645 PointsThe code fragment you pasted uses classes that are not accessible by imports in new context. Not sure what happened.
The above message appeared when I tried to paste the code from the FunFact to the FactBook. It wants me to select a class to import to the new file. They give the choice java.util.Random

Just check that from the link here IntelliJ Auto Import

32,885 PointsYou need to import java.util.Random It's required for the project. If that's not your problem, please elaborate and I'll help you out!

14,483 PointsDuring simple refactoring, you would have copied the section along with the Random declaration from FunFactsActivity file into a new file called FactBook. It was a simple copy paste procedure. However, when you did that and ran the program, the class FactBook lost track of Random class since it was not imported like it was in FunFactsActivity file. For Random to be used we have to implicitly import it. Rest Ratik's answer is completely justified else if its some other reason as pointed out.

645 PointsI guess my big confusion is that when Ben copied and pasted the same code, he did not get this warning. I studied the video and did exactly the same thing. What would be the difference? Still do not understand. Just a note: this is my first ever app class.

14,483 PointsWhen Ben copy pasted the code from one file to the other intelliJ (thus Android Studio) was smart enough to import the Random file itself.
Maybe its an IDE issue. Are you Eclipse or Android Studio?

1,635 PointsI have the same problem and java.util.Random automatically placed the import for me. Still got the errors.

3,329 PointsI had this issue too, so I checked the forum to see if this was something I needed to correct before moving on. I took Ratik's suggestion to clean the project--and it appears that cleaning it deleted the FactBook class that we just created? I can't seem to find it. Rebuilding it didn't put it back, as far as I can see.
