Automatically collected events are triggered by basic interactions with your app. As long as you use the Firebase SDK, you don't need to write any additional code to collect these events. To see event reports, click Events in the report navigation in Google Analytics, or click the Events tab in the Firebase console.
Analytics collects these events for Android and iOS apps unless otherwise stated.
The following parameters are collected by default with every event, including custom events you implement yourself:
- language
- page_location
- page_referrer
- page_title
- screen_resolution
