При инициализации b как intent.extra существует несоответствие типов. Хотя b имеет тип Bundle? и intent.extra не принимает значения null, а также Bundle не может быть нулевым.
Пожалуйста, предложите решение для этой проблемы. Приложение продолжает падать, когда установлено на телефон Android и готово к запуску.
Следующий фрагмент кода, присутствующий в теле кода, показывает только предупреждение, но в конечном итоге приводит к сбою приложения только при запуске.
