I'm sending a tile update to my app users. After the tile update I would like to automatically direct the user to the new updated page once he clicks the new tile. Is there any way I can achieve this?
I can't pull the server anymore because it's a fire & forget mechanism.
With toast notifications I can use the following message in my notification:
<wp:Param>/Views/MyPage.xaml</wp:Param>
But that doesn't seem to work with my FlipTile update.
Im not quite sure if this is what you are looking for, but can you just replace the Tile once the app is loaded? Somewhat like this:
/// <summary>
/// Creates or replaces a tile with a Title and a parameter
/// </summary>
public void replaceTile()
{
//ShellTile TileToFind = ShellTile.ActiveTiles.First();
string tileTitle = "Title of the Tile";
//You might want to use your Parameter from the toast here as the PageName
ShellTile TileToFind = FindTile( "/PageName.xaml?parameter" );
StandardTileData NewTileData = new StandardTileData
{
Title = tileTitle,
BackgroundImage = new Uri( "/Resources/tile_icon.png", UriKind.Relative ),
Count = 0,
BackTitle = "",
//BackBackgroundImage = new Uri("/Resources/appicon_large.png", UriKind.Relative),
BackBackgroundImage = new Uri( "", UriKind.Relative ),
BackContent = ""
};
// Application should always be found, since it is always the first tile (even if not on homescreen)
if ( TileToFind == null )
{
// Update the Application Tile with the NewTileData
//TileToFind.Update( NewTileData );
//Or replace an existing (second) tile with the new, updated Tile
//ShellTile alreadyExistingTile = FindTile( "/PageName.xaml?parameter" );
//if ( alreadyExistingTile != null )
//{
// alreadyExistingTile.Delete();
//}
ShellTile.Create( new Uri( "/PageName.xaml?parameter=" + newParameter, UriKind.Relative ), NewTileData );
}
else
{
TileToFind.Update( NewTileData );
}}

I have UWP Windows application, developed under the Xamarin.forms. I have implemented the Toast notifications but I am facing the issue with this. In some Windows 10 systems, it is working and showing the toast notification properly, but in some of the Windows 10 systems (even having the same Windows 10 OS update) it is not working.
Below first code snippets that I have implemented in the Native UWP.
string msg = "Toast Notification Header";
string subMsg = "Toast Notification Title";
var toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02);
var toastTextElements = toastXml.GetElementsByTagName("text");
toastTextElements[0].AppendChild(toastXml.CreateTextNode(msg));
toastTextElements[1].AppendChild(toastXml.CreateTextNode(subMsg));
//To play the custom sound
var toastNode = toastXml.SelectSingleNode("/toast");
var audio = toastXml.CreateElement("audio");
audio.SetAttribute("src", "ms-appx:///Assets/incoming_message.wav");
audio.SetAttribute("loop", "false");
toastNode.AppendChild(audio);
var toast = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier().Show(toast);
Below second code snippets that I have implemented in the Native UWP.
// "With Microsoft.Toolkit.Uwp.Notifications"
// Construct the toast content
ToastContent toastContent = new ToastContent()
{
Visual = new ToastVisual()
{
BindingGeneric = new ToastBindingGeneric()
{
Children =
{
new AdaptiveText()
{
Text = "Toast Notification Header"
},
new AdaptiveText()
{
Text = "Toast Notification Content"
}
}
}
}
};
bool supportsCustomAudio = true;
// If we're running on Desktop before Version 1511, do NOT include custom audio
// since it was not supported until Version 1511, and would result in a silent toast.
if (AnalyticsInfo.VersionInfo.DeviceFamily.Equals("Windows.Desktop")
&& !ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 2))
{
supportsCustomAudio = false;
}
if (supportsCustomAudio)
{
toastContent.Audio = new ToastAudio()
{
Src = new Uri("ms-appx:///Assets/incoming_message.wav")
};
}
// And create the toast notification
ToastNotification notification = new ToastNotification(toastContent.GetXml());
// And then send the toast
ToastNotificationManager.CreateToastNotifier().Show(notification);
Above code snips showing the Toast notification in some Windows 10 system and not working in some other Windows 10 system.
Kindly guide me on this. Thanks in advance.

Please follow these steps to add toast notification in UWP Project.
Step 1:- Create a new UWP project.
