[firebase_messaging]: <background message handler never invoked with all ways> #12758

Closed HassanSharara closed 3 months ago

HassanSharara commented 3 months ago

Is there an existing issue for this?

Are you aware of the differences between iOS and Android background message handling?

Do you have an active Apple Developer account?

Are you using a physical iOS device to test background messages?

Have you enabled "Remote Notifications" & "Background Mode" (Checking options for "Background Processing" & "Remote Notifications") in your app's Xcode project?

yes u already enabled these options

Have you created an APNs key in your Apple Developer account & uploaded this APNs key to your Firebase console?

Screenshot (1)

Have you disabled method swizzling for Firebase in your app?

Have you used the 'Console' application on your macOS device to check if the iOS device's system is throttling your background messages?

Additional context and comments

i believe that this error related to firebase sdk or apple updates and i tried countless ways to solve this

and i think this error message is related to UserNotificationsServer error 14:16:25.731358+0300 SpringBoard No data found at /var/mobile/Library/UserNotifications/AACFA2BF-DA41-4321-A69D-5B126E5AAA31/Categories.plist

Please set FirebaseAppDelegateProxyEnabled to YES in your info.plist and try again.

i tried that before still not working

russellwheatley commented 3 months ago

Hi @HassanSharara - what is the issue exactly? I have tested and it works fine on my apple device.

HassanSharara commented 3 months ago

Hi @HassanSharara - what is the issue exactly? I have tested and it works fine on my apple device.

the exactly issue is that FirebaseMessaging.onBackgroundMessage Handler never invoked by any way and i need to call listen to Channel Method Manually to replace this method functionality

EdsonMello-code commented 3 months ago

I have exactly the same problem, the notifications arrive even in the background but onBackgroundMessage is never called in any case.

EdsonMello-code commented 3 months ago

Any solution? because I tried everything. This is my send payload:

{
  "message": {
    "token": "token",

            "notification": {
      "title": "Notification",
      "body": "Hello World!"
    },

    "android": {
      "priority": "high"
    },
    "apns": {
      "payload": {
        "aps": {
          "content-available": 1,
                    "mutable-content": 1
        }
      },
      "headers": {

        "apns-priority": "5",

      }
    }
  }
}
ivanluizjr commented 3 months ago

I'm having the same problem, I can't find a solution, I'm going to wait for the answer to see if I can solve it here too, as I'm facing the same case as above.

TarekkMA commented 3 months ago

@HassanSharara, Can you post a complete console output.

To check the status of your push notification, please follow the steps below.

  1. Open the Console app on your Mac
  2. Select your iPhone from the devices list on the left hand side
  3. Filter messages by typing in your Bundle ID (e.g. The Firebase Messaging example app bundle ID is 'io.flutter.plugins.firebase.messaging') into the search box and pressing enter.
  4. Press the clear button to clean the history.
  5. Now send the message to your device
  6. Select all the rows on the logs & copy them, Cmd + C (not available on right-click menu)

I already Implement Native IOS Code to get passed this issue and now its working better than the firebase_messaging implementation cause my work need is to Listen to every income notification no matter if its has notification key payload or not and i wish that firebase team to fix this issue on the next versions of the plugin

Can you please give me the way to implement it too as I have the same problem

1- you need to create static MethodChannel in flutter 

  static const MethodChannel platformMethodChannel = MethodChannel('sharara_ios_background_messaging_handler');

2- secondly you need to initialize handler linked to this channel 

   static Future<void> initBackgroundMessagingHandlerListener()async{
    royalPlatformBackgroundMessagingHandler.setMethodCallHandler((call)async{
      if ( call.method == "ios_messaging"){
        return await onIosBackgroundMessaging(call.arguments);
      }
    });
  }

3 - you need to call initBackgroundMessagingHandlerListener on after configuring firebase

4- generating remote message from native ios call 

   static Future<dynamic> onIosBackgroundMessaging(final dynamic userInfo)async{
    if(userInfo is! Map)return;
    final RemoteMessage? remoteMessage = Constans.tryCatch<RemoteMessage>(() =>  
    RemoteMessage.fromMap(userInfo.cast()));
    if(remoteMessage == null)return;
    return await _handleBackgroundNotification(remoteMessage);
  }

