I am trying to implement push notifications in my ionic app.
The challenge is that the network in which the device and the backend service resides is a closed network(no internet).
Is it possible that I get notifications somehow on my app on certain triggers from the backend?
Solutions, I've come across is, sending local notifications from my app while it continuously polls from the server.
The potential problem with this is:
If the app gets closed, the notifications wont show up
Mobile battery will be heavily drained
Is there any other fix to this or any efficient solution?
Any help is much appreciated
Thanks,

I would like to add iOS push notification to my FREE iOS App
The push notification will be mainly advertising my other iOS applications. so I am expecting 1 or 2 push notifications every month
I checked service like urban airship, but I think it is expensive considering I have more than 1.5 Million active users.
So, what I am thinking of is collecting the devices token at Google App Engine ( java ), then whenever I want to send push notifications I export those tokens then send them from my Machine.
Is this is the right approach? what do you think?
Is there any framework that I could use instead of building things from scratch?
Many thanks
This approach looks ok to me. Having an app on Google App Engine to whom each of the iOS device is sending their device token. Later at any time utilizing a web page or web service running on Google App Engine APP you can push custom notification to all respective device tokens. Just keep in mind to filter the list of device tokens with obsoleted ones (in case somebody uninstall your app).
You may check http://code.google.com/p/javapns/ for APNS communication. I tried it couple of times and it worked really well.
You should also give http://www.scringo.com a try.
Among other things this framework does, it also gives you a free push notifications service to send push messages to all your users or some of them (based on your custom criteria).
I have a problem where I don't receive notifications every time I push them to the device. I do receive them occasionally or after a big delay. I'm using the development certificate for APNS and Ruby on Rails on the server side. The server does send notifications to the Apple server its only when I'm receiving them I have a problem.
I initially thought it was a problem with global notifications (tunnel being closed) and to test it I sent my device a notification to Skype which was received almost instantaneously. So, I really dont understand whats the problem here. Is there anything I'm missing or how do I trouble shoot it in depth.
Are push notifications reliable and whats the latency involved? Any help will be greatly appreciated. Thanks
In development, the sending of push notification is not reliable. Some notifications may arrive with some delay. You can try to send notifications in production by building your app in adhoc.
If you haven't the same result with different iphone/ipod, you can try to reset network settings device.
i m making an application where data is accesed from website and displayed with an application.i have made an action which will tell the user that new data has arrived.this will work properly if the application is open .but if the application is closed than ,is there any way to tell the user that new data has arrived ,,so that he can open the application and check the data?
If you are using the Apple Push Notification Service (APNs), your messages will be delivered whether the application is running or not. For information on how to control what information is presented to the user, read the Apple Push Notification Programming Guide.
You should use Apple Push Notification Service, like codelark said.
I would recommend looking into Urban Airship for help getting started. It's a third party service, but it makes things much easier. Urban Airship does have their own tutorials and code samples which may be easier than Apple's.
As a follow up to the reference to apple push notification, as of ios4.0 I believe you, you may have a few more options, 1) you can send local notifications (just like push notifications, but they originate from inside your app) that could be timed to be delivered even if the app is not running..assuming you know approximately how long it will take for data to arrive. 2) if your data update will occur soon after the app closed.. your app can request a certain amount of time to complete an operation (even though the user has closed the app) and wait for the data, then send a local notification to tell the person to come back into the app. 3) if your functions based on gps updates, music streaming, or voip you can set a flag so your app continues to run in the background
sorry for the unstructuredness of the answer, this was just off the top of my head, hope it helps
How are push notification better than pull notification on iPhones?
Are there any links with more information about this?
Any help would be appreciated.
Pull notification requires the user to be running your app, and your app to be wasting battery power constantly polling some server (or waiting on some network socket in another thread , or using the new background services).
Push notifications, when enabled by the user, and if the phone has a network connection, allows a message to be sent to a phone even when it's not running your app, prompting the user that your app wants some attention. It uses a much lower power network connection than any frequent polling method.
If you want to know about push notifications, I'm guessing you are interested in the Apple Push Notification Service.
You can read about its architecture here:
http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html
There is no such thing as a "pull" notification, but using APNs gives you the advantage that you don't have to manually poll a server every so often within an app, which usually saves you a lot of battery life in the long run if you are interested in telling the user about sporadic, infrequent events. Using push notifications also allows you to interrupt the user if they are not currently running your app, which of course can be very useful in certain use cases.
You should think about what kind of message flow you expect to see between your app and any server components in your system. Push notifications make the most sense where some event external to your app is going on which requires the app to be updated in some way, and where the frequency of those updates is low or highly variable.
I'm looking for a way to get real time notification from a server in an iPhone App. I don't want to use Apple Push Notification as I have many notifications. My web service is coded in PHP, and I haven't figured out an easy way to implement this functionnality. Any idea what should I do?
Thx a lot for your help!
EDIT : I'm looking for a way to get notification only when the app is launched (otherwise, the only option IS Apple Push not.).
If the app is running you can open an http connection from the app to the server and have the server hold it open, pushing data through it when you want. This is basically how COMET works.
This will only work while your app is running. If you need the notification to happen even if the user has closed the app then Apple Push Notifications are your only option.
You must use Apple Push Notification for achieving push notifications cycle on Apple's mobile devices.
