So iOS 12 introduced Provisional Authorization for Quiet Notifications that could be seen in Notification Center but not on the Lock screen. It has very cool advantage - you don't need user's approval to send one.
Several articles (smashingmagazine.com, gadgethacks.com, etc.) claim that iOS app will be able to set it's badge if received Provisional Authorization.
Is it really possible to set app badge when app is Provisionally Authorized?
I request authorization using code below:
[[UNUserNotificationCenter currentNotificationCenter]
requestAuthorizationWithOptions:UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionProvisional
completionHandler:^(BOOL granted, NSError *_Nullable error) {
if (granted) {
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
}];
I receive token at didRegisterForRemoteNotificationsWithDeviceToken: that could be used to send Push Notification. When I send Push Notification with a payload {"aps":{"alert":"Testing..","badge":1}} I see it in Notification Center but app doesn't get badged.
I tried setting badge using UIApplication.sharedApplication.applicationIconBadgeNumber = 1; but it didn't work as well. It works though if I request regular authorization without providing UNAuthorizationOptionProvisional option.
Same issue here.
It seems, that app badges are off by default for provisional authorization. I couldn't find anything about it in the documentation.
But you can see it in the apps notification settings. The "Badges" switch is off by default:
App badges are also off for provisional notifications in iOS 15.
So this doesn't do anything, unless you go to System Settings and toggle the badges switch.
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .provisional]) { granted, error in
if granted {
DispatchQueue.main.async {
UIApplication.shared.applicationIconBadgeNumber = Int.random(in: 1...1000)
}
}
}
Anyone know a workaround?

I have a Flutter application using the firebase-messaging plugin for push notifications.
I register firebase like normal on the client, and I send the fcmToken to the server.
Notifications are created via a python server using aiofcm (which uses firebase's XMPP api). They're created like this:
message = aiofcm.Message(
device_token = t2,
notification = {
"title":notification_title,
"body":notification_body,
"sound":"default",
"tag":link
},
data = {
"click_action": "FLUTTER_NOTIFICATION_CLICK"
},
priority=aiofcm.PRIORITY_HIGH
)
await fcm.send_message(message)
On iOS, notifications pop-up at the top of the screen.
On Android, only the icon shows up in the notification tray - not any of the notification content. This is tested on a Pixel 3 and a OnePlus 6, both running Android P.
Ideally, I would like the notification to be "heads-up" style like this:
Before I was able to accomplish this using data messages and creating the notification programmatically in native android, however I would like to avoid that if possible since data messages don't get delivered on Android if the app is terminated.
To Get heads-up - Notification - Kindly set "alert: true"
Example :
notification = {
"title":notification_title,
"body":notification_body,
"sound":"default",
"alert" : true
"tag":link
},
For heads up notification you will need to use flutter_local_notifications Plugin. It is even recommended in FlutterFire official documentation for notification to show notification in foreground (background notification also supported ofcourse!) and it shows heads up notification by default.
You should check out the firebase.flutter.dev docs it shows how to do this easily with the help of flutter_local_notifiation
you can use background fetch and local notification package for background app running.
I'm having an issue with FCM on flutter. I have implemented messaging from my server so I'm storing my phone token for each user.
The thing is that when a user logs in for the very first time everything works properly, messages are being sent and user gets notified.
If I do not use the app during the weekend, on Monday I try to send a message by doing some actions on my app but messages are not being sent. I can see my token stored properly in my database.
I'm using firebase_messaging 2.1.0 for flutter.
This is how I get my token
_fireBaseMessaging.getToken().then((token){
_myPhoneToken = token;
});
1-I know token may change when:
App deletes Instance ID
App is restored on a new device
User uninstalls/reinstall the app
User clears app data
But none of this happens.
Any advice on how to handle this scenario? thanks in advance.
UPDATE
Provided you have setup the FCM sdk the right way (but you said that it works the fist time you install the app, so I guess so).
Provided that you are sure that the device_token you are using is the one of the device on which you are expecting to receive the notification (check if it's still the same), you should get on this device your notification quite soon if you use "priority" : "high".
{
"to" : "device_token",
"priority" : "high",
"notification" : {
"sound": "default",
"body" : "Test Notification body",
"title": "Test Notification title"
}
}
This method call
_firebaseMessaging.getToken().then((String token)
return always the new token even if it has been updated. So if you print this out on your device and you send a notification on this token without error, there's no reason why you should not get the token if the device has a valid internet connection active.
It's true that the device token can change during time. If you uninstall and reinstall the app, you can see the token will change and if you try to send a notification on the old one, you will get an error.
If instead the token will change during application lifetime, you can be notify on your server side by listening:
_firebaseMessaging.onTokenRefresh.listen((newToken) {
_fcm_token = newToken;
// send the new fcm to your server
});
So first of all I suggest you to be able to send a notification to a device with Postman. Check if the token you are using is still the one on the device. Then you can try to uninstall and reinstall the application and try to use the old token. You will get an error. Then try to send to the new one, and you should get your notification.
