OnNotificationOpened not hit when app killed on Android

[cvchris]

🐛 Bug Report

The notification comes through even when app is killed, but when clicking on notification, it doesn't run OnNotificationOpened method (which is on MainApplication.cs) and the body is:

CrossFirebasePushNotification.Current.OnNotificationOpened += (s, p) =>
            {
                string tag = "aimmsapp";

                Android.Util.Log.Info(tag, "Opened");
                System.Diagnostics.Debug.WriteLine("Opened");
                foreach (var data in p.Data)
                {
                    System.Diagnostics.Debug.WriteLine($"{data.Key} : {data.Value}");
                }


            };

I can see from the device logs that this method is not ran, but when the device is in background, it runs when I click the notification.

The payload sent is:

var pushData = new
                {
                    to = deviceToken,
                    content_available = true,
                    data = new
                    {
                        body = message, 
                        payload = new
                        {
                            android = new
                            {
                                title = title,
                                alert = message,
                                sound = "default",
                                vibrate = true,
                                icon = "appicon"
                            },
                        },
                        extData = extData
                    },
                    priority = "high"
                };

Expected behavior

It should ran OnNotificationOpened method on MainApplication when I click the notification.

Reproduction steps

Kill the app, and send notification. OnNotificationOpened method should not ran when clicking the notification.

Hello, have you found a solution to this ?

If you have a splash Activity which is set to MainLauncher = true, Update your Activity like below.
`public class SplashActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
FirebasePushNotificationManager.ProcessIntent(this,Intent);
}
protected override void OnNewIntent(Intent intent)
{
base.OnNewIntent(intent);
FirebasePushNotificationManager.ProcessIntent(this,intent);
}
protected override void OnResume()
{
base.OnResume();
Task startupWork = new Task(() => { SimulateStartup(); });
startupWork.Start();
}

    async void SimulateStartup()
    {
        await Task.Delay(0000); // Simulate a bit of startup work.
        StartActivity(new Intent(Application.Context, typeof(MainActivity)));
    }
}`

Hello i solved this by moving the event set to the Application constructor instead of the OnStart() method described in the sample

  public App()
    {
	InitializeComponent();
        MainPage = new Views.StartupPage();
        CrossFirebasePushNotification.Current.OnNotificationReceived += async (s, p) =>
			{
				await Task.Run(() =>
				  { 
						  FirebaseClient.Model.Notification Notification = JsonConvert.DeserializeObject<FirebaseClient.Model.Notification>(p.Data["Notification"].ToString());
						  NotificationsViewModel.Default.OnNewNotification(Notification);
					  
				  });
			};
}

it seems that the event is launched too early for the app to catch even though the enableDelayedResponse parameter is set to true

LoadApplication(new App());
FirebasePushNotificationManager.ProcessIntent(this, Intent);

This solved my problem and when user click the notification the appropriate page will appear but only on version 3.3.10 updating to the latest version 3.4.1 broke it again