Step 2:- Go to the code-behind and add the namespace.
using Windows.UI.Notifications;
using
NotificationsExtensions.Toasts;
Step 3:- I created a Toast Generic Template like the following code:
public static Windows.Data.Xml.Dom.XmlDocument CreateToast()
{
var xDoc = new XDocument(
new XElement("toast",
new XElement("visual",
new XElement("binding", new XAttribute("template", "ToastGeneric"),
new XElement("text", "C# Corner"),
new XElement("text", "Do you got MVP award?")
)
),// actions
new XElement("actions",
new XElement("action", new XAttribute("activationType", "background"),
new XAttribute("content", "Yes"), new XAttribute("arguments", "yes")),
new XElement("action", new XAttribute("activationType", "background"),
new XAttribute("content", "No"), new XAttribute("arguments", "no"))
)
)
);
var xmlDoc = new Windows.Data.Xml.Dom.XmlDocument();
xmlDoc.LoadXml(xDoc.ToString());
return xmlDoc;
}
Step 4:- Create a toast notification object using XML document.
var xmdock = CreateToast();
var toast = new ToastNotification(xmdock);
Next show the toast using ToastNotificationManager class.
var notifi = Windows.UI.Notifications.ToastNotificationManager.CreateToastNotifier();
notifi.Show(toast);
Step 5:- C# code-behind:
private void showToastBtn_Click(object sender, RoutedEventArgs e)
{
var xmdock = CreateToast();
var toast = new ToastNotification(xmdock);
var notifi = Windows.UI.Notifications.ToastNotificationManager.CreateToastNotifier();
notifi.Show(toast);
}
I hope the above code will be useful for you.
Thank you
i have xamarin forms app that support notification, i have done it in android with broadcast receiver now i have to do notification in ios ! , my service is depending on API REST so i want every 60 second ios app run HTTP request and get data then show it as notification, i searched for many days but i can't reach to my approach ?
if this is impossible can i use nuget or something like that in ios project only "in xamarin forms solution " or not ?
content = new UNMutableNotificationContent();
content.Title = "Notification Title";
content.Subtitle = "Notification Subtitle";
content.Body = "This is the message body of the notification.";
content.Badge = 1;
content.CategoryIdentifier = "message";
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(60, true);
var requestID = "sampleRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
// Do something with error...
}
});
Here is my code for generating a local notification on iOS
var alertsAllowed = false;
UNUserNotificationCenter.Current.GetNotificationSettings((settings) =>
{
alertsAllowed = (settings.AlertSetting == UNNotificationSetting.Enabled);
});
if (alertsAllowed)
{
var content = new UNMutableNotificationContent();
content.Title = "Incident Recorder";
content.Subtitle = "Not Synchronised";
content.Body = "There are one or more new incidents that have not been synchronised to the server.";
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(5, false);
var requestID = "sampleRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
Console.WriteLine(err.LocalizedFailureReason);
}
});
}
The first parameter in CreateTrigger is how long before the notification is generated. I notice you have 60 in yours. Also bear in mind a notification will not appear if your app is foregrounded.
UPDATE:
I've tried implementing this in an App.cs method called OpenCameraScanner (you would call this on click of a button on the page from which you want to scan):
App.cs
------------------------------------------------
public static ZXingScannerPage ScanPage;
public static ZXing.Result ScanResult;
public static async void OpenCameraScanner()
{
ScanPage = new ZXingScannerPage(customOverlay: customOverlay);
ScanPage.OnScanResult += (result) =>
{
ScanPage.IsScanning = false;
ScanResult = result;
Device.BeginInvokeOnMainThread(() =>
{
App.CurrentApp.CurrentPage.Navigation.PopModalAsync();
App.CurrentApp.CurrentPage.DisplayAlert("Scanned Barcode", result.Text, "OK");
});
};
var scanPage = new NavigationPage(ScanPage);
await App.CurrentApp.CurrentPage.Navigation.PushModalAsync(ScanPage);
}
However, when this method is called, the screen that opens is blank white, and you can't see the camera view behind it. Not sure why?
I'm using ZXing.Mobile in a Xamarin.Forms project (for iOS right now) for camera scanning functionality on an iPad.
Currently, I have it working great with the following 2 lines:
var scanner = new ZXing.Mobile.MobileBarcodeScanner();
var result = await scanner.Scan();
However, when the camera is open to scan, it takes up the entire iPad screen, which is really big.