Then wait for some days and try again, check if the token has changed or not and if it's not changed you should be able to send the notification without problems with the same token.
Also be aware that data message on Android if the app is terminated are still not supported.
Some networks/router/mobile can cut the connection between firebase library and firebase server due to inactivity (5min without message). This cut may be detected by the library up to 30min (FCM heatbeat interval).
These are some links discussing this issue:
https://github.com/firebase/quickstart-android/issues/307
Android: Delay in Receiving message in FCM(onMessageReceived)
I contacted firebase support but they told that since the issue is caused by external part they cannot fix it (I suggest decreasing heartbeat interval ...)
I fixed it in android using an interval job which apply these instructions:
context.sendBroadcast(new Intent("com.google.android.intent.action.GTALK_HEARTBEAT"));
context.sendBroadcast(new Intent("com.google.android.intent.action.MCS_HEARTBEAT"));
You may write this specific code for Android side and should find something similar for ios side.
I'm using react-native-firebase with firebase-messaging to implement push notifications.
While I can send push notifications to everyone, I'm unable to send them to individuals. To my knowledge, all I need is the FCM Registration Token which I retrieve by following the documentation
firebase.messaging().getToken()
.then(fcmToken => {
if (fcmToken) {
console.log("fcm token", fcmToken);
} else {
console.log("fcm token", "null");
}
});
The token I receive is a plausible token, but when I copy that token from the logs into the firebase console and try to send it to a single device, nothing is received. (If I push to a user segment, it's received by all devices with the app installed).
As I can not test for iOS, this might or might not also be a problem on iOS.
In my build.gradle file, the firebase relevant libraries are included like so:
compile(project(':react-native-firebase')) {
transitive = false
}
implementation "com.google.android.gms:play-services-base:15.0.1"
implementation "com.google.firebase:firebase-core:16.0.1"
implementation 'com.google.firebase:firebase-auth:16.0.2'
implementation "com.google.firebase:firebase-messaging:17.1.0"
In the MainApplication.java file I add them to the list of ReactPackages.
new RNGoogleSigninPackage(),
new RNFirebasePackage(),
new RNFirebaseMessagingPackage(),
new RNFirebaseAuthPackage()
My AndroidManifest does not have any Firebase relevant changes as I discovered that push notifications were working even without them. (While trying to implement push notifications I noticed that all phones were receiving them except the one I was actively working on - so I rolled back the code.)
edit: I managed to receive one single device notification. Without any changes, it was suddenly working exactly once. Now it doesn't work anymore.
I have searched the web on my question but did not find anyone answering it. This looks weird as I am sure other people face similar issue.
At the moment my app is receiving push notification fine. I have a chat module where user can speak and whenever a new message is being sent, the other phone receive a push notification to update the chat.
You could say no issue there, but the problem is when the user is out of the application: he is still receiving those notifications showing a banner on the screen, and I want to dis-activate this. Basically I want push notification without alerts to the user. Is there a way to do that?
Thanks
Just leave the sound property of your push notification payload empty, omit the alert/text property and add "content-available":1 and your notification will be silent. This is often referred to as silent push notification or "push-to-sync".
See documentation here:
For a push notification to trigger a download operation, the
notification’s payload must include the content-available key with its
value set to 1. When that key is present, the system wakes the app in
the background (or launches it into the background) and calls the app
delegate’s
application:didReceiveRemoteNotification:fetchCompletionHandler:
method. Your implementation of that method should download the
relevant content and integrate it into your app
So your payload should least look like this:
{
"aps" : {
"content-available" : 1,
"sound" : ""
},
"chat-message" : "Hello World!"
}
I'm having as issue with Push Notification to iOS8 device. Everything works fine, but the push is not ringing, only appears on the screen.
I am sending normal pushes via dashboard, in which sound is enabled by default. I tested on iPhone4 (iOS 7.1.2), iPhone5 (iOS 7.0.4), it works fine, but there is no sound on iPhone with iOS 8.
Thanks
edit:
1) We have already modified our code to handle changes push notification registration for ios8. Below is the code snippet:
// Register for Push Notitications, if running iOS 8
if ([application respondsToSelector:#selector(registerUserNotificationSettings:)]) {
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge |
UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
} else {
// Register for Push Notifications before iOS 8
[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}
2) Changing any and all configuration settings doesn't helped either, nor does restarting the device.
Seems like you need this in the request JSON: "sound": "default". Blank used to work, but now needs "default" to use the default sound.
The push register method is changed in iOS 8.Check following possibilities..
1)Check whether you register push notification with sound as this link.
2)Another possibility is sound can be switched off in notification centre.Check in settings-->notification centre-->click on the app and enable sound.
