I am developing an application similar to email application.Whenever new message is received my notification service should indicate change to user by updating icon,also, the notification service should continuosly listen to server for incoming events.
I am developing in os version 4.5.
There is no ApplicationIndicator in RIM OS < 4.6 (see bb forum thread)
you have several options to notify the
user (none of them is the indicator,
unfortunately). you can:
play a sound
trigger the vibration
trigger a customizable notification (so the user can decide)
change the application icon
paint a text on the application icon
change the application title
how to show notification icon in v4.2 to v4.5 versions
Play sound with with Alert.startAudio
Change application icon with HomeScreen.updateIcon
Change app name with HomeScreen.setName
Trigger vibration with Alert.startVibrate
And yes, to exchange data between two applications it's better to use GlobalEventListener

In doing some testing on the iOS 11 preview, I've noticed that when I get push notifications while my app is foregrounded the OS displays the system notification that you normally only see when your app is not active.
I didn't see anything announced as having been changed, or any new APIs to change this behavior one way or another. Does anyone know or have links to documentation stating if this is intended, a bug, temporary, or what?
There's an option for showing Push Notifications in the foreground in UserNotification framework.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
willPresentNotification:(UNNotification *)notification
withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
Quoting the comment from the Framework:
The method will be called on the delegate only if the application is in the foreground. If the method is not implemented or the handler is not called in a timely manner then the notification will not be presented. The application can choose to have the notification presented as a sound, badge, alert and/or in the notification list. This decision should be based on whether the information in the notification is otherwise visible to the user.
This could be the place to start looking for the answer.
I am developing one chat application,How its possible to detect user interaction with PC to display status like away or online as we can see in application like skype? If this is specific to only browser tab then we can easily done it with
jquery mouse listener but how its possible at windows level?
I am creating a Mac OS X application to use Notification Center. Some notifications should remain on the screen until the user interacts with them, and others should disappear shortly after displaying.
The NSUserNotificationAlertStyle key and changing System Preferences allow changing between banners and alerts. However, both approaches change all the notifications sent from my application.
Can I send some notifications as alerts and others as banners? If so, how?
NSUSerNotificationAlertStyle is the only way the developer can set the default notification style for the application, and it sets the style for all notifications from that app.
If you think it's really important for you to have 2 different kinds of notifications you can work around the problem by having a hidden helper application with a different NSUserNotificationAlertStyle than the main app.
Remember though you set the default notification style, but the user can change it whenever he wants in the notification center prefs, making your helper app useless.
No. The different notification types exist so that the user may select what he/she prefers, not so that the developer can.
If you feel your app should have this ability, you should file an enhancement request at http://bugreporter.apple.com and let Apple know.
So, Ive made Windows Phone app that contains rss-feeds. I would now like to add the possibility for toasts to popup when a stream is updated. Ive read up on how to use Toasts to notify the user, but how can i make my rss-reader periodically poll the rss-feeds for the latests news when the app is suspended in the background. Example code would be highly appriciated!
Check the "Background Agent Sample" Windows Phone Code Samples to see how you can create a periodic background agent, that will allow you to pool the rss feed(s) and show a toast notification to the user!
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.
