AsyncDrawable.Loader

By default this library does not render any of the images. It's done to simplify rendering of text-based markdown. But if images must be supported, then the AsyncDrawable.Loader can be specified whilst building a SpannableConfiguration instance:

final AsyncDrawable.Loader loader = new AsyncDrawable.Loader() {
    @Override
    public void load(@NonNull String destination, @NonNull final AsyncDrawable drawable) {
        // `download` method is here for demonstration purposes, it's not included in this interface
        download(destination, new Callback() {
            @Override
            public void onDownloaded(Drawable d) {
                // additionally we can call `drawable.isAttached()`
                // to ensure if AsyncDrawable is in layout
                drawable.setResult(d);
            }
        });
    }

    @Override
    public void cancel(@NonNull String destination) {
        // cancel download here
    }
};

// `this` here referrs to a Context instance
final SpannableConfiguration configuration = SpannableConfiguration.builder(this)
        .asyncDrawableLoader(loader)
        .build();

There is also standalone artifact that supports image loading out-of-box (including support for SVG & GIF), but provides little to none configuration and could be somewhat not optimal. Please refer to the README of the module.
