Dealy in wallpaperManager.setBitmap (bitmap)

I am trying to change wallpaper using a widget. I use the code below to achieve that: But there is an certain delay every time the code is executed.

Is there any way to avoid this delay. 

...
WallpaperManager wallpaperManager = WallpaperManager.getInstance (context);
Bitmap bitmap = BitmapFactory.decodeStream (new FileInputStream (file));

//here @file is fetched from a phone storage

wallpaperManager.setBitmap (bitmap);
...

I see four options which might help here:

  1. Reduce the size of the bitmap before saving it to the file
  2. Preload the bitmap (well, if possible)
  3. Do all this asyncronous
  4. Make sure your heap is as empty as possible before loading the bitmap. If android has to free heap while decoding a large bitmap it will slow down noticeably
