Ionic Push Notification Not Working in android

Hello Ionic Team.

Im using ionic push notification its working fine both platform few day back but now its working in android only. I’m not even change single file. once i push the notification using this curl code terminal.

curl -u SKEY: -H “Content-Type: application/json” -H “X-Ionic-Application-Id: APP ID” -d ‘{“tokens”:[“DEVICE TOKEN”],“notification”:{“alert”:“Hello World!”,“android”:{“collapseKey”:“foo”,“delayWhileIdle”:true,“timeToLive”:300,“payload”:{“key1”:“value”,“key2”:“value”}}}}’

foreground mode its shows alert “Hello world!” but not in background mode. while background mode im getting console like this

Calling onNotification() for a development push. Payload will NOT be available ionic-push.js:115
Object {alert: “Hello World!”} app.js:116
$ionicPush: No device, sending alert instead. ionic-push.js:133

app.js file code snippet

                canShowAlert: true, //Can pushes show an alert on your screen?
                canSetBadge: true, //Can pushes update app icon badges?
                canPlaySound: true, //Can notifications play a sound?
                canRunActionsOnWake: true, //Can run actions outside the app,
                onNotification: function(notification) {
                    console.log(notification)     **Line 116**

                    if(notification.event=='message') {
                    //Im doing some page reduction stuff here.
            return true;


I saw that in iOS the property changed to “body”
