Hello,
You can access Users table via Backendless.Data API as an ordinary table.

More about data retrieval:

https://backendless.com/docs/android/data_general_api.html

Map-driven approach (you will receive a list of Maps (Users)):

DataQueryBuilder queryBuilder = DataQueryBuilder.create();
queryBuilder.setPageSize(100);
Backendless.Data.of("Users").find(queryBuilder, new AsyncCallback<List<Map>>() {
           @Override
            public void handleResponse(List<Map> response) {
                System.out.println(response);
            }

            @Override
            public void handleFault(BackendlessFault fault) {
                System.out.println(fault);
            }
        });

OR class-based approach (List of BackendlessUser objects):

DataQueryBuilder queryBuilder = DataQueryBuilder.create();
queryBuilder.setPageSize(100);
Backendless.Data.of(BackendlessUser.class).find(queryBuilder, new AsyncCallback<List<BackendlessUser>>() {
            @Override
            public void handleResponse(List<BackendlessUser> response) {
                System.out.println(response);
            }

            @Override
            public void handleFault(BackendlessFault fault) {
                System.out.println(fault);
            }
        });

As you can see DataQueryBuilder is used to set pagesize 100 (number of returned Users). Otherwise default value is 10. In order to get absolutely all objects in Users table - you nextPage(method of query builder) OR read this article to create Codeless service which will retrieve all objects from a table with 1 call from client-side
