Может кто поможет. Дело в ограничениях запущенных с Android Oreo (API 26). Пытаюсь добиться следующего: при свернутой активности отслеживать изменения системного буфера обмена (например копирование адреса страницы), а далее с помощью моего приложения уже обрабатывать данный текст взятый из буфера (например вывести в toast на экран). Если компилирую код на старые API до 26, то всё работает, а вот на свежих версиях приложение вылетает в ошибку. Ниже мой код.
