How to hide action bar before activity is created, and then show it again?

I need to implement splash screen in my honeycomb app.
I use this code in activity’s onCreate to show splash:

setContentView(R.layout.splash);
getActionBar().hide();

and this code to show main UI after sometime:

setContentView(R.layout.main);
getActionBar().show();

But before onCreate is called and splash appears, there is small amount of time when action bar shown.

How can I make action bar invisible?

I tried to apply theme to activity without action bar:

<item name="android:windowActionBar">false</item>

but in that case getActionBar() always returns null and I found no way to show it again.
