Почему okhttp3.Interceptor не работает?

Question

Я добавляю два Inteceptors и NetworkInceptor в OkHttpClient, но работает только cachingInterceptor. Я не знаю, как добавить другого Interceptor для изменения заголовков запросов.

И есть изображение, показывающее, что мои заголовки запроса не были изменены под кодом.

Использование addInterceptor, не addNetworkInterceptor.

Вы почти всегда хотите приложение Interceptor, а не сетевой перехватчик.

Сетевые перехватчики вызываются только тогда, когда запрос попадает в сеть, а не для попадания в кеш.
