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

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)
DAVdroid
- 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:

Everyone here is irrationally focused on the authenticity of the remote server. Android cert handling SUCKS. So… You don’t have any choice. Reread the code. Add to it… Don’t forget Subject Alt Name. Check the hyperlink I gave here for more fuel to “get the job done.” All public internet services are already compromised (e.g. The Lavabit case already proves that the remote servers… e.g. Google, et al,… are already compromised. The Public CAs controls your keys. Most people here don’t even know how the keys work – it’s magic.) CONCLUSION: Private CAs are the ONLY certificates that can be trusted. I’m tired of all the dribble about MITMs. That requires a HIJACK – “perps” need to hack your DNS, set up a fake server, set up fake certs, etc. PRIVATE SYSTEMS AREN’T WORTH THAT EFFORT. Google just gives “anyone” a copy of the keys. You don’t even have to worry about fake certs – because the certs are copies that Google gave them. People are clueless. Including coders There is nothing more dangerous than transmitting your password in the clear. “Discussing the obvious” for 8 months is not “working together on the issues.” There is only one issue: Encryption that is easy to use without a graduate degree in operating systems and crypto.

Just long-tap an address book or calendar or task list. This will also delete your collection on the server side. You don’t have to log in to your server or service to just get rid of an unwanted calendar! .
