Chapter 2, pg 82. "R.layout.main" Error

Hi, I am currently on page 82 in chapter 2, the "Communication between fragments" exercise:

In the Main Activity, the book instructs you to enter the following code:

Code:

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

I have a problem with the last line, it says that "main cannot be resolved or is not a field" and I don't understand the error,

Update
Fixed the problem, basically I didn't think, I changed the setContentView so that it actually referenced my activity as it had the wrong name

Thanks very much,

Nick

check that the activity name is actually main, in the new java the default name is something like MainActivity or something like that
