What is Android's icicle parameter?

Question

I've noticed in some coding people use icicle with the onCreate method, and I was wondering what it is exactly:

public class About extends Activity {     @Override     protected void onCreate(Bundle icicle) {         super.onCreate(icicle);         setContentView(R.layout.whatup);     } 

Is this the same thing as savedInstanceState?

Answer 1

"icicle" is sometimes used as the name of the parameter because onSaveInstanceState() used to be called onFreeze().

Answer 2

The name isn't magic. It's just a placeholder for one of the formal parameters. As shown by the API, onCreate takes one Bundle parameter. It's up to you what to call it.
