Вопрос:
Мое приложение для чата работает нормально, но когда я отправляю любой файл PDF или документа, он успешно загружается в хранилище и базу данных firebase. Но когда я пытаюсь загрузить файл, он выдает сообщение об ошибке No Activity found для обработки намерения.

Комментарии:
1. Опубликовать подробный журнал ошибок.
2. Если приложение выходит из строя, происходит трассировка стека. Пожалуйста, посмотрите это на logcat и добавьте его в свой вопрос.
3. Пожалуйста, проверьте сейчас
4. Есть 13 строк
messageViewHolder.itemView.getContext().startActivity(intent);, не могли бы вы указать, какая из них сбой?5. Строки № 197 и 317 адаптера сообщений.
Ответ №1:
Первое решение
URL-адреса должны начинаться с HTTP:// или HTTPS://
Итак, проверьте, правильный ли ваш URL-адрес для загрузки.
Второе решение
Попробуйте добавить это в манифест
