title: Where is the cache folder of the Universal ImageLoader?
body: <p>The caching of my Universal ImageLoader seems not working. I'm wondering where the folder of the cache is. I found there is a folder in my sdcard:</p>
  
  <p>data->data->id of my app->cache->uil-images</p>
  
  <p>But it's empty. Here is my code:</p>
  
  <pre><code>        DisplayImageOptions displayOptions = new DisplayImageOptions.Builder()
                  .cacheOnDisc(true)
                  .cacheInMemory(false)
                  .showStubImage(R.drawable.img_placeholder)
                  .showImageForEmptyUri(R.drawable.img_placeholder)
                  .showImageOnFail(R.drawable.img_placeholder)
                  .bitmapConfig(Bitmap.Config.RGB_565)
                  .displayer(new FadeInBitmapDisplayer(500))
                  .build();
  
          ImageLoader imageLoader = ImageLoader.getInstance();
          imageLoader.init(ImageLoaderConfiguration.createDefault(this.context));
          imageLoader.displayImage(imgUrl, imageView, displayOptions);
  </code></pre>
  
  <p>No matter I set the cacheInMemory to false or true, the result is the same. Can somebody explain what could be wrong with it? Thanks.</p>
  
  <p>By the way, I'm using universal imageloader 1.8.6</p>
