Load Gif without animating it in 4.0

Hi, I'm using Glide 4.0 RC1 and I dont know how to load a gif stopped at first with this version. At first, I only need the first frame of the gif. When I click on it, I want to animate it. And when the loop completes 3 times, I want to stop it and show a play button again. So I need to listen somehow when the loop ends.
I load my gif normally, and when onResourceReady() is invoked, I call resource.stop(), but it start playing the gif anyway.

My code looks like this:

RequestOptions options = new RequestOptions();
options.diskCacheStrategy(DiskCacheStrategy.AUTOMATIC);

RequestBuilder request = Glide.with(getContext()).asGif().apply(options)
.listener(new RequestListener() {

@Override public boolean onLoadFailed(@Nullable GlideException e, Object model,
Target target, boolean isFirstResource) { }

@Override public boolean onResourceReady(GifDrawable resource, Object model,
Target target, DataSource dataSource, boolean isFirstResource) {

resource.setLoopCount(3);
resource.stop();
}
});

request.load(path).into(mImage);

Also, I dont know how to set a callback to be invoked when the gif finishes.

Thanks you so much.
