AWS/Android Невозможно вычислить хеш md5

Question

Я настраиваю программу Amazon S3 Uploader для моих нужд. После создания ведра я загружаю на него видео.

PutObjectRequest por = new PutObjectRequest(buckets.get(0).getName(), Constants.VIDEO_NAME, new java.io.File(filePath)); 

Когда я запускаю линию выше я вернусь исключение ниже:

Unable to calculate MD5 has: /storage/....../bla.mp4: open failed: EACCES (Permission Denied)

OS = 4,4/KitKat, Device = Nexus 4

Что происходит?

Answer 1

Из KitKat вы не можете читать внешнее хранилище без разрешения.

Answer 2

Не быть похожим на меня. Убедитесь, что файл существует до загрузки на S3.
