If you add this to your Manifest for your activity you'll no longer get the scrunched wallpaper which I'm guessing you want to avoid.

<activity android:theme="@android:style/Theme.Wallpaper">

You don't need anything in your java code. Make you you don't set you layout background in your xml or set it to @null.

No way as far as I can tell. But you can always explicitly set offsets, so it does not really matter to not able to get offsets.
