I need to get different user follower counts through facebook graph api. I get the user id through user name but how i get the follower count of that user.
thanks in advance
You're facing at least two problems here:
1) The username field has been deprecated with Graph API v2.0
2) The /{user_id}/subscribers edge has been deprecated with Graph API v2.0
I guess you'll not be able to do what you want to achieve unfortunately.
See https://developers.facebook.com/docs/apps/changelog#v2_0_graph_api