6- Now we need to setup flutterChannel on native Ios Code inside your AppDelegate define an object of flutterMethodChannel

  var flutterChannel :FlutterMethodChannel

7- initialize this flutterChannel with the same name as MethodChannel was on flutter ('sharara_ios_background_messaging_handler')

example :

   if flutterChannel == nil {
          let flutterViewController:FlutterViewController
          = window?.rootViewController as! FlutterViewController
          flutterChannel  = FlutterMethodChannel(name: "sharara_ios_background_messaging_handler",
              binaryMessenger:flutterViewController.binaryMessenger
          )
      }

8- override this func on your AppDelegate example:

override  func application(
    _ application: UIApplication,
    didReceiveRemoteNotification userInfo: [AnyHashable : Any],
    fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void
) {
 if flutterChannel != nil {
      flutterChannel!.invokeMethod("ios_messaging",arguments:userInfo) { _ in
         /// you can implement your code here to call whatever you want after background handler end
          completionHandler(UIBackgroundFetchResult.newData)
      }
  } else {
      completionHandler(UIBackgroundFetchResult.noData)
  }
}

9 - congratulations everything is done

I already Implement Native IOS Code to get passed this issue and now its working better than the firebase_messaging implementation cause my work need is to Listen to every income notification no matter if its has notification key payload or not and i wish that firebase team to fix this issue on the next versions of the plugin

Can you please give me the way to implement it too as I have the same problem

1- you need to create static MethodChannel in flutter

  static const MethodChannel platformMethodChannel = MethodChannel('sharara_ios_background_messaging_handler');

2- secondly you need to initialize handler linked to this channel

 static Future<void> initBackgroundMessagingHandlerListener()async{
  royalPlatformBackgroundMessagingHandler.setMethodCallHandler((call)async{
    if ( call.method == "ios_messaging"){
      return await onIosBackgroundMessaging(call.arguments);
    }
  });
}

3 - you need to call initBackgroundMessagingHandlerListener on after configuring firebase 4- generating remote message from native ios call

 static Future<dynamic> onIosBackgroundMessaging(final dynamic userInfo)async{
  if(userInfo is! Map)return;
  final RemoteMessage? remoteMessage = Constans.tryCatch<RemoteMessage>(() =>  
  RemoteMessage.fromMap(userInfo.cast()));
  if(remoteMessage == null)return;
  return await _handleBackgroundNotification(remoteMessage);
}

6- Now we need to setup flutterChannel on native Ios Code inside your AppDelegate define an object of flutterMethodChannel

var flutterChannel :FlutterMethodChannel

7- initialize this flutterChannel with the same name as MethodChannel was on flutter ('sharara_ios_background_messaging_handler') example :

  if flutterChannel == nil {
         let flutterViewController:FlutterViewController
         = window?.rootViewController as! FlutterViewController
         flutterChannel  = FlutterMethodChannel(name: "sharara_ios_background_messaging_handler",
             binaryMessenger:flutterViewController.binaryMessenger
         )
     }

8- override this func on your AppDelegate example:

override  func application(
    _ application: UIApplication,
    didReceiveRemoteNotification userInfo: [AnyHashable : Any],
    fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void
) {
 if flutterChannel != nil {
      flutterChannel!.invokeMethod("ios_messaging",arguments:userInfo) { _ in
         /// you can implement your code here to call whatever you want after background handler end
          completionHandler(UIBackgroundFetchResult.newData)
      }
  } else {
      completionHandler(UIBackgroundFetchResult.noData)
  }
}

You are Welcome

It arrives in the background, but testing it better when the app is closed in release it calls the code in the background only when I open the app again. But this is better than it was before when it wasn't even possible

HassanSharara commented 3 months ago

This the way that you could invoke your custom handler when receive a message but not the way to escape from ios throttle system You need to implement strategy to schedule your background task to get what you want or there is another violate method and also keep in mind that debug mode on real device will be dismissed when u close the app and also rhe simulator will not probably work so you need to test that on Apple store with test fly

You are correct, it was throwing an exception and not completing the action

throwing an exception because of 

let flutterViewController:FlutterViewController
         = window?.rootViewController as! FlutterViewController

change as! to as?

cause when the app is terminated or there is no screen or ui to show the window object would be nil ( or null ) so it will not work if you want to use this implementation even on app is terminated you need run flutter engine on background i think if firebase team did not solve this i will build package to receive all data income from APS or firebase notifications
