Error in Eclipse When Opening new Android Project

I get two errors on the problems tab before I make any modifications. Both are for this;

R cannot be resolved to a variable

On lines 12 and 18 of MainActivity.java .

I'm using the SDK supplied in the teachers notes (Windows 64 bit)

This is in the "src" directory, not the "res" directory. But shows up as an error regardless.

Help?

Yes. I have the windows 64 bit android platform installed.

After poking around online, the problem may be related to "R" not being created under the "gen" folder.

Which step do you believe I may have missed?

I ended up just switching over to Android Studio to progress in the lessons. Wasn't able to get Eclipse to generate the R file.

Hi James,

Have you read the "Teacher Notes" yet on the video page here? I think it might solve some of your problems.
