You can use one of two apps to set up a CardDAV account on your Android device: CardDAV-Sync free beta and the paid app DAVdroid. There are setup directions for both apps below, but we recommend DAVdroid for easier synchronization and more robust support.
CardDAV-Sync free beta Setup
Once you've installed CardDAV-Sync free beta, do the following on your Android device:
Tap Settings. Select Accounts. Tap Add Account. Select CardDav. Under Add account tap CardDAV again. For URL enter mail.hostedemail.com. For Username enter your email address. For Password enter your email password. Tap Next. Once your information has been verified, tap Finish. Your webmail contacts will now appear in the contacts app along with any groups. Any changes made in webmail will show up on your device with a refresh.
DAVdroid Setup
Once you've installed DAVdroid, do the following on your Android device:
Tap Settings. Select Accounts. Tap Add Account. Select DAVdroid. Select Login with URL and email address. For URL enter mail.hostedemail.com/carddav/youremailaddress. For Username enter your email address. For Password enter your email password. Tap the arrow on the top right to verify your account details. Select your address book to sync all the contacts.
