I can not understand how to do the right to make requests to VKontakte.
VKRequest request = VKApi.audio().add(VKParameters.from("owner_id", "audio_id", ID_list.get(contex_menu_position))); owner_id - if you do not specify something, id will be taken by default, i.e. my. ID_list - ArrayList<Integer> which stores the id songs.
As a result, I get "VKError (API errorVKError (code: 100;; I’m undefined)), I’ve already tried many combinations, I’ve got 0.
