How to force a cache clearing using Universal Image Loader Android?

Question

I am using UIL to load images in a listview.

When I long press an image in the listview, I show a dialog to modify that picture, replacing it with a new one using t

Answer 1

I think you should delete cached image in memory cache when opening dialog. Use MemoryCacheUtil for that:

MemoryCacheUtils.removeFromCache(imageUrl, imageLoader.getMemoryCache());

Answer 2

If you are caching it both in memory and disc, for example:

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext())         
        .memoryCache(new UsingFreqLimitedMemoryCache(2 * 1024 * 1024)) 
        .discCache(new UnlimitedDiscCache(cacheDir)) 
.........

Ensure you remove it from both of them, then reload your image view.

MemoryCacheUtils.removeFromCache(url, ImageLoader.getInstance().getMemoryCache());
DiscCacheUtils.removeFromCache(url, ImageLoader.getInstance().getDiscCache());

Answer 3

This should work:

imageLoader.clearMemoryCache();
