Azure notification hub UWP, UWP toast notifications don't launch app - azure

Question

i'm using a notification hub for an UWP application following this tutorial : Getting started with Notification Hubs for Windows Universal Platform Apps.
If i test send with a Windows 8 notification like :
<?xml version="1.0" encoding="utf-8"?>
<toast>
<visual><binding template="ToastText01">
<text id="1">Test message</text>
</binding>
</visual>
</toast>
It works and if i click on the notification, it open the app through the OnLaunched() method. But if i send a UWP specific notification like :
<toast launch="app-defined-string">
<visual>
<binding template="ToastGeneric">
<text>Microsoft Company Store</text>
<text>New Halo game is back in stock!</text>
</binding>
</visual>
<actions>
<action activationType="foreground" content="See more details" arguments="details"/>
<action activationType="background" content="Remind me later" arguments="later"/>
</actions>
</toast>
The toast works but if I click on it, it open the app and OnLaunched() never called so the app stuck on spashscreen.
Thanks in advance for your help,
Regards

Answer 1

you need to implement OnActivated in your app.xaml.cs
protected override void OnActivated(IActivatedEventArgs args)
{
base.OnActivated(args);
}

For those who have the same problem, with Dave Smits answer : juste add OnZctivated method in App.xaml.cs file and place same content as OnLaunched method :
protected override async void OnLaunched(LaunchActivatedEventArgs e)
{
await OnLaunchedOrActivated(e);
}
protected override async void OnActivated(IActivatedEventArgs e)
{
await OnLaunchedOrActivated(e);
}
private async Task OnLaunchedOrActivated(IActivatedEventArgs e)
{
// Initialize things like registering background task before the app is loaded
Frame rootFrame = Window.Current.Content as Frame;
// Do not repeat app initialization when the Window already has content,
// just ensure that the window is active
if (rootFrame == null)
{
// Create a Frame to act as the navigation context and navigate to the first page
rootFrame = new Frame();
rootFrame.NavigationFailed += OnNavigationFailed;
if (e.PreviousExecutionState == ApplicationExecutionState.Terminated)
{
// TODO: Load state from previously suspended application
}
// Place the frame in the current Window
Window.Current.Content = rootFrame;
}
// Handle toast activation
if (e is ToastNotificationActivatedEventArgs)
{
var toastActivationArgs = e as ToastNotificationActivatedEventArgs;
// If empty args, no specific action (just launch the app)
if (toastActivationArgs.Argument.Length == 0)
{
if (rootFrame.Content == null)
rootFrame.Navigate(typeof(MainPage));
}
// Otherwise an action is provided
else
{
// Parse the query string
// See what action is being requested
// If we're loading the app for the first time, place the main page on the back stack
// so that user can go back after they've been navigated to the specific page
if (rootFrame.BackStack.Count == 0)
rootFrame.BackStack.Add(new PageStackEntry(typeof(MainPage), null, null));
}
}
// Handle launch activation
else if (e is LaunchActivatedEventArgs)
{
var launchActivationArgs = e as LaunchActivatedEventArgs;
// If launched with arguments (not a normal primary tile/applist launch)
if (launchActivationArgs.Arguments.Length > 0)
{
// TODO: Handle arguments for cases like launching from secondary Tile, so we navigate to the correct page
throw new NotImplementedException();
}
// Otherwise if launched normally
else
{
// If we're currently not on a page, navigate to the main page
if (rootFrame.Content == null)
rootFrame.Navigate(typeof(MainPage));
}
}
else
{
// TODO: Handle other types of activation
throw new NotImplementedException();
}
// Ensure the current window is active
Window.Current.Activate();
}
