Location is not being sent when app is closed. Can anyone point out what i am missing?

I am working on an Ionic app. I am trying to send location in background every 1 hour. I am using official Background Geolocation plugin. Location is being sent when the app is open either in foreground or background but as soon as i close the app my location is not being sent to database. Although my debug mode is active and i can see toast message and beep sound even after closing app. Can anyone point out where i am making mistake? Here is my code.

{
platform.ready().then(() => {
this.getLocation();
this.backgroundGeolocation.start();
});
}

getLocation() {
const config: BackgroundGeolocationConfig = {
  locationProvider: this.backgroundGeolocation.LocationProvider.ANDROID_DISTANCE_FILTER_PROVIDER,
  desiredAccuracy: 10,
  stationaryRadius: 5,
  startOnBoot: true,
  notificationIconColor: '#4CAF50',
  interval: 5000,
  fastestInterval: 5000,
  activitiesInterval: 5000,
  distanceFilter: 5,

  debug: true, //  enable this hear sounds for background-geolocation life-cycle.
  stopOnTerminate: false, // enable this to clear background location settings when the app terminates
  stopOnStillActivity: false
};


this.backgroundGeolocation.configure(config).subscribe((location) => {
  this.loc.push(location);
  this.storage.save('Location', this.loc).subscribe();
  console.log('Location :', location);
  this.sendLocation(location);
});

}

sendLocation(data) {
const url = 'my-url';
const payload = {
  date_added: moment(data.time).format('DD/MM/YYYY'),
  identity: '',
  ipaddress: '',
  latitude: data.latitude,
  longitude: data.longitude,
  mobile: 'phoneNo',
  network_name: '',
  status: '',
  time_added: moment(data.time).format('hh:mm A'),
}
this.http.post(url, payload).map(res => res.json()).subscribe(data => console.log('location inserted: ', data))

}

Please edit your post, it is not very readable at the moment.
Use the </> button above the input field to format your code, command line output or error message (select the text first, then click the button or wrap it in ``` manually). Check the preview if it looks better. This will make sure your text is readable and if it recognizes the programming language it also automatically adds code syntax highlighting. Thanks.

The Background Geolocation Plugin only works when your is running in foreground or background. It doesn’t work when the app is closed.

Sending the user’s Geolocation every x minutes (even when the app is closed) won’t work.
You could take a look at geofences, maybe that already helps to meet your requirements. Geofences will be checked even when the app is closed.
