what does R.id.snack do in Radio Button example?
<p>In the Developer.Android example <a href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/RadioGroup1.html" rel="nofollow">here</a> what does the <code>newRadioButton.setId(R.id.snack);</code> do? </p>

<p>In these examples they use variable names that are suppose to help the learner infer what it does. So why did they choose to call it a snack here? 
Did they call it a snack to try to lead me to think of it as a radio hint?</p>

<p><strong>Edit</strong> Found out they are calling it a 'snack' only because the previous example used food themed variables</p>
