Question regarding screen sizes

I'm working on a live wallpaper and ready to release a new version on the Android market. Last time when I tested it on a tablet (x-large) screen the images got cut off and did not scale so i want to disable support for tablets. Does anyone know how I can d开发者_JAVA技巧o that? I already changed the API level but it seems I cannot lower that anymore with newer versions.

Thanks

Take a look here. You can set supported screen sizes in your manifest.

<supports-screens android:xlargeScreens="false" />
