• Coils 0.1.49rc7 and CardDAV-Sync BLOG post

Appears to support Service Discovery. But it does not perform a GET and follow the 301 redirect... it performs a PROPFIND. Is that standard?

Notes.

• The paid version syncs more fields than the free version.
• The Android 3.x platform was deliberately broken in several ways in order to push users toward use of proprietary services; one side effect of this is to use a third-party backend you also need to install a third-party contact editor. But you can easily make this your default editor. The recommended editor is "Contact Editor Pro"; either the free version or the paid version. The free version is the same as the stock editor - only with the breakage regarding third-party backends triaged.
  • The native contact editor in Android 4.x works with CardDAV backends.
• There are known issues regarding the HTC One device.
• Contact lists do not work. These appear to be deliberately broken.
• The user principal needs to be a collections. So user agent definition maps the user principal to "/dav/Contacts/"
• It requires that collection paths end in a "/".
• Requires that contact collections publish an "addressbook" resource type.

Discovery Request

Coils correctly responds to the well_known PROPFIND with a 301 to /dav/Contacts. This results in a PROPFIND of /dav/Contacts/ asking about the current user principal.

The client then sends a PROPFIND to the URL of the current user principal.

The client then displays a list of Contact folders from which to create an address book!
