How can I track the opening of app by clicking on a notification?

Hi, how can i detect that user clicked on notification?

I need that when I click on a notification, a screen will open depending on the data in the notification.

@ValdZX @mirzemehdi Please, any help?

I think this is more about adding deeplink support to library. But I am still checking my options

This is implemented in library version 0.5.0.

This is how you can use it:

Detecting notification click and get payload data

NotifierManager.addListener(object : NotifierManager.Listener {
    override fun onNotificationClicked(data: PayloadData) {
        super.onNotificationClicked(data)
        println("Notification clicked, Notification payloadData: $data")
    }
}) 

You need to call below platform-specific functions in order to receive payload data properly.

Android

Call NotifierManager.onCreateOrOnNewIntent(intent) on launcher Activity's onCreate and onNewIntent methods.

override fun onCreate(savedInstanceState: Bundle?) {
   super.onCreate(savedInstanceState)
      NotifierManager.onCreateOrOnNewIntent(intent)
      ...
    }

    override fun onNewIntent(intent: Intent?) {
        super.onNewIntent(intent)
        NotifierManager.onCreateOrOnNewIntent(intent)
    }

iOS

Call NotifierManager.onApplicationDidReceiveRemoteNotification(userInfo: userInfo) on application's didReceiveRemoteNotification method.

 func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) async -> UIBackgroundFetchResult {
      NotifierManager.shared.onApplicationDidReceiveRemoteNotification(userInfo: userInfo)
      return UIBackgroundFetchResult.newData
 }

Please, let me know if there is any issue

On my side (ios impl) onNotificationClicked callback not get called when app is in background. I have followed all the conf steps and tried to use UNUserNotificationCenterDelegate too, but without luck. Can you confirm that on your side package callback is triggered when app is in background?

[mirzemehdi]

@emanuelecastelli yes, when I click notification I get listener callback.

1) Make sure you enabled remote-notificaiton in backgorund modes in XCode. 2) You added this part in ios part

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) async -> UIBackgroundFetchResult {
        NotifierManager.shared.onApplicationDidReceiveRemoteNotification(userInfo: userInfo)
        return UIBackgroundFetchResult.newData
    }

i have done everything. When app is in foreground, i din't see the notification, but i get every log that i do in native and in cross. When app is in background, i see the notification at the top, i tap on it but no log is printed out (nor from native nor from cross). The debugger too not get called in xcode (breakpoint set in didReceiveRemoteNotification). App simply returns in foreground.

@mirzemehdi can you provide json body that you use for test push notifications? I'm using something like that, playing with apns props, but no way :(

{
  "message": {
    "token": ".......",
     "notification": {
      "title": "title",
      "body": "Notification from FCM"
    },
    "apns": {

        "headers": {

        },
        "payload": {

        }
    }
  }
}

Ok, restoring FCM method swizzling resolve the issue: push notifications callbacks now runs correctly
