Android : Flush Universal Image Loader cache

I'm using a volley singleton to load images

 private VolleySingleton(){
        mRequestQueue = Volley.newRequestQueue(VolleyApplication.getAppContext());

        mImageLoader = new ImageLoader(this.mRequestQueue, new ImageLoader.ImageCache() {
            private final LruCache<String, Bitmap> mCache = new LruCache<String, Bitmap>(10);
            public void putBitmap(String url, Bitmap bitmap) {
                mCache.put(url, bitmap);
            }
            public Bitmap getBitmap(String url) {
                return mCache.get(url);
            }
        });
    }

I need to flush the cache to update the imageView when the photo is changed.

I've read about MemoryCacheUtils here but can't seem to implment it in my code, can I use MemoryCacheUtils in my code? if not is there a way to flush the cache in my imageLoader?
