Caching gifs on a mural

Question

I am trying to make recyclerview with gifs. Everything is fine, but the mural does not cache gifs. After scrolling through the recycle lists and scrolling up again, the gifs are loaded again. I suggested that they need to be cached and downloaded a little faster. I used to use the ION library . The download was faster and had no cache problem. I had to change lib because it has some problem with gif decoding, described here here . The current solution looks like this:

//for default initial in application class 

Fresco.initialize(this);
//I have also tried to change DiskCacheConfig and ImagePipelineConfig params. 
//Without any positive result

//for recyclerview on onBindViewHolder    
GenericDraweeHierarchy hierarchy = holder.draweeView.getHierarchy();
Uri uri = Uri.parse(path);
hierarchy.setPlaceholderImage(R.drawable.img_bg);
Logger.e(check(uri) + " " + uri.toString());
DraweeController controller = Fresco.newDraweeControllerBuilder().setUri(uri)
            .setAutoPlayAnimations(true).build();
    holder.draweeView.setController(controller);

//for method which show cached uri images in imagepipeline
public static boolean check(Uri uri) {
    ImagePipeline imagePipeline = Fresco.getImagePipeline();
    return imagePipeline.isInBitmapMemoryCache(uri);
}
//... all the time log shows "false + gif url"

I have not seen any information about not caching animated images. There is information about unsupported post-processing of images for animations, but that's all about that. How to cache gifs?

, true gif.

public static boolean isImageDownloaded(Uri loadUri) {
    if (loadUri == null) {
        return false;
    }
    CacheKey cacheKey = DefaultCacheKeyFactory.getInstance()
            .getEncodedCacheKey(ImageRequest.fromUri(loadUri));
    return ImagePipelineFactory.getInstance().getMainDiskStorageCache().hasKey(cacheKey)
            || ImagePipelineFactory.getInstance().getSmallImageDiskStorageCache()
                    .hasKey(cacheKey);
}
