Я недавно перенес свой пример проекта на androidx. Но после миграции это вызывает «Render Problem» в предварительном просмотре. Тем не менее, проект запускается, но было бы полезно снова запустить предварительный просмотр.
Как указано в заголовке, проблема рендеринга вызвана "java.lang.IllegalArgumentException: java.lang.ClassCastException
at java.lang.reflect.Method.invoke ". Ниже приведен фрагмент кода.
