A way of exporting the entire local android calendar (sometimes 'My calendar') to an iCalendar (ics) file.
It exports title, description, location, rrule, exdates, reminders and event color.
I tried following iCalendar specifications.
While my calendar app can import the generated ics-file (except the event color), I also uploaded a flow to insert the file (back) in the local android calendar.
