ActivityType
The integer in ActivitiesCache.db that says what an activity row records: 5 opened, 6 in focus, 10 clipboard content, 16 copy or paste, 2 notification.
ActivityType is a column of the Activity and ActivityOperation tables. Researchers have mapped the common values: 5 an app, file or page opened; 6 an app in use with focus time; 10 clipboard content; 16 a copy or paste operation; 2 a notification (kacos2000). Other values relate to system settings or remain unexplained.
The type decides how to read the rest of the row, including which payload keys to expect. See ActivitiesCache.db activity types and payload fields.
