Is there a class called ColorWheel created in the project. If yes, check if both these classes are defined in the same package. For me, in the package 'com.teamtreehouse.funfacts', the following classes are defined:

ColorWheel FactBook FunFactsActivity

Sorry what does " check if both these classes are defined in the same package " mean i am new to this so help me out please thanks

Try opening the Fun Fact project in Finder and open the folders under app -> src -> main -> java.

All of the directories under the java are called packages ( For example - com.teamtreehouse.funfacts). Open each sub package and make sure the following java programs exist.

ColorWheel.java FactBook.java FunFactsActivity.java
