Сбой приложения при получении уведомления FCM на переднем плане работает на фоне

Question

Я добавил Firebase Cloud Messaging в свое приложение, следуя указаниям в документации.Кажется, работает нормально, но приложение падает при получении на Foreground, но отлично работает, когда оно получает закрытие.

Хорошо, приложение получает уведомления о том, когда оно убивает и фон, но оно падает при получении уведомлений на переднем плане.

Answer 1

Просто удалите

TODO("not implemented")

TODO (...) - это функция Kotlin, которая всегда выдает NotImplementedError.Если вы хотите пометить что-то с помощью TODO, но не создавать исключение - просто используйте TODO с комментариями:

Надеюсь, это поможет !!!

Answer 2

Согласно ответу Мохита удалить TODO (...), а также удалить тип возврата: Любой из объявления функции.

Например, заменить функцию ниже,

private fun scheduleJob(): Any {
    TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}

с,

private fun scheduleJob() {
    // TODO : "not implemented"
}
