Hello. I have purchased Davdroid and it correctly connects to my calendar / contacts within its own application.
However, I cannot find a Calendar App that supports CalDav. I have downloaded many and they all only seem to support Google Cal.
Does the group have any suggestions for an Android Calendar / Task app that will display my synced data. For the record, I am using SOGo as my server solution.
Looking forward and hopeful.
