Maybe it would be nice to indicate on the web site that davdroid is limited to VCard 4.0 support only (for now) and will not work with VCard 3.0 servers like DAViCal.
It would save you some time reading and closing bugs about this known limitation.
If at least one contact has at least one relationship specified, the app crashes whenever it syncs. There’s a “RELATED” field in vCards so this should not happen, as far as I know.
Can’t reproduce that issue with CyanogenMod Android 4.4.4. Please provide detailed steps to reproduce (what relation to enter etc.).
Duplicate of #547?
Please check whether this issue is still present with DAVdroid 0.8.1.
I guess this was a duplicate of #547, so I’ll close this issue now. If this problem happens for DAVdroid 0.8.1+, please post here again.
