кто-нибудь знает, почему InputStream responseBody = conn.getInputStream(); дает мне ноль?
в принципе, ошибка здесь в первых нескольких строках кода.У меня есть спокойная API-ссылка XML, которую я пытаюсь проанализировать как объект JSON.
И logcat не очень полезен.Любая помощь будет принята с благодарностью
спасибо
