Usage

Once after the setup, import the namespace to access the features from Notification Services.

using VoxelBusters.CoreLibrary;
using VoxelBusters.EssentialKit;

Request Access (for presentation options)

A notification can have a visual display, sound, badge and other properties. You need to request them based on how you want to present the notifications to the user with RequestPermission method.

NotificationServices.RequestPermission(NotificationPermissionOptions.Alert | NotificationPermissionOptions.Sound | NotificationPermissionOptions.Badge, callback: (result, error) =>
{
    Debug.Log("Request for access finished.");
    Debug.Log("Notification access status: " + result.PermissionStatus);
});

Check for other permission options in NotificationPermissionOptions available on iOS specifically.

Get Settings

You can check what settings user allowed with GetSettings method. This will be handy if you want to check if user denied the settings so that you can prompt him with suitable message.

NotificationServices.GetSettings((result) =>
{
    NotificationSettings settings    = result.Settings;
    // update console
    Debug.Log(settings.ToString());

    Debug.Log("Permission status : " + settings.PermissionStatus);
});

If you see user didn't allow the permission earlier, you can use Utilities. OpenApplicationSettings method to let user to enable the permission for using the notifications display feature.

Local Notifications

Create a Notification Message

For scheduling notifications, you need to create an instance of INotification.

INotification notification = NotificationBuilder.CreateNotification("notifId")
    .SetTitle("Title")
    .Create();

Schedule Notification

For scheduling a notification, you need to have an instance of INotification which contains the details required for a notification. Use ScheduleNotification for scheduling the notification.

NotificationServices.ScheduleNotification(notification, (success, error) =>
{
    if (success)
    {
        Debug.Log("Request to schedule notification finished successfully.");
    }
    else
    {
        Debug.Log("Request to schedule notification failed with error. Error: " + error);
    }
});

The above call will schedule the notification instantly and incase if you want to schedule in the future, you need to set the Time Interval Trigger

INotification notification = NotificationBuilder.CreateNotification("notif-id-1")
    .SetTitle("Title")
    .SetTimeIntervalNotificationTrigger(10) //Setting the time interval to 10 seconds
    .Create();

Triggers

Scheduling a notification needs to specify at what time it needs to trigger. Plugin offers currently two ways to trigger a notification

• Time Interval Notification Trigger

• Calendar Notification Trigger

Time Interval trigger can be used if you know the exact time in seconds if you want to schedule a notification. This offers repeat option as well where it repeats for every scheduled interval seconds.

Calendar trigger can be used if you want to schedule a notification at a specific time of the day or week or month or an year. This is very useful for better control and for timely notifications like daily rewards or birthday offers etc.

Repeat Notifications

When setting the time interval notification you can pass additionally repeat status to repeat the notification. The below notification repeats every 10 seconds.

INotification notification = NotificationBuilder.CreateNotification("notif-id-1")
    .SetTitle("Title")
    .SetTimeIntervalNotificationTrigger(interval: 10, repeats: true) //Setting the time interval to 10 seconds
    .Create();

Get Scheduled Notifications

You can get the list of all scheduled notifications and not yet delivered with GetScheduledNotifications

NotificationServices.GetScheduledNotifications((result, error) =>
{
    if (error == null)
    {
        // show console messages
        INotification[] notifications   = result.Notifications;
        Debug.Log("Request for fetch scheduled notifications finished successfully.");
        Debug.Log("Total notifications scheduled: " + notifications.Length);
        Debug.Log("Below are the notifications:");
        for (int iter = 0; iter < notifications.Length; iter++)
        {
            INotification notification    = notifications[iter];
            Debug.Log(string.Format("[{0}]: {1}", iter, notification));
        }
    }
    else
    {
        Debug.Log("Request for fetch scheduled notifications failed with error. Error: " + error);
    }
});

Cancel Scheduled Notification/Notifications

As each notification has an unique Id (assigned when creating), you can cancel the notification with this id.

NotificationServices.CancelScheduledNotification("notif-id-1");

Cancel all scheduled notifications

NotificationServices.CancelAllScheduledNotifications();

Get Delivered Notifications

GetDeliveredNotifications return all the notifications delivered in the Android or iOS notification center.

NotificationServices.GetDeliveredNotifications((result, error) =>
{
    if (error == null)
    {
        // show console messages
        INotification[] notifications   = result.Notifications;
        Debug.Log("Request for fetch delivered notifications finished successfully.");
        Debug.Log("Total notifications received: " + notifications.Length);
        Debug.Log("Below are the notifications:");
        for (int iter = 0; iter < notifications.Length; iter++)
        {
            INotification notification    = notifications[iter];
            Debug.Log(string.Format("[{0}]: {1}", iter, notification));
        }
    }
    else
    {
        Debug.Log("Request for fetch delivered notifications failed with error. Error: " + error);
    }
});

Remove Delivered Notifications

RemoveAllDeliveredNotifications removes all notifications delivered in the Android or iOS notification center .

NotificationServices.RemoveAllDeliveredNotifications();

Push Notifications or Remote Notifications

While local notifications are created locally and delivered to the device, Push notifications needs an external/backend server to deliver the notification to device.

Go through the following steps to understand how a push notification works.

1. Device registers for push notifications and receive a token

2. The token(also known as device token or registration token) will be sent to your backend server

3. Your backend server constructs the message payload it wants to pass to your device and sends a request to the platform's notification servers (APNS on iOS and FCM on Android) along with the device token it received in step 2.

4. Platform's notification servers then targets the device with the device token and pushes the message payload to the device.

5. Yay! 👯‍♂️ Your device will receive a notification!

Remote Notifications Management

For getting the device token, you first need to register for push notifications. In the callback, you get the device token.

NotificationServices.RegisterForPushNotifications((result, error) =>
{
    if (error == null)
    {
        Debug.Log("Remote notification registration finished successfully. Device token: " + result.DeviceToken);
    }
    else
    {
        Debug.Log("Remote notification registration failed with error. Error: " + error.Description);
    }
});

Once after registration, the plugin caches the device token for your future usability. You can fetch with NotificationServices.CachedSettings.DeviceToken

Also, you can check if remote notifications are already registered on the device with IsRegisteredForRemoteNotifications

bool    isRegistered    = NotificationServices.IsRegisteredForPushNotifications();
Debug.Log("Is registered for remote notifications: " + isRegistered);

Once you are done with the remote notifications, you can unregister for the push notifications.

NotificationServices.UnregisterForPushNotifications();

If your user disables the push notifications, unregistering for remote notifications will save battery on the device!

Detecting App launch through Notification

There will be cases where you need to identify if the app is launched when user clicked on the notification from Notification Center.

INotification has a property IsLaunchNotification property which tells if the notification is launched on user tap.

Plugin automatically delays delivering the notification until you register for NotificationServices.OnNotificationReceived event. Once you register, plugin delivers with IsLaunchNotification variable set to true if it's tapped by the user.
