Я получаю ошибку NoClassDefFoundError с моим приложением. Использую dns java, okhttp3 и retrofit. Мой минимальный API - 19.
Я читал, что пакет java .time был добавлен в API 26. Означает ли это, что я не могу использовать dns java для Android API ниже 26? Или что-то другое вызывает эту ошибку (например, прогард)? Может ли помочь более старая версия dns java? Мне не удалось найти никакой информации о минимальном API dns java.
Изменить: я нашел это на странице dns java Github.
Переход с версии 2.1 .x в v3
Методы, использующие java .util.Date, устарели. Используйте новые версии с java .time.Instant или java .time.Duration вместо
Значит ли это, что я могу использовать версию 2.1.x?
