Answer 1

All you need to do is to replace 'import android.support.annotation.Nullable' in class imports to 'import androidx.annotation.Nullable;'

Thats a common practice..whenever any import giving issue...remove that import and simply press Alt+Enter on the related class..that will give you option to 'import class'..hint Enter and things will get resolved...
