how to make a request for a list of users with predicate?

I have program-chat, and me need that i can see list, i can see all users in the list except me

Hi Vladyslav,

You can exclude your own User by using where clause in request, like “where objectId != ‘<my_user_object_id>’”. Here is the documentation for REST: (you can switch to any other SDK in the upper right dropdown on the doc page).

thank, but if another user comes, he also did not have to see yourself on the list, I do not really understand how to do it. And how to display their data in list: login, email and picture? Array?

When you do Backendless.UserService.login(), you receive a BackendlessUser object, from which you can retrieve objectId. Use it in whereClause.
