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?

Edit

Exposing the LruCache

  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 flushLruCache(){ mCache.evictAll();};
            public void putBitmap(String url, Bitmap bitmap) {
                mCache.put(url, bitmap);
            }
            public Bitmap getBitmap(String url) {
                return mCache.get(url);
            }
        });
    }

I'm trying to access it with ImageLoader.ImageCache flush = (ImageLoader.ImageCache) mImageLoader;

I can't access it though.

LruCache has the method evictAll(), you could just expose this method in your ImageLoader subclass to clear the cache.

  • I'm having a bit of trouble accessing the new method, I've edit my code above, have I exposed it correctly. – JTK Apr 14 '15 at 18:33
