Anybody knows why this code won't compile?

Code:
package com.leebrainlow.tween;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        final Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				
				Animation anim = AnimationUtils.loadAnimation(Main.this, R.anim.animation);
				b.startAnimation(anim);
				
				
			}
		});
    }
}
