====== About the script ======
  * Purpose : set the background color of an item with colors extracted from the wallpaper
  * Author : Pierre Hébert

====== How to use the script ======
Make sure you run Lightning v12.4b2 or newer.

Import the script and set its "Item menu" flag. Long tap on an item, select Action -> Scripts and tap on this script.

This is a sample code demonstrating the use of the Android Palette API. It will compute colors asynchronously and use the result.

====== Script code ======
<sxh javascript>
LL.bindClass("android.app.WallpaperManager");

try {
    // extract the wallpaper bitmap
    var wp = WallpaperManager.getInstance(LL.getContext()).getDrawable();
    var bitmap = wp.getBitmap();
    
    Palette.generateAsync(bitmap, {
         onGenerated: function(palette) {
            var item = LL.getEvent().getItem();
            var ed = item.getProperties().edit();
            var box = ed.getBox("i.box");
            box.setColor("c", "n", palette.getMutedColor(0));
            box.setColor("c", "s", palette.getLightMutedColor(0));
            ed.setString("i.selectionEffect", "PLAIN");
            ed.commit();
         }
    }).execute(null);
} catch(e) {
e.printStackTrace();
    // no bitmap or OOM
}
</sxh>
