Toasts Notification Plugin for Xamarin and Windows

A simple way of showing notifications inside your Xamarin or Windows application. In windows phone world we call them "Toasts". This plugin uses the platforms native toast / notification API's.

Setup and usage

Setup

Platform Support

Platform Supported Version
Xamarin.iOS No
Xamarin.iOS Unified Yes iOS 10+
Xamarin.Android Yes API 16+ (AppCompat Only)
Windows Phone Silverlight No
Windows Phone RT No
Windows Store RT No
Windows 10 UWP Yes 10+
Xamarin.Mac No

Now uses .NET Standard 1.3, does support PCL 111.

iOS Support Version 3+ of this plugin requires iOS10 to display the toast notification. If you require support for iOS7+ then please use version 2.0.4.

I you want to use the latest plugin with a version less than iOS 10 you can hook into the ReceivedLocalNotification in the AppDelegate to display an Alert.

Setup

In your iOS, Android, WinRT and UWP projects please call:

DependencyService.Register<ToastNotification>(); // Register your dependency
ToastNotification.Init();

// If you are using Android you must pass through the activity
ToastNotification.Init(this);

If you are using Xamarin Forms, you must do this AFTER your call to Xamarin.Forms.Init();

Usage

Use dependency service in order to resolve IToastNotificator.

var notificator = DependencyService.Get<IToastNotificator>();

var options = new NotificationOptions()
            {
                Title = "Title",
                Description = "Description"
            };

var result = await notificator.Notify(options);

The result that is returned is a NotificationResult with an Action inside with one of the following values.

[Flags]
public enum NotificationAction
{
    Timeout = 1, // Hides by itself
    Clicked = 2, // User clicked on notification
    Dismissed = 4, // User manually dismissed notification
    ApplicationHidden = 8, // Application went to background
    Failed = 16 // When failed to display the toast
}

If you want the Clicked NotificationAction you must set IsClickable = true in the NotificationOptions.

Permissions

In iOS you must request permission to show local notifications first since it is a user interrupting action.

// Request Permissions
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
{
    // Request Permissions
    UNUserNotificationCenter.Current.RequestAuthorization(UNAuthorizationOptions.Alert | UNAuthorizationOptions.Badge | UNAuthorizationOptions.Sound, (granted, error) =>
    {
        // Do something if needed
    });
}
else if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
    var notificationSettings = UIUserNotificationSettings.GetSettingsForTypes(
    UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound, null);

    app.RegisterUserNotificationSettings(notificationSettings);
}
