setContentView(R.layout.main); error when start new project
<p>I'm just starting to develop with android, and a followed a tutorial on google to get everything set up. I'm using eclipse and I have both the android sdk and the eclipse plugin installed, but when I create a new Android Project, I get an error on this line from the start.</p>

<p>my code :-</p>

<pre><code>package khalid.app.fm;

import android.app.Activity;
import android.os.Bundle;
import android.R.*;

public class RadioBlancoFMActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}
</code></pre>
