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

Answer 1

Sometimes, when using the Universal Image Loader library, there comes a time where the loader takes a while to verify whether the remote image has been already loaded in your cache. To load the cache file directly, you can use the following method to check whether a local copy of the remote file has already been made:

    File file = imageLoader.getDiscCache().get(url);  
 if (!file.exists()) {  
      DisplayImageOptions options = new DisplayImageOptions.Builder()  
      .cacheOnDisc()  
      .build();  
      imageLoader.displayImage(url, imageView, options);  
 }  
 else {  
      imageView.setImageURI(Uri.parse(file.getAbsolutePath()));  
 }
