I am trying to send push notification to both android and ios. On Android push notification is handled by data while on ios notification is required in payload to display the notification.
But if notification part is added and if user is subscribed to the channel on both the device. On Android it show 2 messages created by notification part of payload.
Any particular way to send the payload from firebase. So that it can run on both the devices.
Thanks in advance
Like Frank said, Firebase does support sending messages to both iOS and Android.
If you send a notification message with a data payload (so both notification and data) the Android client will either display the auto generated notification based on the notification payload if the app is in the background or be passed to the onMessageReceived callback where you have the option to generate a notification based on the data and/or notification payloads if you wish if the app is in the foreground. There will not be two notifications generated.

In my current app notifications are displayed by the FCM automatically as I am using notification message. Now I need to use Data message so that I can handle notifications myself, when the app is in background. The problem here is that if
I send only data message current version of the app will not show the notifications(as I am not sending notification message)
I send both notification and data message then I cannot handle notifications as when the app will be background FCM will automatically display the message based on notification data.
Is there any way so that I can use Data message without breaking the current app functionality and will be able to handle the notifications by myself?
When sending notification through Firebase API calls onMessageReceived() even when the app is not running or killed but when sending through Firebase Console does not invoke onMessageReceived() when app is killed ?
FCM provide two types of messages .
Notification messages -sometimes thought of as "display messages." These are handled by the FCM SDK automatically.
2.Data messages-which are handled by the client app.
Notification messages are delivered to the notification tray when the app is in the background. For apps in the foreground, messages are handled by onMessageReceived():
For more information read FCM messeges
You have to add some key-value pairs as a data payload from the Firebase Console. while composing message for notification you have to select Advanced options and then add some data as a key value.
Once the app will get data notification, then the notification will be displayed in both the modes(background/killed and foregroud).
Inside Firebase console(Compose message) :
Advances options --> Add custom data(with key and value) --> Send
Now that services are not running in the background, what is the proper way to generate and display your own notification from a push data payload? Is that possible anymore? I want the notification to have a different look and feel depending on the data payload. My GCM version of the app works fine, but my FCM version does not. Any thoughts?
When you send the push data, are you including both a "data" payload and a "notification" payload?
Check the documentation on receiving messages in Android. If you send your FCM messages with only a "data" payload, then you can implement onMessageReceived() and that code will receive all notifications, both when the app is in the foreground and when it is in the background.
In your onMessageReceived() method, build your own notification in whatever style you want. You can vary the style depending on the content of the "data" payload. If you aren't familiar with building your own notifications, here is the documentation.
I am trying to migrate to Firebase cloud messaging from GCM and I noticed that when the application is not running the notifications are coming in the notifications tray. With GCM this was not the case, it was up to the developer to show a notification or not. I want to have similar behavior with FCM where when the app is running I want to silently handle the push message instead of having user to click on the notification and start the app. How can I achieve that.
Thanks,
P
Firebase Cloud Messages has two types of messages:
Notification Message: this type of message has the same behavior as the GCM messages
FCM automatically displays the message to end-user devices on behalf of the client app. Notification messages have a predefined set of user-visible keys
Data Message: this type has the behavior you described above.
Client app is responsible for processing data messages.
Data messages have only custom key-value pairs.
To send data messages you need to use the HTTP API [for Data Message]. (quoted from Arthur)

How I can get some data from push notification to my app? for example from my app I send some data with push notification. when my friend get that push notification he must tap on it and my app will automatically open and app must get that data from push. Is any way to do that?
