Why does 9-patch does not work on wallpapers?

Question

I had a small image 250x208 (size decreased from 960x800) and made 9.png out of it. Set it as a wallpaper image via wallpaperManager.setResource(R.drawable.my_wallpaper); but it is still getting stretched incorrectly like this is not 9-patch image.

Why 9-patch does not size correctly as a wallpaper?

What do you do when you have an app that has to set some image as a wallpaper?

Thanks in advance

Are you talking about the wallpaper on the homescreen? or a background for the layout in your application? — FoamyGuy, May 26 '11 at 17:46
Wallpaper on the mobile desktop, home screen. like live wallpaper, but just a regular wallpaper — sandalone, May 26 '11 at 17:51

I don't believe that WallpaperManager supports nine-patches, so you may need to render the nine-patch yourself using a live wallpaper.

EDIT: removed since the question was changed.

~~You should just use a View with an android:background set to the nine-patch. There's no need to use an ImageView with all its fancy custom image scaling logic for a background image.~~

Can I set/install Live Wallpaper programmatically? I set this wallpaper from withing the Android app. – sandalone May 29 '11 at 14:23

No, I don't believe there's *currently* a mechanism to set a Live Wallpaper programmatically. – Roman Nurik May 30 '11 at 16:21
@RomanNurik, will plain png files get scaled as well or only 9patches exclusively? – Vass Feb 22 '12 at 14:23
