Android App start Notification

hi
i have one doubt about development in “Unity Android”, i have um app to get some notifications comparing the date, like date xx/xx/xxxx show a notification “you have a event today” like a calendar notification

but the app can be close by the user, has to be a service? its possible to do that?

Yes possible.

What we did in our plugin was,

  1. Create an Alarm alert with AlarmManager with a repeat setting a required interval.
  2. Once it fires the event, receive it in a BroadcastReceiver
  3. Fire a Notification based on your logic about date comparison.
