Automatically collected events
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.
Event name | Triggered... |
---|---|
ad_click | when a user clicks an ad Publisher events coming from AdMob via the Google Mobile Ads SDK |
ad_exposure | when at least one ad served by the Mobile Ads SDK is on screen |
ad_impression | when a user sees an ad impression Publisher events coming from AdMob via the Google Mobile Ads SDK |

adunit_exposure | when an ad unit served by the Mobile Ads SDK is on screen |
app_clear_data | when the user resets/clears the app data, removing all settings and sign-in data |
app_exception | when the app crashes or throws an exception |
app_remove | when an application package is removed or "uninstalled" from an Android device This event is different from the Daily uninstalls by device and Daily uninstalls by user metrics, which are both reported by Google Play Developer Console. The app_remove event counts the removal of application packages, regardless of the installation source, and the count changes depending on the date range you are using for the report. The Daily uninstalls by device and Daily uninstalls by user metrics count the removal of application packages only when they were installed from Google Play, and are reported on a daily basis. |

app_store_subscription_convert |
when a free-trial subscription is converted to a paid subscription (Android only) This event is set as a default conversion. Requires an initial subscription that was made on or after July 1, 2019.
