I am building an android group chat application which is using Firebase real time database and, i want to add an alert notification in it, so that when any user that installs the app would be able to receive notification in his or her android phone when ever any other user sends chat messages.
I would be very much glad if any one can help me out on this issue. Thanks in advance.

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 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!

I have completed an e-commerce app in ionic3. The problem is I want user to be notified when new offers or deals are added in our inventory. This should be a backend process, whether or not the app is open or close.
Note: There is no firebase involved.
If you want to use to get notification in same device then you can try Local notification native plugin for notification and if you want to send notification to other device then you have to use Push or FCM or Onesignal and yes this all required firebase to send push notification to generate device id/key.
Is it possible to send an individual push notification to a specific user of webview Android application?
I have a webview based Android application. Android 8 blocks all background processes and my application can not anymore check for messages every 5 minutes and to show push notifications is there are new messages. As I understand almost the only solution is to use firebase to show notifications.
My question is: can I send individual Firebase notifications to webview application users? If yes, how? People who login to my website from Android phones, enter their data in a login form that loads my website. It's not a Android login form. How can I at the same time login to Firebase and how Firebase will know that this user is already logged in if it's only a webwiew application?
A webview is not capable of directly receiving Cloud Message payloads. The only browsers that works with Cloud Messaging are those that support the Push API.
What you can do instead is receive the payload in the native layer of your Android app (using a normal Android integration with a service that receives the payload), then proxy it to your webview as needed, using webview's ability to inject javascript into it (while it's visible). This definitely is not a trivial amount of work.
I unity developer, I used "onesignal.com" to send push notification to my active users. Now please guide me is there any way to send messages to those who have un-installed my app ?
the answer is no and another thing this is not logical to send push notification after the app is uninstalled.
