Add a live background to an Android View (like the Twitter App)

In the official Twitter Android app, the opening activity (the dashboard) and the Tweets tab activity have a live background/wallpaper (clouds moving, etc).

How do you accomplish that?

Is it as simple as setting your view's background to a live wallpaper drawable?

And then adding <uses-feature android:name="android.software.live_wallpaper" /> to your manifest?

It's definitely not using a live wallpaper. You can create a custom Drawable or a custom View and draw the animation yourself.

Adobe AIR? Maybe?
