What's entityId on getLikes function?

[reixa00]

Taken from the sample app, what's that entityId value? How can I get it?

String entityId = "14104316802_522484207864952";
SimpleFacebook.getInstance().getLikes(entityId, new OnLikesListener() {
    @Override
    public void onComplete(List<Like> response) {
     }
});
