[Xamarin.Droid] Handle pushes automatically when app is in foreground

Question: When my app is in foreground i am able to see the notification in notification tray too. How can I remove it and how to handle push payload automatically?

Answer:

This is a default behavior for our SDK. If you want to override it and handle notifications in a specific way, you need to create a custom Notification Service Extension and override OnMessageReceived method. In order not to show a notification in tray, you should just return true with OnMessageReceived. Please find a short code snippet below:

public class NotificationServiceExtension : Pushwoosh.Notification.NotificationServiceExtension
{
    public static Activity CurrentActivity { get; set; }
    protected override bool OnMessageReceived(PushMessage message)
    {
        if (IsAppOnForeground)
        {
            Handler mainHandler = new Handler(ApplicationContext.MainLooper);
            mainHandler.Post(() =>
            {
                HandlePush(message);
            });
            return true; // true indicates that a notification should not be shown
        }
        return false; 
    }

    protected override void StartActivityForPushMessage(PushMessage message)
    {
        if (!HandlePush(message))
        {
            base.StartActivityForPushMessage(message);
        }
    }

    [MainThread]
    bool HandlePush(PushMessage message)
    {
        // your custom foreground push handling here
    }
}

If you want to perform additional actions (i.e. handle push payload) when receiving a push, you should also do it in your OnMessageReceived (HandlePush function in example above).
