  Hi @slayer35,

  I am not sure this is correct way or not but it's working for me

  Xamarin.iOS:

  App.Current.MainPage = new PageName(); put in DidReceiveRemoteNotification

  Example:

  AppliedJobDetails is the page name I mentioned

    public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, 
       Action<UIBackgroundFetchResult> completionHandler)
       {
  
         try
           {
             UIApplication.SharedApplication.ApplicationIconBadgeNumber = 0;
  
             NSDictionary aps = userInfo.ObjectForKey(new NSString("aps")) as NSDictionary;
             var notificationTitle = (aps[new NSString("title")] as NSString).ToString();
             var notificationMessage = (aps[new NSString("job_id")] as NSString).ToString();
             var NotificationId = (aps[new NSString("notification_id")] as NSString).ToString();
  
            if (UIApplication.SharedApplication.ApplicationState.Equals(UIApplicationState.Active))
            {
                 //App is in foreground. Act on it.
            }
            else
            {                   
                 App.Current.MainPage = new AppliedJobDetails(null, notificationMessage, NotificationId);
            }
        }
        catch (Exception ex)
        {
          //LogInfo.ReportErrorInfo(ex.Message, ex.StackTrace, "AppDelegate-DidReceiveRemoteNotification");
  
        }
     }

  Xamarin.Android:

  AppGcmListenerService.cs

  Below I passed job I'd, NotificationId parameters I mean push notification data to MainActivity.cs using PutExtra

            var intent = new Intent(this, typeof(MainActivity));
        intent.PutExtra("JobID", jobId); // Passed parameters to MainActivity.cs
        intent.PutExtra("NotificationId", NotificationId);
        intent.AddFlags(ActivityFlags.ClearTop);
  
       Random random = new Random();
       int pushCount = random.Next(9999 - 1000) + 1000; //for multiplepushnotifications
  
      intent.AddFlags(ActivityFlags.ClearTop);
      var pendingIntent = PendingIntent.GetActivity(this, pushCount, intent, PendingIntentFlags.Immutable);
  
          var notificationBuilder = new Notification.Builder(this)
          .SetSmallIcon(Resource.Drawable.OneIcon)
          .SetContentTitle(NotificationTitle)
          .SetContentText(NotificationMessage)
          .SetAutoCancel(true)
          .SetDefaults(NotificationDefaults.Sound)
          .SetContentIntent(pendingIntent);
  
     var notificationManager = (NotificationManager)GetSystemService(Context.NotificationService);
     notificationManager.Notify(pushCount, notificationBuilder.Build());
  

  MainActivity.cs

  Now Accessing those data in MainActivity.cs using GetStringExtra and passed one boolean value to the App.cs based on that boolean value I shall navigating the pages

          string JobId = Intent.GetStringExtra("JobID");
          string NotificationId = Intent.GetStringExtra("NotificationId");
          if (JobId == null || NotificationId == null)
          {
              LoadApplication(new App(false));
          }
          else
          {
              App.isNotified = JobId;
              App.isNotifiedId = NotificationId;
  
              LoadApplication(new App(true));
          }
  

  App.cs:

  Here accessing that boolean value and written some conditions

     public class App : Application
     {
      public static string isNotified;
      public static string isNotifiedId;
      public bool navigating;
             public bool  IsNotified;
  
      public App(bool shallNavigate)
      {   
          navigating = shallNavigate;  
      }
  
  
      protected override void OnStart()
      {
          OnAppStart();// Handle when your app starts
      }
  
      protected override void OnSleep()
      {
          // Handle when your app sleeps
      }
  
      protected override void OnResume()
      {

  @BalaRaju

  As you are showing/writing navigation in else block of UIApplicationState.Active , I wonder how it going to work, why because notifications tap events firing somewhere else.
  I am using Xamarin.iOS, and notification tap event here firing.

   public class CustomUNUserNotificationCenterDelegate : UNUserNotificationCenterDelegate
      {
          public override void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
          {
           **   // Here you handle the user taps**
              completionHandler();     
          }
          public override void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
          {
              completionHandler(UNNotificationPresentationOptions.Alert | UNNotificationPresentationOptions.Sound | UNNotificationPresentationOptions.Badge);
          }
      } 
  

  However I am getting notifications data here. but I dont have idea to navigate to specific page.
  Please suggest me if you people have better idea.

  Thank you

  So I want to have a notification open a new page, so the user can view the full message.
  It works great with Xamarin.Android, you use the Notification.Builder(), and start a new Intent. voila

  But with Xamarin.iOS, if the app is open , I have no luck.
  Trying App.Current.MainPage.Navigation.PushModalAsync(new MyPage()) and it does nothing , it just stays at the current screen on the app

  Any ideas?

  @VenkataSwamy, thanks for your solution. It works well.
  Did you ever do saving the push notification in a local database?

  __in android side you can use this way_

  first in MainActivity
  LaunchMode = LaunchMode.SingleTop_

  and than_

  protected override void OnNewIntent(Intent intent)
  {
  if (intent != null)
  {
  string NotificationId = Intent.GetStringExtra("NotificationId");
  if (NotificationId != null)
  {
  App.IsNotified = true;
  App.NotifiedId = NotificationId;

                  Page currentPage = App.Current.MainPage.Navigation.NavigationStack.LastOrDefault();
                  var content = currentPage.FindByName<ContentView>("cvContentPlaceHolder");
                  var notificationsSegmentedBarPage = new NotificationsSegmentedBarPage(Convert.ToInt32(App.NotifiedId));
                  content.Content = notificationsSegmentedBarPage.Content;
              }
          }
      }

  Hi @VenkataSwamy I am trying to open a content page when taps the notification.

  What is AppGcmListenerService.cs? Is that invoke when we tap a notification? What are jobId and NotificationId? Is this work with FCM?

  Can you help me to complete this implementation? I have started a new thread for this.
