I'm trying to send a payload using GCM that can be handled on the background or foreground by clients using Android and iOS. The messages are delivered to clients using both platforms that are subscribed in a topic.
Because I need the iOS app to handle the data even when the app is on the background or closed, I'm setting "content_available": true, which works as expected on iOS.
However, when I add that parameter, Android does not handle the received data and instead displays a blank notification.
Here's an example payload:
{
"to": "/topics/946",
"content_available": true,
"data": {
"time": "2016-02-04 18:33:08",
"message": "Hello",
"msgType": "chat",
"senderId": "50",
"senderName": "John"
}
}
The documentation says that data messages should wake the Android app anyway:
On iOS, use this field to represent content-available in the APNS
payload. When a notification or message is sent and this is set to
true, an inactive client app is awoken. On Android, data messages wake
the app by default. On Chrome, currently not supported.
What am I doing wrong?
EDIT: I've already tried using "priority":"high", which does not make any difference.

I'm using Capacitor for my App, I have an use case similar to whatsapp, when users receive a new message if your app is in background, you receive FCM notification in the notification tray, later if user open that particular chat directly by opening the app(without clicking on the notification), i'd like to clear that notification from the notification tray.
so here's what I thought
get active notification
find the active chat notifications by filtering extra data sent by FCM
clear those notifications programatically
however android's notificationManager.getActiveNotifications doesn't seem to provide access to FCM data.
below is the payload i'm posting to FCM(i want to use chatId and type in data section to clear active notifications).
{
"android": {
"priority": "high"
},
"notification": {
"title": "you have a new message from XYZ",
"body": "hello"
},
"data": {
"messageId": "62971793-0111-4c9b-bbb2-bb78262a0543",
"chatId": "631e162f5f286c23d13e06d5",
"type": "CHAT_NEW_MESSAGE"
},
"token": "fcmToken"
}
Here's the capacitor plugins Android Logic to get the delivered/active notification.
how can I achieve above use case?
I am trying to send notifications to both Android and iOS devices using FCM. The front end was coded with Flutter. I am working with Typescript/NestJS at the back end. For some reason, iOS devices receive all the notifications with a push notification/pop-up but Android devices sometimes don't. Strangely, the notifications ALL arrive at the test device INBOXES. It's just that sometimes, Android devices do not show a pop-up/push notification.
Targeting users thru a Firebase topic works as expected: push notifications do arrive for Android and iOS. I do have to find and filter out the users to target before sending the target device IDs to FCM. I am confident my filters are correct. The notifications arrive in the app inbox for both Android and iOS after my filtering. Also, changing the device ID/token in my database causes an error from FCM:
{"code":"messaging/registration-token-not-registered","message":"Requested entity was not found."}
If I revert the data to its original values, the app runs fine. I've checked and compared the data I pass to Node.js' FCM module and it looks fine. Here, messaging is an instance of firebaseAdmin.messaging().
param = {
"android": {
"data": {
"id": "67bcd478-f643-4c9e-848a-be354a6b85d4",
"icon": "default",
"title": "Test",
"body": "Direct From Playground"
}
},
"apns": {
"payload": {
"aps": {
"id": "67bcd478-f643-4c9e-848a-be354a6b85d4",
"icon": "default",
"title": "Announcements",
"body": "Direct From Playground",
"alert": {
"title": "Announcements",
"body": "Direct From Playground"
}
}
}
}
}
messaging.sendMulticast({
tokens: value as string[],
...param,
});
Again, the code above sometimes successfully triggers push/pop-up notifications on Android devices but ALWAYS on iOS. Could this be a problem for the front-end handling of my data? Am I missing some parameters?
I'm trying to get push notifications running with React Native on iOS and Android.
To do so I am using firebase, as that seemed to be very convenient.
On Android I managed to show notifications when the app is in the foreground and at least show a log when the app is in the background, meaning I can process them.
On iOS I have not managed to do any of those, not from our custom backend in aws (via SNS), nor from firebase console with fcm token. What interestingly worked, was to show a badge on the ios app icon when sending broadcast messages to all users. So something seems to be received on the phone.
