Я надеюсь, что вы преуспеваете в этот трудный период, и вы работаете над развитием некоторых навыков,
Я работаю над мини-проектом android, у меня есть проигрыватель c, который загружает файлы пользователя musi c из локального хранилища устройства.
НО -> я хочу изменить это и настроить медиаплеер с песнями, которые у меня есть на сервере, и позволить пользователям просто наслаждаться песнями, которые я предлагаю на моем сервере.
я надеюсь Вы могли бы помочь с необходимыми изменениями, я не могу найти что-то полезное
