Xamarin is a programming language based on the C # programming language. With CAM-based programming in xamarin, you can get three different outputs at the same time, outputs for Android applications, IOS applications, and Windows applications.
What are push-notifications?
Push notifications are notifications that are sent to users by the server without the user request. Push-notifications are called notifications because notifications are sent to users by the server without the user's request. Of course, this does not mean that the server can send any relevant or unrelated information to the user, but it does mean that the user first activates the service and makes the relevant settings and notifications from The server side is sent to it automatically before the user requests.
Users can change the settings for push-notifications if needed or even disable them if they wish.
One of the most important features and benefits of push-notifications is that no special program is required to receive these notifications, and notifications will be sent and received even when the phone screen is off.
Updates are done on smartphones with different Android and IOS operating systems. Developers of these operating systems also use different methods to send notifications. Developers of the Android operating system use Google Cloud Messaging or Firebase Cloud Messaging service to send information to phones with the Android operating system. The Apple Push Notification Services API is used to send information to iOS operating systems.
How are push-notifications sent?
There are different technologies for sending pressure notifications for each site, and the company uses different technologies to send pressure notifications on their site.
These technologies include the following:
• Apple Push Notification Service (APNS)
• Google Cloud Messaging (GCM)
• Windows Push Notification Services (WNS)
Sending push-notifications cannot be done directly. To send notifications, you must make sure that there is a support service; after the user confirms to send push-notifications, automatically and before the user requests, the site notifications are sent to the user be.
Launched in 2001, the Mono developers organized the platform. Xamarin is an open-source platform built on the .NET framework that provides opportunities for development in the Microsoft environment. Following the announcement of Xamarin as an open-source platform, it became part of the Xamarin Visual Studio Integrated Development Environment (IDE).
Xamarin can also be used to send push-notifications to extended applications. This is usually the same as sending notifications via Google Firebase
. The Firebase Cloud Messaging Service (FCM) is available for sending message notifications and more.
How to enable XAMARIN push-notifications:
Azure notification hub is commonly used to send notifications to an Android Xamarin app. These notifications are played on all Android devices using the Firebase Cloud Messaging feature.
Hub is used to transfer information to Xamarin.Forms applications. Transfer notifications to Xamarin.Forms applications used to target Android and iOS operating systems. To use the best and latest installation methods, it is best to use the ASP.NET Core Web API extension, which sends push-notifications and notifications cross-platform.
In this tutorial, you will learn the following note:
• Set up Push Notification and Azure Notification Hub services.
• How to setup google notification cloud-messaging or Firebase Cloud-Messaging (FCM)
• How to implement push notifications for
Android apps.
• How to implement push notifications for
iOS apps.
• How to send push notifications.
• How to receive and process push notifications.
Basic Requirements:
• Mac computer with Visual Studio installed.
• Install Xamarin and .NET with Visual Studio.
• Ability to run a Xamarin application on both Android and iOS platform.
• Physical device or emulator (capable of running API 26 and above using applications installed on the Google Play service.)
Implementation of Push-Notification on Xamarin-Android:
1- Go to https://console.firebase.google.com and signup and create a project for your app. (this will be useful for all platforms)
2- In the cloud-messaging settings, download and add google-services.json to Xamarin.Android project root.
3- Right click on google-services.json in Visual studio and set the buildaction => googleJson
4- Install NuGet package => xamarin.firebase.messaging for android 60.11
5- Install NuGet package => xamarin.googleplayservices.base
6- remove all green-icon android support nuget pacakages (if exist)
7- update all other available nugets
8- Add this Code to your AndroidManifest.xml file inside the application tag.
9- In your MainActivity.cs File, you can add this:
10- Create a class in you Xamarin.Android project and add this code:
Implementation of Push-Notification on iOS:
1- Go to https://console.firebase.google.com and click on the same project you created on Android section.
2- add GoogleService-Info.plist to your iOS project root
3- right click on GoogleService-Info.plist on Visual studio, and in properties, set the buildaction => bundleresource
4- Install nuget package => Xamarin.Firebase.iOS.CloudMessaging
5- Install nuget package => xamarin.googleplayservices.base
6- remove all green-icon android support nuget pacakages (if exist)
7- update all other available nugets
8- Apple developer account -> in Certificates, IDs & Profiles -> Keys -> create APN key -> upload it in firebase console.
9- Apple developer account -> Certificates -> add certificate for notification for this specific app project.
10- In you Xamarin.iOS project your AppDelegate.cs file will look like this:
11- Create a class in you Xamarin.iOS project and add this code:
Note:
IOS emulator cannot support remote notifications, it is better to use a physical device to support them.
Without the need for previous experience or technical knowledge, by mentioned and following steps of this training and observing its principles, you can get acquainted with and benefit from the following aspects.
• Xamarin and
Xamarin forms
• Google Firebase console
• Microsoft Azure and how to send push notifications through Azure Notification Hubs.
• Apple Developer Portal
• ASP.NET Core and Web API
How to set up Push Notification and Azure Notification Hub services (For UWP platform)
Azure notification hub hub is usually used to send notifications to a Xamarin Android application. These notifications are broadcasted over all the android devices using the Firebase Cloud Messaging feature.
To send push notifications to follow the below-given steps:
1- You have to create a Firebase project and have to enable the
Firebase Firebase Cloud Messaging feature.
2- Now create a notification hub.
3- Introduce the Xamarin.Android app and develop a connection with the notification hub.
4- Now send test notifications from the Azure portal.
ENABLING FIREBASE CLOUD NOTIFICATION:
1- Sign in to Firebase console and create a new project.
2- Add Firebase to your android application
3- Declare a name for the application, register your app, download googleservices.json.
4- Select project settings, make a selection on the Cloud Messaging option on the top, and save the generated server key.
DEVELOPING A MICROSOFT NOTIFICATION HUB:
1. Enter the Azure portal
2. Select the notification center in the mobile section.
3. In the generated page, select Add, enter a name, select a value for the location and a group of available resources.
4. Select the provided access policies.
Establish a connection between ANDROID APP and Hub Alert:
1. Create a VS project.
2. Select the available File option, then click on the project.
3. In your project, expand Visual C #, click on Android and select Android App (Xamarin).
4. Now after that, announce a name for the project and select the location, and finally select ok to continue your work.
You will be notified that you must have an Azure account, a Visual Studio with Xamarin on Windows, or a Visual Studio for Mac on OS X and an active Google Account.
Some of the main features of Xamarin are:
• Use of a single language: Xamarin • only uses C# as a native tool for the development of mobile-based applications. Unlike other interpreters, it is a go-to precision for building high-performance applications.
• The .NET framework comes across many features like LINQ, Asynchronous programming, Lambdas, and, based on C#, can be used as a tool for better programming aspects.
• Xamarin supports access to the latest APIs to acquire its capabilities in applications such as in ARKit on IOS or Android Multi-Window.
