This might not count as ‘integration’ as such, but in my recent app I’m passing a call to Facebook to post on a user’s wall using a URL. A few topics posted lately discuss how to open a URL using JNI so I won’t get into it, but the URL I created is something like the following:
https://www.facebook.com/dialog/feed?app_id=YOUR_APP'S_API_KEY_HERE&link=http://www.google.com&name=Your%20App%20Name&caption=I just played Your App!&redirect_uri=http://www.facebook.com
If all works correctly, when launched this will open a browser or Facebook (if it’s installed) and the user will be prompted to sign in if they haven’t, and afterward they will be served up a standard Facebook post-to-wall dialog.
My game was a port of one I did in Objective-C, and this was the only functionality it needed. I hope that this helps you.
