Titanium: How to hide the actionBar in a non-Alloy project?

Question

I have no problem hiding the action bar in an Alloy project. However, how do I do this in a non-Alloy project?

I tried this:

win.activity.actionBar.hide();

But it doesn't work.

<android xmlns:android="http://schemas.android.com/apk/res/android">            
    <manifest>
        <application android:theme="@style/Theme.AppCompat.Translucent.NoTitleBar.Fullscreen"></application>
    </manifest>
</android>

Add this to TiApp.xml
