@executive Do you use Horde? Which server do you use?
The URL given in “REMOTE RESOURCE” points to the iCalendar that contains the invalid line. You can enter the URL in a browser (same credentials as for CalDAV) and check.
If you’re not sure, please just send this thread to the server admin and tell us what they say.
About CalDAV/CardDAV servers (including setup and configuration), other clients (mobile/desktop) and related software (like Android calendar and contact apps)
Afaik there is no software that allows you to sync with x servers and concurrently with x clients and keep everything in sync. You can only have one server for a “server wins” architecture. Ofc there is the possibility of mirroring or clustering on the server side but with 2 different types of servers (fruux and NC for instance) this would not be possible for various reasons.
Hm, it’s reliably reproducible here using the Android emulator and testing different Android versions (8.1 and 9.0).
I’ve attached a logcat.txt from a failing test run. logcat.txt
Maybe that helps in finding the cause of the failure.
Ah. I didn’t address the moving window part. All I can think is sent data includes a scankey code to Grab Window. I use XFCE and it has ALT + Right-Mouse-Drag to move a window. I’m not sure how that would be fixed.
Additionally, while you are frustrated, try to refrain from cursing or swearing when asking for help.
