问题
I am working on an application that need to login with facebook. This is the first time when i am integrating Fb API in my application. I have start from Getting Started with the Facebook SDK for Android & successfully get fb access_token.
There are three Activitie in my application & what i need to manage is to have logged in user's Profile Image & name on all these Activities when user successfully get login using facebook.
I know, i can query fb GraphAPI & get complete profile data of current logged-in user using access_token. I succeed to get profile data of user by using valid access_token using_https://graph.facebook.com/me?<access_token>&format=json
I need the profile image of login user as well(which need user's fb_id)http://graph.facebook.com/<fb_id>/picture?type=large
Is it possible to get user's profile image using access_token?

Finally, after a long search, i got the way to access login user's image by using only access_token
https://graph.facebook.com/me/picture?access_token=<your_access_token_here>
thanks to @Jess for your valuable answer!

You don't need an access token to retrieve a user's profile image. Just issue a http GET request on http://graph.facebook.com/YOUR_ID_HERE/picture, so for example:
http://graph.facebook.com/4/picture gets you user id 4's picture, no access token needed.
EDIT:
To fetch the picture without knowing their fb id but with their access token, just execute a GET request on /me?fields=name,picture and you will receive a response with the URL to their profile picture.
See Graph API Tool example:
https://developers.facebook.com/tools/explorer/?method=GET&path=me%3Ffields%3Dname%2Cpicture

So after messing around with the facebook graph apis for a bit, I have found that you can get the profile pic in two ways:
Use this as the profile pic url by substituting the user id: https://graph.facebook.com/USER_ID/picture?return_ssl_resources=1
Using the access token: https://graph.facebook.com/me/picture?access_token=ACCESS_TOKEN
Hope this is helpful.
