Android: приложение не загружает файл в Firebase ⇐ JAVA

[Anonymous]

У меня проблема. Приложение Android загружает аудиофайл в Firebase, но приложение не загружает контент.
У меня есть эти коды:
UploadSong (этот код контроллера ввода:< /p>

И если я выберу файл с помощью средства выбора аудио и процесс загрузки пройдёт успешно, то вот результат:
Размер файла в Firestore: 8,7 КБ, в то время как в эмуляторе : 5,06 МБ
Я пытался загрузить на физическое устройство, но результат тот же. Логарифм пишет следующее сообщение: Загрузка прошла успешно.
Я пытаюсь загрузить файл, но Firebase не получает его содержимое. Пожалуйста, постарайтесь мне помочь!
