I am developing an application in windows phone which having push notification facility. I am able to receive push message at device.
If Application is not running , I am getting message at home screen on the click of that msg it starts that application. I want to perform some task on the basis of that Push Notification Message. But i am not able to handle that event.
Please help me to handle that EVENT if application is running or application is in background or application is not running .
Thanking You,
Which type of notification are you sending? Based on your question I assume you are referring to toast notifications.
When do you want to perform the task - before or after the user clicks on the message? If the application is not running, you can only do it after clicking the message.

I am working on an application with ionic and angularjs. I would like, that the app checks automatically in the background, if new database entries are available. If yes, it should send a notification. My question: How can I check in the background continiously, if there is an database update?
And Question #2: If there is no entry in the database, it should throw you out of the actual page.
Background: I am working on an live-survey app for events, with which you can interact with the show on the stage. If a question is activated for the people, you should get a notification.
1 - for continuously checks you should use cron job from your server side and based on it you can send your notifications
2- if there is no entries you can send push notification with any flag in its payload and check on it in the mobile app then execute the desired behavior.
I am working on a Windows Phone 8.1 silverlight app, raw notifications handling.
The App when receives notifications in foreground, has to cancel the notification and create a new notification using ToastNotificationManager.CreateToastNotifier().
It also has a backgroundtask to work on the raw notifications received in background, which converts the raw notifications received to toast notification using ToastNotificationManager.CreateToastNotifier().
Also some action A needs to be performed on clicking of this notification.
The issue arises when the App receives the notification when in foreground, but the notification is clicked after suspending the application. Since the registered activated event of such type of notification is not in the background task (because the notification was formed in the foreground logic), no action A is performed on clicking of the notification.
This seems to a limitation, for WP8.1 silverlight apps. Can somebody suggest a solution for this issue??
If you need to do some action after tap on Toast you should add wp:Param to your Toast with deep url and handle in you app.
Toast will be look like
<wp:Notification xmlns:wp=\"WPNotification\">
<wp:Toast>
<wp:Text1>You title</wp:Text1>
<wp:Text2>Your subtitle</wp:Text2>" +
<!-- You can add any parameter you want in deep url -->
<wp:Param>/Page2.xaml?NavigatedFrom=Toast Notification</wp:Param>
</wp:Toast>
</wp:Notification>
When you tap on toast it by default will open Page2.xaml of your app and pass uri parameters to it
I have implemented Fast resume in my windows phone 8 app and its working fine in every case except following scenario.
Steps:
1)Phone is password locked
2)Toast is received.
3)Tap on toast.
4)App is activated.
5)The page which was last on backstack opens up with reset state.
6)No more navigation
In Fast Resume app should receive one more navigation with deep link on tapping on toast which is missing in this case.
Please find sample here.
This feature of Windows Phone. If the reminder or toast to send from your lock screen (even without a password), the navigation application is limited. I think that there is no way now to fix this behavior ...
I got even more unpleasant situation with reminders of the applications:
1) If screen is not locked and you gave a reminder of the application, then click on the reminder will open the application, you can immediately take action in response to the reminder. All well and good.
2) when the lock screen (even without a password) and you send a reminder of your application, there is no ability to navigate the application by clicking the reminder. Reminder, you can only cancel or postpone for a while. Then the user must unlock the screen, open the program and try to understand what to do in response to this reminder.
At least toast is displayed in the notification center, and the reminder disappears without a trace and the user attempts to find what caused the reminder.
I do not understand why such inconvenient behavior for user application communicates with the lock screen.
Wrote a post on UserVoise, but without response.
Enable to open a task or an appointment directly by tap on the reminder
I'm working on a Windows Phone app that will receive push notifications and needs to show critical alerts to the user. As far as I can see there are 3 types of push notification:
Raw Notification - Raw notifications are used when your application is actually running on the device. This allows you to
update your interface “live” as the user is using it.
Toast Notification – This message will be received regardless of whether your application is running or not, but popping toast messages
while your app is running might be a little annoying. I’ll
demonstrate this example below. Toast WILL NOT also update your
application’s data. You still need to pass a Raw Notification to make
this happen.
Tile Notification – If your application is pinned to the user’s Start screen, you can update the Tile for your application. You can
change the background image, as well as an integer from 0-99.
source: http://www.jeffblankenburg.com/2010/10/19/31-days-of-windows-phone-day-19-push-notifications/
These each have different behaviours, but none lend themselves to critical notifications, where the user can be actively alerted to critical information.
Having read Guidelines for toast notifications on MSDN, it suggests
Don't use toast notifications to notify the user of something that
must be seen, such as a critical alert. To ensure that the user has
seen your message, notify them in the context of your app with a
Flyout, dialog, app bar, or other inline element.
So the question is, how can I trigger a "flyout, dialog, app bar or other inline element" if my app is closed and the phone receives a critical notification.
long story short: you can't enforce that your app opens on an incoming pns
But I think you've got the toast scenario wrong. A toast can be used to notify the user, if he taps it the app opens and you might react to that by the navigation uri (e.g.: ?fromToast=true).
If you receive a toast notification while your app is open the toast won't show. Toast Notifications only get displayed when your app isn't open. But you can react to an incoming toast notification (there's an event for that) to implement an behavior of your way (e.g.: flyout, msgbox, ...).
note: introduced with GDR3: The sound of the toast notification can now be changed (even made silent).
I would like to know what is the clean & correct way to notify my WP8 app that the ChannelUri has changed?
I read that i need to handle this in the ChannelUpdatedUri method. But i have a few queries here. Doesn't this require my app to be running all the time?
Second query is suppose i use ChannelUpdatedUri to listen for changes to the Uri. If there is a change will the app be notified as soon as it launches? Or will it be notified at a later time?
The trouble is if the app is not notified on launch then there is a possibility that it may re-register for a new channel uri before ChannelUpdatedUri is invoked. Isnt it?
Please help!
You'll only get notified of a change in the ChannelUri when you have the listener attached and the app running.
The best approach is to always check for the current Uri and pass it to the server when the app starts. You could leave the listener attached for the lifetime of your app and get a new one if it's lost while the app is running but in reality it's far more likely that the channel will be dropped/disconnected when the phone isn't in use.
There is, of course, the scenario where a channelUri may expire when the app isn't in use but the utility of the app is primarily around sending notifications. Obviously you need the user to restart the app to get a new connection but you can't tell them to restart the app.
This is a generic problem: how do you tell someone that you can't talk to them?
The reality of this situation is that if you really need to tell someone to launch the app again you'll need another way to do it.
Unfortunately, it's not possible to get an updated channelUri from a background agent, but you could query your backend to see if you need one and then raise a toast to the user to prompt them to reopen the app. Or you could just update the tile from the agent when this happens.
Alternatively you'll need to send them the prompt in another way (e.g. email or SMS?) but this is reliant on you capturing and securely storing these details.
There is no perfect solution to this scenario other than creating an app that the user opens regularly regardless of whether there are notifications or not and simply having the notifications as an extra feature.
