Где я должен добавить Admob Id к этим кодам?

Question

Я новичок в программном обеспечении. Я получил приложение, и файл конфигурации приложения не существует. Мне нужно добавить мой Admob Id вручную. Я думаю, что это файл, который я нашел для этого, но я не знаю, где его добавить. Заранее спасибо за помощь.

Буду признателен, если вы мне покажете. нужно ли добавлять их отдельно для всех размеров объявлений?
