Java Local Development Environments Advanced Tooling Refactoring

Can't refactor "private Queue<Song> mSongQueue;" in IDEA

When I try to do the first step in the video and refactor "private Queue<Song> mSongQueue;" in IDEA. I click Refactor this > Type Migration and then I get the warning "Only fields, variables, method parameters or methods of valid type can be considered." and I can't proceed. I've copied all the project files from the download zip. What's going on?

Your post says "private Queue mSongQueue;" Isn't the Queue supposed to have a type? Like this:

private Queue<Song> mSongQueue

if that was just a typo, are you selecting the Queue part before refactoring? I may need to go look back at the video.
