification will still come.

As far as I understand messages on subscribed topics are received through the socket connection.
So while the app is running in the background I could create local notifications and "fake" notification that pop up on the home screen and are visible in the notification center.
But is there a way to receive topic pushes if the app is closed/not running in the background?
I'm grateful for any kind of feedback as I couldn't find any documentation regarding that specific use case.
Just to clarify: I am talking about (subscribed) topic messages in firebase NOT the firebase messages. I am used to the generic iOS push notifications handling and the involved lifecycle methods. All I need to know is how firebase topic messages can be sent via apns notifications.
With Firebase Messaging you can send notifications so the app is closed (it must be installed), basically it is configured in the AppDelegate the methods and configuration according to your need, you can see more information here Firebase Messaging
No you can’t, setup your configration in apo delegate and firebase settings, when the app is offline firebase talked directly to the APN which called the nitification center in your iphone but you don’t have access on it during the application is closed.
I have developed a simple android app using Firebase database to store stuff.
Now, I want to set up notifications for each time a button is clicked.
Each time the button is clicked, it will take some info from firebase (text mostly) and will send a notification to anyone who downloaded the app.
I understood that simply creating a notificationManager won't work as needed.
I also heard about Firebase Cloud Messaging but im pretty new to this so I must know what I should start learning to make that work out.
So, if you have any good tutorials or anything helpful, that would be great!
Thanks!
You need to receive for the FCM in android app. Refer this doc. And you need to can use database triggers in firebase cloud functions to send FCM notification, or you need to deploy a cloud http function to do so.
