How do I push a wallpaper to android?
<p>I am in an operating systems course that centers around hacking up android phones. I want to set my friend's wallpaper to something amusing but benign. Sadly, our test phones does not have wireless drivers on them. Any idea of how I can adb push something in? </p>

<p>Is there a wallpapers directory I can place things in, for instance? </p>
