Check if Image is in Cache - Universal Image Loader

Question

I guess the title says it all. I tried:

imageLoader.getMemoryCache().get(key); 

with the image uri as key, but it always return null

I think you can create a simple method in your utility class like this:

public static boolean isImageAvailableInCache(String imageUrl){
    MemoryCache memoryCache = ImageLoader.getInstance().getMemoryCache();
    if(memoryCache!=null) {
        for (String key : memoryCache.keys()) {
            if (key.startsWith(imageUrl)) {
                return true;
            }
        }
    }
    return false;
}

and Use it like:

   if(Utils.isImageAvailableInCache(imageUrl)){
//
      }
