Android share image URL with Facebook SharePhotoContent

Question

I'm trying to share a photo using Facebook's new SharePhoto & SharePhotoContent classes in the new SDK. I'd like to use an image URL instead of a locally stored image.

I am able to share an image using a locally stored drawable resource:

Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.carrots);

SharePhoto photo = new SharePhoto.Builder()
                   .setImageBitmap(image)
                   .build();

SharePhotoContent content = new SharePhotoContent.Builder()
                                .addPhoto(photo)
                                .build();

shareDialog.show(content);

But when I try to use an image URL :

SharePhoto photo = new SharePhoto.Builder()
                       .setImageUrl(Uri.parse("http://s3-ak.buzzfed.com/static/images/public/verticals/food-title.png?v=201504021353"))
                       .build();

all I'm seeing is a blank post in the Facebook shareDialog.

Has anyone else tried this and gotten it to work?

Many thanks!

What I did was download the image and get the bitmap from the server and then post to FB:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    FacebookSdk.sdkInitialize(getApplicationContext());

    Button btn = (Button)findViewById(R.id.btn_share);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getImage();
        }
    });
}

private void getImage(){
    new DownloadImgTask().execute("http://url.com/1.jpg");
}

private void postFB(Bitmap bm){
    SharePhoto photo = new SharePhoto.Builder().setBitmap(bm).build();
    SharePhotoContent content = new SharePhotoContent.Builder().addPhoto(photo).build();
    ShareDialog dialog = new ShareDialog(this);
    if (dialog.canShow(SharePhotoContent.class)){
        dialog.show(content);
    }
    else{
        Log.d("Activity", "you cannot share photos :(");
    }

}

private class DownloadImgTask extends AsyncTask<String, Void, Bitmap>{

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap bm = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            bm = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return bm;
    }

    protected void onPostExecute(Bitmap result) {
        postFB(result);
    }
}