Question: Is there a way to adjust the size of the camera overlay? (so that it's not full screen)
I see that the scanner.Scan() method takes an optional options parameter of type ZXing.Mobile.MobileBarcodeScanningOptions - I tried playing around with that, but the only possible relevant option there is a CameraResolutionSelector - but I'm having a really hard time finding any documentation on that.
There is a ZXing sample app that shows how to embed the ZXingScannerView and ZXingDefaultOverlay into a Xamarin.Form's Grid:
https://github.com/Redth/ZXing.Net.Mobile/blob/master/Samples/Forms/Core/CustomScanPage.cs
public CustomScanPage () : base ()
{
zxing = new ZXingScannerView
{
HorizontalOptions = LayoutOptions.FillAndExpand,
VerticalOptions = LayoutOptions.FillAndExpand,
AutomationId = "zxingScannerView",
};
zxing.OnScanResult += (result) =>
Device.BeginInvokeOnMainThread (async () => {
// Stop analysis until we navigate away so we don't keep reading barcodes
zxing.IsAnalyzing = false;
// Show an alert
await DisplayAlert ("Scanned Barcode", result.Text, "OK");
// Navigate away
await Navigation.PopAsync ();
});
overlay = new ZXingDefaultOverlay
{
TopText = "Hold your phone up to the barcode",
BottomText = "Scanning will happen automatically",
ShowFlashButton = zxing.HasTorch,
AutomationId = "zxingDefaultOverlay",
};
overlay.FlashButtonClicked += (sender, e) => {
zxing.IsTorchOn = !zxing.IsTorchOn;
};
var grid = new Grid
{
VerticalOptions = LayoutOptions.FillAndExpand,
HorizontalOptions = LayoutOptions.FillAndExpand,
};
grid.Children.Add(zxing);
grid.Children.Add(overlay);
// The root page of your application
Content = grid;
}
i want to set secondry tile in my app but i don't know where i put code of secondry tile because it show unhandled exception and my App does not run it back
var foundTile = ShellTile.ActiveTiles.FirstOrDefault(x => x.NavigationUri.ToString().Contains("DetailId=123"));
if (foundTile == null)
{
var secondaryTile = new StandardTileData
{
BackgroundImage = new Uri("Images/SecondaryTileFrontIcon.jpg", UriKind.Relative),
Title = "hiiiiiiii",
Count = null,
BackTitle = "",
BackContent = "byeeeee ",
BackBackgroundImage = new Uri("Images/ApplicationTileIcon.jpg", UriKind.Relative)
};
ShellTile.Create(new Uri("/Views/DetailsPage.xaml?DetailId=123", UriKind.Relative), secondaryTile);
}
Each tile is identified by the Uri supplied to ShellTile.Create. In your case, you're not creating a secondary tile, but checking if the same tile already exists, and if it's not, then you create it.
If you want more than one tile, you need to use different uri's for the ShellTile.Create call, typically with different query-string parameters/values.
And you obviously shouldn't make it dependant on the uri of completely unrelated tile.
In my app I want to display a simple string within a popup when the user clicks on an image. For this I added a Tap gesture listener to the image and within the handler I have the following code:
private void GestureListener_Tap( object sender, GestureEventArgs e )
{
var img = sender as Image;
if( img == null ) {
return;
}
Point pos = e.GetPosition( img );
string text = "I'm a popup!";
var popup = new Popup() {
Child = new Border() {
BorderBrush = new SolidColorBrush( Colors.LightGray ),
Child = new TextBlock() {
Text = text,
TextWrapping = TextWrapping.Wrap,
},
},
HorizontalAlignment = HorizontalAlignment.Stretch,
HorizontalOffset = pos.X,
VerticalOffset = pos.Y,
Visibility = Visibility.Visible,
};
popup.IsOpen = true;
Debug.WriteLine( "GestureListener_Tap: " + text );
}
The call to WriteLine prints in the debugger output window but the popup doesn't get displayed. What am I doing wrong here?
Thanks for your help!
I tried your code and the Popup is displayed. I think the problem for you is the Position for the Image relative to the Mouse. Try to set another Background for the Parent Container and I think you'll see the Popup. You can also try to play around with
Point pos = e.GetPosition(null);
until you get the Position you require
