[DID YOU KNOW] that DAVdroid has advanced support for vCard4?

  • admin

    DAVdroid is one of the very rare Android CardDAV apps which have advanced support for vCard4. This means that (if your server supports it – for instance, KolabNow and Baïkal do) you gain

    • native contact group support (KIND/MEMBER) without hacks
    • native support for various properties (BDAY, IMPP, etc.)
    • no more charset problems (vCard 4 is always UTF-8)


    • automatically detects whether vCard 4 is supported by the server (fallback: vCard 3)
      • detected by querying CARDDAV:supported-address-data property
    • uses vCard 4 for uploading and downloading contacts:
      • GET with Accept: text/vcard;version=4.0
      • CARDDDAV:addressbook-multiget with <address-data content-type='text/vcard' version='4.0'/>
      • PUT with Content-Type: text/vcard;version=4.0

    Sample vCard 4:
