Syncing with Android

Android does not support CalDAV or CardDAV protocols out of the box. To sync your Davnode data, you need to install a synchronization adapter app. We recommend DAVx⁵ (formerly DAVdroid), widely considered the best solution for Android.

​
Server Settings

You will need these details during the setup:
ServiceServerPortEncryption
CalDAV/CardDAVmail.davnode.com443SSL/HTTPS

​
1. Install DAVx⁵

  1. Download and install DAVx⁵ from the Google Play Store or F-Droid.
  2. Open the app and grant the necessary permissions (Contacts, Calendar, and Tasks).
    Note: For the best experience, also grant the “OpenTasks” permission if you plan to sync tasks.

​
2. Configure Account

We recommend to always use an app password for connecting calendars and contacts.
  1. Open DAVx⁵ and tap the + (Plus) button (or “Add Account”).
  2. Select Login with URL and user name.
  3. Enter the following details:
    • Base URL: https://mail.davnode.com/
    • User Name: Your full Davnode email address.
    • Password: Your Davnode password.
  4. Tap Login.
  5. DAVx⁵ will connect to the server and discover your available address books and calendars.
  6. Create Account:
    • Enter an account name (e.g., “Davnode”).
    • Tap Create account.

​
3. Select Data to Sync

  1. After creating the account, you will see a list of available collections.
  2. CardDAV: Tap the CardDAV tab and check the box next to your address book.
  3. CalDAV: Tap the CalDAV tab and check the boxes next to the calendars you want to sync.
  4. Tap the Sync icon (refresh arrows) in the bottom right corner to perform the initial sync.

​
4. View Data in Android Apps

Once DAVx⁵ is synced, your data will appear in your native apps:
  • Contacts: Open your default Contacts app. You should see “Davnode” (or the name you chose) listed under Accounts/Groups.
  • Calendar: Open your default Calendar app (e.g., Google Calendar). Go to the sidebar menu and ensure the checkboxes for your Davnode calendars are ticked.

​
Troubleshooting

​
Sync Not Working Automatically

Android aggressively kills background processes to save battery. If contacts or calendars stop updating:
  1. Open DAVx⁵.
  2. Go to Settings > App info.
  3. Ensure Battery Optimization is set to Unrestricted or “Don’t Optimize” for DAVx⁵.

​
”Certificate Not Trusted”

If you receive an SSL error:
  1. Ensure the URL is entered correctly as https://mail.davnode.com/.
  2. Ensure you are not behind a restrictive firewall or VPN blocking port 443.
