I am New and Creating Xamarin Forms Application , I need Help to Give Message Like "Good Morning" or "Did You Forget to To Login" message Notification to User.
Thanks In advance
There are two kinds of notification you can choose:
Local notification:
Here is the document, local notification send by applications. It can be time or location based, you can also choose repeat or not by config the notification.
Remote notification:
Here is document about remote notification in Xamarin.Android: Google Messaging
Xamarin.iOS: about-remote-notifications
Remote notification send by you. You can choose to send the notification at any time with any content. It is different in iOS and Android. You can read the document for more information.

My question can seems weird, but I just realize that when I receive a push for a new mail from Gmail app and I open Gmail on a web page, the notification disappear.
Can someone explain me how this is working ?
This is related to this question, though it's not an exact duplicate.
This can be implemented with Apple Push Notifications.
Your server has to maintain for each user a list of device tokens of all the devices belonging to that user (iPhones, iPads, etc...).
When the user reads the message on one platform (whether via a web browser or via a mobile application), you can execute some API call on your server to notify it that the user read the message.
Then your server can send a follow-up push notification to all the devices belonging to that user with "badge"=0 (and without the "alert" and "sound" fields), and the notification will be cleared from the lock screen and app icon.
One possibility is that they use notifications delivered in the background (they get delivered directly to the app rather than being shown to the user), then use local notifications. Local notifications can be cancelled.
So it would go like this:
remote notification "there's a new e-mail" delivered in the background
local notification "new email"
...
you connect to the website
remote notification "user has seen new e-mail" delivered in the background
cancel local notification
I've never actually tried to do this, but I suppose that would be the way it works. I'm not aware of any (documented) way to cancel a remote notification directly.
I have successfully created a server that sends Apple Push Notifications, and my iphone receives them.
For example I have Notification of type A and notifications of type B,
How can I control the types of notifications I received on the iphone side? For example I only want type A and not B (Just like Facebook, I want notifications for Friend Request, but not for Walls)
Thanks
you cannot stop your device on receiving a specific type of notification unless it is done on server side. Though you can ignore a notification when app is in running state as you get the notification in didReceiveRemoteNotification and you can simply ignore it after checking it but if app is in background or it is closed then you cannot control the incoming notifications from within your app.
you can make a service on server to set preferences for notification types.
from device, user can enable/disable the push service for individual features and update the preferences on server from device.
On server, before sending the PUSH, you can check for the preferences selected by user from the table and send only those notifications which the user has opted for.
as far as I understand APN's I can only send them to the app not a specific user that uses my app.
Is there a way of sending APN's only to specific users that use my app? I can't think of a way of doing this...

APNS is not a broadcast medium. As it says in the documentation:
Apple Push Notification service transports and routes a notification
from a given provider to a given device.
When you send a notification from the server, one of the paramters is the device ID.
Apple's Push Notifications are always sent to specific 'users' (a specific device being an iphone, ipad)
What you do when you want to use APN is register the application for push notifications. Then you get a token that links the user's device to the notification service. You then use this token to 'push notifications' to APN which will in turn send a notification to that device. Notifications are pushed by 'Providers'.
Here's apple's documentation on the matter: Apple Push Notifications
Look up 'Registering for Remote Notifications' to register the device
and 'Handling Local and Remote Notifications' to handle the incoming notifications.
Read up on how to send notifications here: Providers
It is possible. I use Easy APNS and in newMessage() you can specify the PID (saved in a MySQL database) of the user.
Have a look at http://www.easyapns.com/
Is it possible to get the user's response from a push notification and create a notification reply? i.e. if a user clicks the view button and views the app, can we take that action and let the sender of the notification know that the receiver has viewed / opened the app?
Short answer, Yes.
When the application starts due to a user electing to from a notification (local or remote) the application is started in a special way so that the application can process the notification. At this point it can do whatever you want, like send a message back to your service.
See Handling Local and Remote Notifications for details.
I have just heard that - " push notification " is possible in iPhone
I need following details.
what is push notification ?
How it works ?
What does it requires ?
Any sample code link is available ?
Any documentation link if available ?
Some guidance/tips from "StackOverFlow Masters" about developing the above requirements.
Thanks in advance for sharing your knowledge with Stackoverflow family & me.
The sort of background processing you're looking to do is not possible with push notification.
Push notification allows you to notify the user of something. An example would be a Twitter client that sends a notification when the user receives a direct message on Twitter.
Push notification can not react to things happening on the iPhone when the app is not running. Instead, it depends on you having a server that determines when to send a notification and then sends one.
I'm not seeing any need for background processing in your application. If you store the user's initial location, the next time the app loads you can get their location and calculate the distance between the two. If you're looking for the route travelled, you're out of luck unless you make a deal with AT&T like Loopt just did.
Push notification is not really for that purpose, you should read up on push notification in apples site here http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Introduction/Introduction.html, its more for when theres data like a m essage for your user, you can have the user get it without having them open t he application. Now for your purpose, why cant you store the location when htey close the app, once the reopen the app you can reget a location, use the previous location and the new location to calculate the km travelled?
Although only tangentially related to this discussion, I think you might be interested in Loopt's agreement with AT&T to track user's iPhones (for a monthly fee).
Apple Push Notification service (APNs for short) is the centerpiece of the push notifications feature. It is a robust and highly efficient service for propagating information to devices such as iPhone, iPad, and iPod touch devices. Each device establishes an accredited and encrypted IP connection with the service and receives notifications over this persistent connection. If a notification for an application arrives when that application is not running, the device alerts the user that the application has data waiting for it.
Software developers (“providers”) originate the notifications in their server software. The provider connects with APNs through a persistent and secure channel while monitoring incoming data intended for their client applications. When new data for an application arrives, the provider prepares and sends a notification through the channel to APNs, which pushes the notification to the target device.
