How to open downloaded file in xamarin forms?

In my Xamarin forms, I download a file in the Android App using Web client. It saved in the local folder. This will mention using the android notification as below code

            webClient.DownloadFile(filePath, localPath);
            Notification.Builder builder = new Notification.Builder(Android.App.Application.Context)
.SetContentTitle("Download Successfully")
.SetContentText("Click here to open")
.SetSmallIcon(Resource.Drawable.abc_btn_colored_material);
            Notification notification = builder.Build();
            NotificationManager notificationManager =
Android.App.Application.Context.GetSystemService(Context.NotificationService) as NotificationManager;
            const int notificationId = 0;
            notificationManager.Notify(notificationId, notification);

I want to open the downloaded file from the notification. How could i do that. I am new to the Xamarin. Please Suggest a solution.

I use this

var docSaved = await DisplayActionSheet("Saved", "Open", "Ok", "File was successfull);
   switch (docSaved)
   {
         case "Open":
         {
             Device.OpenUri(new Uri(Your_FilePath));
             break;
         }
         case "Ok":
         {
            break;
         }                   
   }

For your notification you can create a PendingIntent with an Intent, which has Action View on the file. This would look something like:

var mimeTypeMap = MimeTypeMap.Singleton;
var mimeType = mimeTypeMap.GetMimeTypeFromExtension(System.IO.Path.GetExtension(filePath));

var intent = new Intent();
intent.SetAction(Intent.ActionView);
intent.SetDataAndType(Android.Net.Uri.Parse(filePath), mimeType);

var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);

Then you set that Intent in your Notification builder:

notification.SetContentIntent(pendingIntent);

Now, the filePath you give the Intent must be somewhere that is accessible from all applications on Android, otherwise opening it will fail. So when you save the file, save it to External Storage in a public place.
