Help :(Có ai biết làm thế nào để viết một yêu cầu POST để tải video Youtube qua API Youtube, trong Java?Youtube POST upload trong Java
Cấu trúc của yêu cầu POST cần được mô tả here.
Thật không may là tôi không thể sử dụng các thư viện máy khách Java của Java, bởi vì tôi đang làm việc trong Android, mà không hỗ trợ chúng. conn.getResponseCode() là null)
