res/ directory tree

I'm going 开发者_C百科through some book which tries to teach android development. In the book, the author outlines some of the directories found under res/. He mentions res/menu which holds XML based menu specifications. He also makes mention of res/raw which holds "general-purpose files." These folders were not created when I created a new android project. I'm using the latest Android SDK with the latest Eclipse version. Are those folders he mentions from some older version of the android SDK?

You create those folder's when you need them, they aren't automatically created. If you create a folder in res called raw, ant will pick it up and use it accordingly.

You really dont need them, but if you do decide to use them, just create a new folder and call it that, it will work fine.
