I read the implementation of three types of notifications possible in WP7 app - Tile, Toast and Raw Notifications. I understand the use of Tile and Toast Notifications but I fail to understand how a Raw notification will be used in real world application. Can someone please help me understand.
If someone can help me understand the implementation wrt. an existing application like KIK messenger or WhatsApp Messenger, it will be great!

Raw notifications provides the ability for your application service to push data to the application while it is in the foreground without the need for your application to poll the appplication service.
For instance, meaning if you have the Messages application open, and you get a new Message, it'll show a notification (toast), without the Messages application having to poll for it.

If I were to make a messaging app which would involve a user recieving a notification after being messaged by another user, how could i go about setting up the notifications in such a way where they are sent after the message is sent by the user who sent it. If someone could point me in the right direction that would be awesome thank you.
P.S. I am using cloud messaging
I need to imeplement notification badge in navbar similar to stackoverflow where it shows the number if you get any notificaiton.
Similar to this i need to display number as soon as the task progress which initiated from the web app has completed. For this iam using java spring for backend service.
Do I need to call the API frequently to verify the status or is there any better way to implement sth like the socket with spring.
Thanks
I have read the article about Push Notification Service, but I am still confused. I’m a new for MS window phone application developing. My application needs to get the data in the whole class from web service that is for the specific organization. Hope someone can answer my question as below.
In my application, the phone rings and the user answer the phone during sending the request to the web request to get the data. What will happen if the web service sending back the respond?
In the above situation, do I need the Application Push Notification service?
I retrieve the data by using DataContractSerializer. If I need the Push Notification Service, is it meaning that I need to modify the webservice for returning the xml instead of the whole class?
The ongoing call will not disrupt the web request-response flow hence you need not be troubled about it
I'm testing out Windows Phone 7.5 push notifications. I have got the 3 different push types working fine (Toast, Tile and Raw) and am able to send messages from unit tests and a web application without any problems and receive them in my WP application. I want the ability to add extra properties to the push notification and the Raw push type does this perfectly for me and I can add custom key/value pairs or anything else to the push message and extract it on the phone app. I have just found out however that it only works if the application is running and my unit tests fail (suppressed notification status is received in unit test) when the phone application is not running (checked documentation which confirms this too). Is there anyway to add extra properties (key/values) to toast or tile messages or some way I can use raw in another way ? Toast notifications seem limited to a title property and an actual message property but I need to add additional data.
Just wondering if anyone had any suggestions / workarounds ?
The general practice I use is to initially send a raw notification to the device with phone-usable data embedded in the message. If my application is currently running then I can process the contents of the raw message and immediately make use of it on the phone. However if the application is not currently running on the phone you will receive notification from the push servers that the message could not be delievered. If I receive this response I send out a Toast / Tile notification.
With Toast notifications the only parametrisation you have access to is the URI that will launch the application. This is specified with the wp:param node of the message. Eg.
<wp:Notification xmlns:wp="WPNotification">
<wp:Toast>
<wp:Text1>Toast Title</wp:Text1>
<wp:Text2>Toast sub title</wp:Text2>
<wp:Param>/MainPage.xaml?LaunchedFrom=A%20Toast%20Notification</wp:Param>
</wp:Toast>
</wp:Notification>
If the user taps on this toast notification your application will launch and navigate to MainPage.xaml. You can access the querystring passed in via the NavigationContext.QueryString.
Note: The wp:Param node can only be sent to Mango (and up) devices. Additionally the entire contents must be less than 256 characters or you'll receive a PushErrorTypeMessageBadContent error. (Thanks to Ritch Melton for pointing this out). More info available from the Sending Push Notifications for Windows Phone page on MSDN.
As you've discovered, the Microsoft Push Notification Service is very strict in what types of messages you can send and receive. The intent of these push notifications is to provide simple push updates and not large amounts of data. The flexible Raw type seems like it would fit the bill until you discover that:
You can use a raw notification to send information to your application. If your application is not currently running, the raw notification is discarded on the Microsoft Push Notification Service and is not delivered to the device.
However, if you send a toast notification to your application, when the user clicks on the toast the application is started. When your application starts, you should check a service and retrieve the data you are trying to send from a web-service or other remote mechanism.
I am thinking of a simple chat application in Window Phone using Microsoft Push Notification Service.
I read a guide at http://msdn.microsoft.com/en-us/library/hh202967(v=VS.92).aspx which talks about creating a client application that receive toast notification.
This is a first time for me to develop a mobile application so I do not get some part of it.
The question that I have is, is it possible for a client (window phone) to send toast notification directly to other client? I have found below image from the web. It seems that I need to have Cloud Application(probably webserver?) to play with notification service.
Would it be possible to build a Window phone application that directly request to MPNS to send notification to other window phone application? (so from the picture above, '2' will directly point to Microsoft Push Notification Service)
If it is not, what is the reason for that?
There is a good explanation of the push notification service here.
From the above link.
Registration Phase 2: Now that the MPNS known the presence of the
phone on the network, it is required the phone itself provide the Uri
to the Earthquake service. Until this not happen the service doesn't
know there is a phone that need to be notified so it is not able to
provide the notifications. The phone must call a method on the
Earthquake service to provide the Uri that has been answered by the
MPNS. Once the Earthquake service gets this url it can store this
informations somewhere for a later use.
In your case you'll need communication between your devices before any notifications can be sent. This is to know the uri of your phone. A server has to store these uris for all devices registered for notifications. This is why you'll need an application which sends the xml to the MPNS.
