Oh, sorry, yes, it helped and it is fixed.
I did not look much in the FAQ for this since the error clearly pointed to the app source code and an NPE
how can I download the calendar-data from my GMX-online-calendar to my smartphone??
__the background of my question:
for month DAVdroid synchronized my calendar-dates with GMX with no problems.
Yesterday DAVdroid gave me an error-message like “server is not available”.
I tried to open the gmx-calendar manually in my laptop-firefox-browser. but i got an message like “ups, something went wrong”
OK - there seems to be an problem with the GMX server.
But now my smartphone-calendar is empty !!!
But the online GMX-calendar is all right.
I want to download the calendar-data to my smartphone. But what exactly does “synchronize” mean?
who is the boss? my smartphone or the online-gmx-calendar?
i am afraid to lose my calendar-data !!!
thanks for any hint !!!
I learned how to back up the GMX-calendar in an ics-file.
and the i dared to click “kalender neu erkennen” (“re-recognize calender”?)
now everything is fine
it would be great, if the manual would be easier for non-technicians like me.
