I am doing the HelloSpinner tutorial and I am getting error markers under two areas (lines 4 and 6 of the onCreate method...i marked them )and I cant figure out why? I have used the code from the tutorial and I have not varied from their instructions. Here is my code...
  package com.android.HelloSpinner;
   import android.app.Activity;
   import android.os.Bundle;
   import android.view.View;
   import android.widget.AdapterView;
   import android.widget.ArrayAdapter;
   import android.widget.Spinner;
   import android.widget.Toast;
   import android.widget.AdapterView.OnItemSelectedListener;
 public class Activity1 extends Activity {
       /** Called when the activity is first created. */
 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Spinner spinner = (Spinner) findViewById(*R.id*(<-this is an error).spinner);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, (*R.array*(<-this is an error).planets_array, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
    spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
}
public class MyOnItemSelectedListener implements OnItemSelectedListener {
    public void onItemSelected(AdapterView<?> parent,
        View view, int pos, long id) {
      Toast.makeText(parent.getContext(), "The planet is " +
          parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
    }
    public void onNothingSelected(AdapterView parent) {
      // Do nothing.
    }
}
   }////end of class Activity1
here is my main.xml file in layout
     <?xml version="1.0" encoding="utf-8"?>
     <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:padding="10dip"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content">
     <TextView
     android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dip"
    android:text="@string/planet_prompt"
/>
<Spinner 
    android:id="@+id/spinner"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:prompt="@string/planet_prompt"
  />
 </LinearLayout>
and her is my strings.xml file from my values folder
   <?xml version="1.0" encoding="utf-8"?>
