I need to get list of users:
I do not want to wait for the download of entire list.
I want to get user one by one.
how can I do that?
If you just want to convert
Observable<User>, you can use
getUsers().flatMapIterable(l -> l).
If you want to downloads and process the user list one by one, you need to change your API, since
Observable<List<User>> getUsers() won't emit anything until the whole list is downloaded.
