Каков рекомендуемый способ использования широковещательного приемника

Question

У меня есть широкоэкранный приемник, и, как показано, он содержит много зарегистрированных действий. мой вопрос заключается в том, что является рекомендуемым способом обработки таких широковещательных приемников, которые содержат множество действий? Должен ли я отделить их в отдельном файле? или положить их в службу?

пожалуйста совет.

обновление:

в случае я должен отделить приемник в другой файл, как я могу получить обновленные уведомления от него, и как я на основе обновленного уведомления выполнить действие, ölike отключения Например, кнопка «в основной деятельности»?

Лучше вы положили в отдельный один файл. Создайте уникальный метод для каждого.

Но если в конкретном действии есть долгое задание, оно должно быть на службе или потоке.
