Android: How can I programmatically draw text on key guard screen / lock screen?

Question

Is there a way to draw on or modify the key guard wallpaper programmatically?

It looks simple enough for the home wallpaper, you can use WallpaperManager. But how about for the lock screen wallpaper? I would like to draw some text there.
