Everything in my code seemed fine when I left it. The next time I went on, the android:icon value in AndroidManifest.xml said mipmap wasn't a resource so I kept the string blank. Next thing you know Android Studio couldn't find the R resource file and an error popped up into the FunFactsActivity.java file. Can anyone please tell me what to do?

Try clean and rebuild the project.

Build > Clean Project, wait to finish, Build > Rebuild Project.

If doen't work, check if in the FunFactsActivity has some import like this:

import br.com.leandro.meutempo.R;
