Error on Android class R

I don't know why, but ever I create new Android project this coming with error on Class R.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

On setContentView(R.layout.activity_main) Eclipse show me a error

R cannot be resolved to a variable

So, I try to use import android.R; but I get other error:

activity_main cannot be resolved or is not a field

Why it happen? How I can resolve this issue? And why a New Eclipse project is already coming with error?

Thanks!

Don't import android.R. You need to import your own R file from the gen folder. If your R file didn't get automatically generated for you, then check for errors in your layout XML files.
