Application crashes after adding a RadioGroup in Mark L. Murphy's "A Fancier Form" tutorial
<p>I'm going through the "A Fancier Form" chapter in Mark Murphy's "Android Tutorials" book (1st edition) and I can't get past step#2: Add a RadioGroup. The application compiles and installs on emulator and phone with no errors but when I try to run it I get the:</p>

<p>Sorry!
The application LunchList
(process apt.tutorial) has
stopped unexpectedly. Please try
again.</p>

<p>This is the code from the book (the only code that changes in that section is the RadioGroup part):</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;TableLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:stretchColumns="1"&gt;
  &lt;TableRow&gt;
    &lt;TextView android:text="Name:" /&gt;
    &lt;EditText android:id="@+id/name" /&gt;
  &lt;/TableRow&gt;
  &lt;TableRow&gt;
    &lt;TextView android:text="Address:" /&gt;
    &lt;EditText android:id="@+id/addr" /&gt;
  &lt;/TableRow&gt;
  &lt;TableRow&gt;
    &lt;TextView android:text="Type:" /&gt;
    &lt;RadioGroup android:id="@+id/types"&gt;
      &lt;RadioButton android:id="@+id/take_out" android:text="Take-Out" /&gt;        
      &lt;RadioButton android:id="@+id/sit_down" android:text="Sit-Down" /&gt;
      &lt;RadioButton android:id="@+id/delivery" android:text="Delivery" /&gt;
    &lt;/RadioGroup&gt;
  &lt;/TableRow&gt;
  &lt;Button android:id="@+id/save"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:text="Save" /&gt;
&lt;/TableLayout&gt;
</code></pre>

<p>Help please?</p>

<p>Thanks,
