Just tried it on my Samsung Galaxy S6 with Android 7 and I can confirm that the calendar entries disappear after using MAX POWER SAVING mode from Samsung. But only if I restart the device after the mode is activated. If I switch back from this mode without a reboot only the sync interval is set to manual (which is an already known bug from Samsung and can’t be fixed by us). But at least the calendars are then still there.
@Error101 you need to contact Samsung about it. It seems to be a common issue with their MAX power saving mode - people are affected in different ways by this
Ah, sorry I thought I was in the DAVdroid forum… With ICSdroid you can always set the minimum interval that you need for one calendar, the others only get updated when there are changes on the server so there is no unneeded traffic. See here because we’re often asked about it:
@jondo There is also https://play.google.com/store/apps/details?id=com.rejh.sharedr (will be FOSS and on F-Droid soon). But I prefer that one can share without having to install extra apps and the Android share facility is used, where possible.
Probably this one: https://github.com/ical4j/ical4j/issues/230
I wonder whether it works with a VTIMEZONE with both STANDARD and DAYLIGHT components… unfortunately, this would require debugging ical4j/2.x and 3.x has just been released (which is not useable with Android <7).
Re: Add reminder to event
There are some public calendars (like concerts events) that don’t have reminders and you can’t control the source, so it is impossible to set a reminder for now. For those it would be super helpful if you can set some fixed reminders (yes, more than one ideally) for all events in a particular ICS calendar. So I can set to get reminders for all concerts the day before and 2 hours before the event for example.
Those notifications should disappear as soon as the next successful sync is run, which should happen a short time after an I/O error. Can you confirm that these messages go away by themselves?
Maybe we can change them to minimum priority notifications like in DAVdroid…
update: The export from WoltLab is wrong; the last Event in the ical file is 16. May.
I guess this is caused by the “Sub-Categories” in Woltlab. I had to export each sub-category by its own to get it working.
Thank you for your help, this issue is solved.
Sadly, there is no error by manual sync. Is there any logfile written by the app I may provide?
Already tried to wipe data and reinstalled from F-Droid store.
Here are some random images that may give you more information.
Seriously, I have no clue what is wrong:
