I am using following plugin for push notification in Ionic2
http://ionicframework.com/docs/native/push/
Expected Behaviour: When app is closed, And notification received, And when user tap the notification, on("notification") event should fire after app opens.
Actual Behaviour: I am getting notification successfully. But When Application is in background or closed, at that time when I receive notification and I tap the notification, on("notification") event is not firing.
Cordova version 7.0.1 Android version 6.2.3
My code:
this.platform.ready().then(() => {
this.pushsetup();
});
private pushOptions: PushOptions;
private pushObject: PushObject;
pushsetup() {
// to check if we have permission
this.push.hasPermission()
.then((res: any) => {
if (res.isEnabled) {
console.log('We have permission to send push notifications');
// configuration of push notification
this.pushOptions = {
android: {
senderID: 'XXXXXXXXXXX',
icon: 'icon_notification'
},
ios: {
alert: 'true',
badge: true,
sound: 'false',
senderID: 'XXXXXXXXXXX'
},
windows: {}
};
this.pushObject = this.push.init(this.pushOptions);
// attach push events
this.storage.get('isPushRegistered')
.then(isPushRegistered => {
if( !isPushRegistered ){
this.pushObject.on('registration').subscribe((registration: any) => {
console.log('Device registered', registration)
this.storage.set('isPushRegistered', true)
});
}
})
this.pushObject.on('notification').subscribe((notification: any) => {
console.log('Received a notification', notification)
});
this.pushObject.on('error').subscribe(error => console.error('Error with Push plugin', error));
}
});
}
So, on my code, you can see this.pushObject.on('notification') event. that is not firing when app is closed.
Thank you for your time and support.
This is not the issue with client side code. This issue is occuring because of the notification payload.
From Official docs of phonegap-plugin-push
Notifications behave differently depending on the foreground/background state of the receiving app and the payload you send to the app.
For instance if you send the following payload: phonegap-plugin-push/
{
"notification": {
"title": "Test Notification",
"body": "This offer expires at 11:30 or whatever",
"notId": 10
}
}
When your app is in the foreground, any on('notification') handlers you have registered will be called. However, if your app is in the background, the notification will show up in the system tray. Clicking on the notification in the system tray will start the app but your on('notification') handler will not be called as messages that have notification payloads will not cause the plugins onMessageReceived method to be called.
If you send a payload with a mix of notification & data objects like this:
{
"notification": {
"title": "Test Notification",
"body": "This offer expires at 11:30 or whatever",
"notId": 10
},
"data" : {
"surveyID": "ewtawgreg-gragrag-rgarhthgbad"
}
}
When your app is in the foreground any on('notification') handlers you have registered will be called. If your app is in the background, the notification will show up in the system tray. Clicking on the notification in the system tray will start the app and your on('notification') handler will not be called as messages that have notification payloads will not cause the plugins onMessageReceived method to be called.
My recommended format for your push payload when using this plugin (while it differs from Google's docs) works 100% of the time:
{
"data" : {
"title": "Test Notification",
"body": "This offer expires at 11:30 or whatever",
"notId": 10,
"surveyID": "ewtawgreg-gragrag-rgarhthgbad"
}
}
When your app is in the foreground any on('notification') handlers you have registered will be called. If your app is in the background, then the notification will show up in the system tray. Clicking on the notification in the system tray will start the app, and your on('notification') handler will be called with the following data:
{
"message": "This offer expires at 11:30 or whatever",
"title": "Test Notification",
"additionalData": {
"surveyID": "ewtawgreg-gragrag-rgarhthgbad"
}
}
