Firebase Analytics Filter By User ID

Question

The Firebase Android SDK for analytics provides a method named setUserId(String id), now i enabled firebase logging and every time i called the method setUser

Answer 1

I have spent a few hours on this and found the answer i was looking for more or less, hopefully this might save someone else some time.

The only way to filter by Firebase's User Id property is by creating an audience, there you will be able to pick the user id property that is supplied from the setUserId(String id) method.

It is a downer though because you won't see any events for the user/user's you want from before the audience was created.
