is there way how uniquely identify user caused event? want extract events appsactivity service, belongs specific user.
the problem is, service.activities().list() returns activities of other users of shared file, if request has set userid indicates user return activity for. returns visible activities given user , therefore contains activities of other users.
i tried filter list, seems impossible - events contains simple user object not have userid or useremail.
one way compare user's photo url avalaible in appactivity user object. note, can done if url not null, otherwise won't uniquely identify user.
