How to get notification on firebase chat app using local notification?

How to get notification when the app is at the backgroenter code hereund or forced stopped?
I want to get a notification in the Android app using a broadcast receiver, Problem is that I have found solution when the app is opened. when app is opened I am able to receive notification. But when the app is killed or forced stopped I am not getting the notification. I want to know that how can i get notification when app is connected to the internet and get an notification even app is forced stopped.

There are two types of messages in FCM (Firebase Cloud Messaging):
Display Messages: These messages trigger the onMessageReceived() callback only when your app is in foreground
Data Messages: Theses messages trigger the onMessageReceived() callback even if your app is in foreground/background/killed
Firebase team have not developed a UI to send data-messages to your devices, yet.
When your app is closed the notification submitted to your system, and can you retrieve the data in notification when you click on notification your application is started and in your launcher activity can you get the data intent

Android Push Notification when app in background or closed

My app has push notification (FCM). When app runs in foreground,I can get data payload in onMessageReceived() function. When app runs in background or app was fully closed, onMessageReceived() function was not invoked.
My question is, is possible to get data payload when app in background or closed?
Thanks in advance!

If you want to receive data payload in your onMessageReceived() then you need to do change where you generating the notification(like at your server side),
You need to remove notification payload just need to send data payload If you send only data payload then its work like bellow one.
From
{"to":"[add your token]","notification":{"title":"[add title]","body":"[add your message]"},"priority":"high"}
TO
{"to":"[add your token]","data":{"title":"[add title]","body":"[add your message]"},"priority":"high"}
After doing this you will get notification perfectly

Push Notifications to Android App

I have an android app connected to FCM(firebase cloud messaging) for sending notifications . However , when the app is in background , it doesn't apply
custom notifications. I think this is because it does not enter OnMessageReceived method . Whats the solution for this ? As i read somewhere it can be done using HTTP Api but i am not sure of how to go about it ? Please help.Thank you.

Whether the method onMessageReceived is called is dependent on the notification payload.
See 'Handling Messages' section in FCM docs here.
Handling messages
onMessageReceived is provided for most message types, with the following exceptions:
Notification messages delivered when your app is in the background. In this case, the notification is delivered to the device’s system tray. A user tap on a notification opens the app launcher by default.
Messages with both notification and data payload, both background and foreground. In this case, the notification is delivered to the device’s system tray, and the data payload is delivered in the extras of the intent of your launcher Activity.
In summary, if the app is in foreground, then onMessageReceived will always be called. If the app is in background, then onMessageReceived will only be called if the notification payload is data only.
So to answer your question, if you must have onMessageReceived every time regardless if the app is in foreground or background state, then set your notification payload to contain data only.

How do I get a call back for notification received in android?

Is it possible/is there a reliable way to get a call back when a notification is received on the android platform? i.e. I want to record when the notification is received (not when it is later opened).

No, It's your app which receives the message so if you need things logged, then log it. Simply handle it as you like once you receive it. Note that if you use FCM with Notification message message type, then you will not be directly notified about message arrival when app is in background (notification will be automatically posted by Firebase - your app will get message payload once use taps the notification). In such case consider switching to Data messages so you will get it no matter your app is in foreground or not.
See docs: https://firebase.google.com/docs/cloud-messaging/downstream

Quickblox Android Push Notifications with app in the foreground

I am using Quickblox in my app, but I have an issue with the push notifications.
I receive the notifications while the app is in the background or close.
But while I have the app opened if I receive a message from a conversation I don't receive any push notification.
I use QBMessageListener when the user is inside the conversation, and it works, but I don't know how to receive messages from other conversations to show a notification to the user.
I supposed I would receive a push notifications, but it doesn't work.
