Fullscreen Activity in Android?

Question

How do I make an activity full screen? I mean without the notification bar. Any ideas?

Answer 1

I wanted to use my own theme instead of using @android:style/Theme.NoTitleBar.Fullscreen. But it wasn't working as some post on here had mentioned, so I did some tweaking to figure it out.

In AndroidManifest.xml:

In styles.xml:

Note: in my case I had to use name="windowActionBar" instead of name="android:windowActionBar" before it worked properly. So I just used both to make sure in the case I need to port to a new Android version later.
