Picasso library stopped working today with facebook graph picture links

问题

In my app i use Picasso library to load images from urls. It is a nicely working easily importable and usable library, and just do the thing i need.

However, today it stopped working, and not while developping it is stopped working on a compiled apk.

So after i searched and searched for the reason i just found this buggy thing:

I use facebook graph urls to load profile pictures.

Here is one like: profile pictre,

the link is actually "http://graph.facebook.com/1464090949/picture?type=large"

But it is redirecting to: https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn1/t5.0-1/572518_1464090949_1222130273_n.jpg

Of course, both of url calls working in a browser, and you can see the profile picture.

However when i test both links with Picasso:

    ImageView iv = (ImageView)findViewById(R.id.imageView1);

    //Url1 NOT working, loads nothing.
    String url1 = "http://graph.facebook.com/1464090949/picture?type=large";

    //Url2 is the same as URL1, i just copied it from a browser, and this is working
    String url2 = "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn1/t5.0-1/572518_1464090949_1222130273_n.jpg";


    Picasso.with(this).load(url2).into(iv);

So the conclusion is, facebook maybe changed something and from now on Picasso cannot load images from graph.

Anybody can suggest me something to make this work? Of course i can try different libraries but if there is an other way i would be really happy.

Workaround1:

Change to https from http.

Working: https://graph.facebook.com/1464090949/picture?type=large

Not Working: http://graph.facebook.com/1464090949/picture?type=large

Workaround2:

Found soulution on this topic.

If you want for example: http://graph.facebook.com/1464090949/picture?type=large

This profile picture you could use:

https://graph.facebook.com/1464090949/?fields=picture.type(large)

Which returns a JSON Object:

   {
   "id": "1464090949",
   "picture": {
      "data": {
         "url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn1/t5.0-1/572518_1464090949_1222130273_n.jpg",
         "is_silhouette": false
      }
   }
}

And tada! There it is. url's key is the redirected url you can use to load your images.

(This will need oAuth which i didnt tested, just stick with Workaround1)

Try this. worked for me perfectly

Dependency: compile 'com.squareup.okhttp:okhttp:2.5.0'

Picasso.Builder builder = new Picasso.Builder(mContext);
        builder.listener(new Picasso.Listener() {
            @Override
            public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
                /*holder.getIvSpeakerPicture()
                        .setImageDrawable(context.getResources()
                                .getDrawable("your drawable id"));*/
            }
        });
        builder.downloader(new OkHttpDownloader(mContext));
        builder.build().load(image).into(viewHolder.image);

In case you're using Amazon AWS CloudFront just like me, you can visit this page for detailed instructions from Amazon on how to set up your URL forwarding.

At the least, for Picasso to work with your redirected URLs, your URLs must support https. That is. https://yourdomain.com should redirect to https://yourAWScloudfrontdomain.net
