Push Notifications - Get Badge Count

[Joe]

I'm using the push notification plugin (http://docs.telerik.com/platform/backend-services/javascript/push-notifications/push-getting-started).

Everything is working great so far, I can submit new notifications from the Backend Services REST Api, the notification displays on the device and the app icon badge number is set.

I need to be able to get the badge count and display how many notifications a user has when they log into the app.

I noticed that there are push.setBadgeNumber and push.clearBadgeNumber functions, but there is no push.getBadgeNumber function.

http://docs.telerik.com/platform/backend-services/javascript/apireference/JavascriptSDK/Push/push.setBadgeNumber

I decided to try out the Badge Cordova plugin (http://plugins.telerik.com/cordova/plugin/badge), but it isn't working, it always returns zero, even if the icon has a number.

Here's my code for getting the badge count:

if (window.cordova) {
        document.addEventListener("deviceready", function () {
            if (navigator && navigator.splashscreen) {
                navigator.splashscreen.hide();
            }           
            bootstrap();
            if (!window.navigator.simulator) {
                window.screen.lockOrientation("portrait");
                cordova.plugins.notification.badge.get(function (count) {                   
                    console.log("Current badge: " + count);
                    if (count > 0) {
                        $("#badgeCount").text(count.toString());
                        $("#badgeContainer").show();
                    }
                    else {
                        $("#badgeContainer").hide();
                    }
                });
            }
        }, false);
    }
    else {
        bootstrap();
    }

Any suggestions?

Hi Joe,

When sending a push notification to iOS you can set the IOS.aps.badge number in the payload.
It will be set on the app icon. In the notification received callback you will receive a badge property with the value of the badge at the moment. Make the required calculations and set the device badge count from the app using the methods for controlling the badge count.

var onNotificationAPN = function(e) {
    alert(JSON.stringify(e));
    var badgeCount = parseInt(e.badge);
    // alter the badge count here
};

I hope this helps.
