On my codes the symbol R is red. Is something wrong?

At FunFacts.activity.java some of my codes have R but it is red.

Could you try to clean and rebuild your project to see if that clears things up? R is a special class that actually has to be created and updated before Android Studio knows that something exists there.

Every time i rebuild an erros occurs.I downloaded again, and this time the fol "build" didn't even exist.I downloaded another version and i am going to check it right now hope it works. And thanks for replying!

Stlil no build folder :(

You're downloading it from the project files section of the video attached to this question, right? Are you using Eclipse or Android Studio? When you build it, exactly what errors are you getting? When I download it and unzip the file, I do get a build folder, with the only thing in it is an intermediates folder and inside that a model_data.bin file.
