Question

After adding new items in strings.xml, quite often they don\'t start working immediately in Android Studio\'s Preview.

Couldn\'t resolve res

Answer 1

you DO NOT need to close the entire project. It's just way too much for so little problem.

Just refresh the preview (click the "refresh" button)
