Android : how can I get feed of any facebook user in android app

I'm writing app for android and i want to get feed of any user from facebook. I have an id of some user but he is not logged in my app and he doesn't give me a permissions. Can I do it? I'm using Graph Api and request -> id/feed . And another questions Can I get a feed of user after when he : 1. Log in 2. Give me a permissions (read_stream) 3. Log out. Can I read his feed after he is logout using request id/feed? Thanks )
