Question

I have a Webview and for example : string url = "https://www.google.com"; UrlLoad(url); Show the Google in my App,

ok,If I received a notification and Push that, the Webview will Change page.

Just Like string url = Notification's body;

I'm sorry ,my English is not good.

Thanks.

ps. I'm use Xamarin

This is FCM Receive

[Service]

   [IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]   
   class Firebasemessaging : FirebaseMessagingService
   {
    public override void OnMessageReceived(RemoteMessage message)
    {
        this.SendNotification(message.GetNotification().Body);
        Notification notifi = new 
    Notification(Resource.Drawable.pika,"Handbim");

    }

    private void SendNotification(string body)
    {
        var intent = new Intent(this, typeof(MainActivity));
        intent.AddFlags(ActivityFlags.ClearTop);
        var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
        var defaultsoundUri = RingtoneManager.GetDefaultUri(RingtoneType.Notification);
        var notif = new NotificationCompat.Builder(this)
            .SetContentTitle("handbim")
            .SetContentText(body)
            .SetAutoCancel(true)
            .SetSound(defaultsoundUri)
            .SetContentIntent(pendingIntent);

      var notificationManager = NotificationManager.FromContext(this);
        notificationManager.Notify(0,notif.Build());

    }
}

Please use OnNewIntent to achieve your goal.

1) Add LaunchMode =Android.Content.PM.LaunchMode.SingleTop in your MainActivity's attribute, like this:

[Activity(Label = "StartStopService", MainLauncher = true,LaunchMode =Android.Content.PM.LaunchMode.SingleTop)]

2) In your SendNotification method, add this line:

 intent.PutExtra("url", body);

So the body will be passed to your OnNewIntent method by intent.

3) Override OnNewIntent method in your MaintActivity, like this:

protected override void OnNewIntent(Intent intent)
{
    base.OnNewIntent(intent);

    string str = intent.GetStringExtra("url");
    Toast.MakeText(this, str, ToastLength.Short).Show();
    web_view.LoadUrl(str);
}

Note:

web_view is global variables
