I am investigating about React Native and Firebase Cloud Messaging. In the document, I see that has 2 types of message can be send to client is:
Notification message ( Or Notification and data message )
Data - only message
The first one can be trigger by client using onNotification, and it only trigger if the app on foreground, if in background no way to trigger that has a notification. Just onNotificationOpened can be fired.
The second is inverse, the app can trigger on foreground and background. In case the app has been closed/swiped, on Android luckily it can be triggered also by using a Handler background. But on iOS if the app closed/swiped that no way until we open app again.
The problem is what type of 2 message above that I can use to listen the notification coming, and how it can work if app in foreground, background and closed.
Hope someone can help me about this.

im developing a cordova app with firebase cloud messaging. So the plugin i used is cordova-plugin-firebase-messaging.
The requirement is i need to have the voice notification (phone to read the text out loud when receiving notification). im doing this by using
cordova-plugin-texttospeech
However, I can only do this when the app is in foreground using onMessage function :
cordova.plugins.firebase.messaging.onMessage(callback); <= i put the TTS function in the callback
However, when the app is in background, this not works:
cordova.plugins.firebase.messaging.onBackgroundMessage(callback); <= put the TTS function not works, because the callback only triggered when user tapped the notification. I want it triggered as soon as they receive it
Anybody has any idea how to do this ?
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
Firebase Push notification for Android App, starts the app when received the message while App is not running (killed), even without clicking at the notification. Does any one knows if this is the default Android behavior or there is some settings I need to change?
I'm still not clear on what you mean by open up the app (start).
Here is what I see when a notification-only message is sent to an app that is not in memory (version 11.8.0):
An instance of the app is created. This occurs even when the app does not define a service that extends FirebaseMessagingService.
If the app does define a FirebaseMessagingService, the service is created and destroyed. onMessageReceived() is not called.
In both cases, all processing occurs in the background; no activity is started until the user taps on the notification.
These observations are based on log messages output from my messaging service and Application instance.
While the descriptions in the documentation, such as FCM automatically displays the message to end-user devices on behalf of the client app, correctly indicate that the handling of the message is done "by the system", they don't mention that creation of an app instance is a side effect of that processing.
I have activated push notifications in my application and I have done all the settings with Google and Apple to be able to send from the Appcelerator Dashboard.
I can receive notifications on both Android and iOS without any problems.
In iOS, when i click the notification from the notification center, the application opens and the callback function of Ti.Network.registerForPushNotifications is executed automatically.
The problem is that in Android, the function assigned to the callback event of the cloudPush module is not executed, I understand that it will be because when opening the application the listener is not yet created.
If I receive the notification when the application is open the callback function runs smoothly.
Reading in documentation of Android seems to me to understand that the notification is included in the extras of the intent when opening the application, but I am not clear what extra is, since in Appcelerator I do not find any function to obtain all the extras.
Someone could give me an idea of how to get the payload, whether or not when I click the notification the app is in the background, as if it is totally closed?
Thanks in advance.
I am trying to implement a functionality wherein users get notification messages even when the app is not running (neither in foreground nor in background). Companies like Amazon do send notifications and they show up in the notification tray - when tapped, the app opens or whatever intent the message carried with it.
I have been able to implement notification handling when the app is in foreground and background... but when the app is not running, there are no notification messages received at all!
From what I searched around, I think there needs to be a Service running in the background that keeps listening to notification messages - because a service is destroyed when the app is closed. Am I going in the right direction?
Can someone point me to some code that implements or highlights the same.
FIXED... actually.. the problem was MIUI.. Its security app by default disabled autostart for apps.. which blocks notifications from being shown in the system tray when the app is not running.

I you have to see the implementation of FCM for android from https://firebase.google.com/docs/cloud-messaging/
I shows complete understanding of instant notification.