Now looking into this a little deeper I found that iOS needs notifications in the following format:
{
"Simulator Target Bundle": "com.compass.SomeExampleApp",
"aps": {
"badge": 0,
"alert": {
"title": "Push Notification Test",
"subtitle": "Hey! 👋",
"body": "Is this working?",
},
"sound":"default"
}
}
At least this is how you can test them on the sim.
1. Does it mean that I have to send the notifications in that same format? Or can it be something like:
{
"data":{},
"apns": {
"Simulator Target Bundle": "com.company.Example",
"aps": {
"alert": {
"body": "Wellcome to MyApp!",
"title": "MyApp"
}
}
}}
2. How can I send a format that iOS AND Android can read, show on screen and process in background if necessary?
Since we are sending only data messages I think this might be part of the issue, if I look at our backend.
Still when sending from firebase I am not able to show anything on screen on ios Device. Any hint?
I found a solution that actually works on both platforms although it is a bit weird since it seems to be outdated. Code needs to look like this to send to both iOS and Android:
{ "GCM": "{ \"notification\" : {\"content_available\" : true }, \"data\": { \"body\": \"Sample message for iOS endpoints\", \"title\":\"Hello world\"} }" }
As seen here APNS attributes seem to at least partly work if added within the GCM message like content_available in this case or badge.
I am sending push notifications from my server (to a firebase token and not to a topic). I do not differentiate between the platforms, the server just sends the JSON via RestTemplate (Spring Boot App).
If I prepare it for Android, it works, but it does not for for iOS. But if I prepare it for iOS, it does not work for Android.
The case is: I want the notification and the background process (It should display the notification in any case foreground/background/killed and it should take key-value pairs from the data payload).
The problem is: If I use notification in my JSON, the notification would be displayed on iOS and on Android but just the iOS can handle the payload (in foreground/background/killed state). If I remove the notification tag in JSON, then everything works fine (Android and iOS receives the payload in all states, but the iOS does not display the notification).
In Android you can build the notification client side (like me), but in iOS its not possible.
So, how can I send a FCM (JSON) with a firebase-token and it is platform-independent? Both can handle it properly, both receive the payload and displays the message and payload should be handled in every state.
This works on android and displays the message (built client side) but does not work for iOS
{
"content_available": true,
"data":{
"action":"bla",
"value":"true",
"id":"111111"
},
"android":{
"priority":"high"
},
"apns":{
"headers":{
"apns-priority":"10"
}
},
"to":"<MY_FCM_TOKEN>"
}
This displays the FCM for android and iOS, but handles the payload just on iOS
{
"notification":{
"sound":"default",
"title":"Test Title",
"body":"Message of FCM"
},
"content_available": true,
"data":{
"action":"bla",
"value":"true",
"id":"111111"
},
"android":{
"priority":"high"
},
"apns":{
"headers":{
"apns-priority":"10"
}
},
"to":"<MY_FCM_TOKEN>"
}
Or is it possible to declare the notification-tag just for iOS?
Or is it possible to create notifications also client side in iOS when a payload receives?
Before sending a notification on the Server side I am checking whether the the platfomr is iOS or Android by using google's method:
https://iid.googleapis.com/iid/info/IID_TOKEN
Which on success returns a JSON with a 'platform' parameter.
You can find more info here
We are using firebase to send notifications to both Android and IOS devices from server and we are using legacy FCM to send notifications.
But when our app is backgrounded notification is handled by system itself and thus we couldn't handle it by app. So we need to add data to notification to handle the notification by application itself on android side.
But due to we also have ios devices we couldn't remove notification from the pattern.
Is there any way to send data to Android devices and notification to IOS devices?
Also you may find the pattern that I mentioned at below.
{
{
"registration_ids":[
],
"content_available":true,
"priority":"high",
"data":{
"title":"",
"text":"",
"badge": 1,
"sound": "default"
},
"notification":{
"title":"",
"body":"",
"badge": 1,
"sound": "default"
}
}
You will have to map the FCM Registration ID with the OS Type and store it somehow. Now when you are sending the notifications, based on the OS Type, you will change the body structure for the notifications.
