Always do complex operations on worker thread or use AsyncTask as in

In your Adapter add below class

static class ImageLoader extends AsyncTask<>{
  private ImageView shop_image;
   ImageLoader(ImageView shop_image){
      this.shop_image = shop_image;
    }
 ..
   public Bitmap doInBackground(){
          return Bitmap.createScaledBitmap(BitmapFactory.decodeFile("" + shopImageFile),
                        100, 100, true);

   }

   public void onPostExecute(Bitmap thumbnail){
     shop_image.setImageBitmap(thumbnail);
                Utilities.setEmptyError(business_name_layout);
                setImageMargins(shop_image);
    }
 ..
}

In Bind Holder method

new ImageLoader().execute();
