R error at the start of Android project

Question

I have started a new application project in android and I am getting this strange error on R file.I have done many projects but this is for the first time that an R error is coming as R file is generated automatically.There is no error in my xml or class files as I have just started the project.This is what its showing-:

    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
        }
R cannot be resolved to a variable.

I tried creating the R class but it shows up in src folder and not in gen folder.Please help me out here anyone.Thanks in advance.

in your project R.java file is not created due to any error in your any xml file. I'm correct?? — Preet_Android, Apr 10 '13 at 07:07

Check your Java compiler version, it should be 1.6.

Check the problems tab in eclipse IDE, it must be showing some errors.

otherwise clean and build.

Also check Build Automatically option in project menu.
