Я пытаюсь использовать viewpager в моем приложении, которое использовало androidX, но оно показало мне ошибку ERROR: Failed to resolve: viewpager Affected Modules: app после добавления implementation 'android.viewpager:viewpager:1.0.0' и синхронизации проекта Gradle.Я много искал, но не нашел решения. Пожалуйста, помогите заранее. Есть файл XML.
