hi as I would like to be able to run some code when the app is closed
(for closed I mean closed by the task manager).
my app must be able to make http requests via axios in the background on both android and ios (must send notifications using the local-notification plugin that reminds that one or more events in an external calendar will start in an hour), I searched in network and I saw the documentation but it is not clear how I should do, I also read that the way to run background code on android 8 changes radically.
Can someone explain to me what I have to do? what permissions should I request from the system? or if there is any example of code on the net.

Okay you should use a service in android.It's a simple class makes it happen in the background and after you're done you can stop the service.It works for android up to 26 api.(26 not included)

https://developer.android.com/guide/components/services

for 26 and higher you can use Managers there's a downloadManager already:

https://developer.android.com/reference/android/app/DownloadManager

You don't have to use it,you can also make yours in a Job Scheduler (above lollipop)

There's a nice tutorial about it here:
