R error at the start of Android project [duplicate]

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?? — Gurpreets11

Check your Java compiler version, it should be 1.6.

Clean and build your project. This will generate R.java to you auto generated files folder.

Delete your R.java which is created under your src directory and then do clean and build.

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.
