Разработка на Java — удалённая работа в Москве

Необходимо внести небольшие изменения в код. Необходимо изменить или на оборот доработать перый этап входа Аппка не запускается пока не выберешь камеру на телефоне, после чего загружается аппка и уже телефон запрашивает доступ к камере. Нужно: - либо убрать этап выбора камеры и назначать заднюю камеру по дефолту (соответсвенно чтоб страница запускалась с loader bar и запрос на доступ к камере, после чего инициализация камеры) - либо подключить выбор методов user и environment в соответствии с выбором пользователя, так как сейчас стоит метод environment и при выборе камеры переднего вида, включается все равно задняя var initialize = async() =>{ var unityCanvas = document.querySelector(“#unity-canvas“); var videoCanvas = document.querySelector(“#video-canvas“); window.arCamera = new ARCamera(unityCanvas, videoCanvas); window.iTracker = new ImageTracker(arCamera); try{ await window.iTracker.initialize(); console.log(“ImageTracker initialized!“); } catch{ console.error(“Failed to initialize ImageTracker.
