You can try this: 

WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);
Drawable drawable = getResources().getDrawable(R.drawable.newimage);
Bitmap wallpaper_source = ((BitmapDrawable) drawable).getBitmap();           
try {
    int w = wallpaperManager.getDesiredMinimumWidth();
    int h = wallpaperManager.getDesiredMinimumHeight();
    int x = (w-wallpaper_source.getWidth())/2;
    int y = (h-wallpaper_source.getHeight())/2;
    Bitmap wallpaper = Bitmap.createBitmap(w, h, Config.ARGB_8888);
    Canvas c = new Canvas(wallpaper);
    c.drawBitmap(wallpaper_source, x,y, null);
    wallpaperManager.setBitmap(wallpaper);
} 
catch (IOException e) 
{
    e.printStackTrace();
}

WallpaperManager wallpaperManager = WallpaperManager.getInstance(activity);
    BitmapFactory.Options myOptions = new BitmapFactory.Options();
    myOptions.inDither = true;
    myOptions.inScaled = false;
    myOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
    myOptions.inDither = false;
    myOptions.inPurgeable = true;
    Bitmap preparedBitmap = BitmapFactory.decodeResource(activity
            .getApplication().getResources(), R.drawable.newimage, myOptions);
    try 
    {
        wallpaperManager.setBitmap(preparedBitmap);
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    }

This is what I use to make my images scale well without crazy lines running across - you could try this for wallpaper - not sure if it works , let me know.
