适用于Android的Facebook SDK：当我的Android应用发布的帖子“喜欢/评论”时，尝试获取通知

Question

I'm fairly new to Facebook SFD for Android.

What I'm trying to achieve is an Android app that uses facebook login, post to the user timeline and gets notified whenever one is commenting or liking that post.

I went thru Facebook tutorials for login and for Publish to Feed. All went well.

Now I'm struggling with the last part. I don't see how to be notified whenever there is a like or comments. I browsed the web and stackoverflow forum without any success. I'm guessing that there is a mechanism to be notified by Facebook and that I don't have to start a process just to monitor the post...
Anyone could give me a hint on the API to use?

I'm currently looking at "Creating Object Types" section Associating Actions with Object Creation ( https://developers.facebook.com/docs/opengraph/creating-object-types ) but it looks like this describes how to do for facebook web app, and not for android app.

EDIT

I've found this https://developers.facebook.com/docs/graph-api/real-time-updates/ but not quite sure how to "translate" this into Android coding. If anyone could help me with this, it would be greatly appreciated.

I guess you have to create a page in php that will handle the responses from Facebook, it starts with a

• GET response from Facebook that you retrieve with $_GET["name"] in php, and you have to send back a confirmation to Facebook to confirm that the connection works, and Facebook will send you the answer you want via

• a POST request ( $_POST["name"] ) (with a json object, containing the informations about the user in object for example, and the different updates in entry ).

You can put all these informations in a database, and when the user start your application, you can automatically connect him to a php script that check if the database has new informations for him.

(specifying who he is, with a user variable that he keeps in the memory of his device, and then you ask for informations from the database about this user ). I haven't tested, but it should work.
