Just need to implement forceStart:ā€œ1ā€ in JSON format and app will be awake from closed app so finally this is my final code with REST API

<===== REST API =====>

 let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    headers.append('Authorization', 'key=' + "**SERVER KEY**");
    let option = new RequestOptions({ headers: headers });
    let body = {
      "data": {
        "title": "TITLE",
        "body": "MSG",
        "forceStart": "1"
      },
      "priority": "high",
      "to": **TOKEN**
    }
    this.http.post('https://fcm.googleapis.com/fcm/send', JSON.stringify(body), option)
      .map(res => res.json())
      .subscribe(data => {
        console.log(data);
        this.autostart.enable();
      });
  }
<===== PusH plugin ====>
const options: PushOptions = {
			android: {
				senderID: '**APP ID**',
				sound: 'true',
				vibrate: true,
				forceShow: "1",
			},
			ios: {
				alert: 'true',
				badge: 'true',
				sound: 'true',
				clearBadge: 'true'
			},
			windows: {}
		};
		const pushObject: PushObject = this.push.init(options);

		pushObject.on('notification').subscribe((notification: any) => {**foreground and background coding**});
		pushObject.on('registration').subscribe((data: any) => {
			console.log('device token -> ' + data.registrationId);			
		});
		pushObject.on('error').subscribe(error => console.error('Error with Push plugin' + error));

Hi Muji,
Could you explain how do you do with OneSignal to send/receive notifications when app is closed/killed ?

30

You donā€™t do anything special.
Notifications are received by default when app is closed.

31

Not for me ā€¦ I can receive notifications when app in foreground or background but not when the app is closedā€¦

32

Is that for Android or iOS?

33

Android, thanks if you can help me

34

Not really sure. It requires a bit of analysis.
Have you checked the OneSignal console? It should have details of each message sent.

Also check if the app is still running from your ā€œapp settingsā€ if the ā€œstop allā€ button is not enabled then the app is fully killed and it wonā€™t receive a notification.
This is the case with all apps, you can try force stop WhatsApp from there and you would see that you donā€™t receive a notification

35

Thanks ! I think the issue is that my app isnā€™t running anymore when I close itā€¦ I donā€™t know exactly how to let it run, but I will try to use the plugin autostart which could help me to run a service of the in background.

36

Hi, you shouldnā€™t need autostart, your phone is probably optimising performance by killing some apps.
Check ur phone settings and any optimising apps you might have installed

38

hi @jbgomez21, have you seen my above solution code and have you try it ?

39

Hi @Anithakor0610, I donā€™t understand where do you have to implement your ā€œREST APIā€ code ā€¦ Do you think your solution works with OneSignal ?

40

hi @Favral this solution works fine with Push notification plugin and REST API you can check this REST API in postman then Apply your API in send message function.
