How to synchronize your Google Contacts and Calendars using DAVx5 on Android

Since version 4.3.4.1 DAVx5 provides an option to connect to Googles CardDAV and CalDAV API via OAuth. So you can synchronize your Contacts and your Calendars from the Google Cloud without any Google Play Services on Android. **Important: After having done the steps from the video, you additionally have to switch your OAuth app from "Testing" to "Production" mode in the API & Services → OAuth Consent Screen. Otherwise your token will expire after 7 days and you need to re-authenticate in DAVx5. You don&have to actually request verification (create videos, send infos to Google etc).** Credits: Music by Lesfm from Pixabay:
