i am a new in facebook application.
i will make a server(google app engine) and client(android application).
As a facebook perspective, both my server and client are acutally client.
Anyway, server and android application both need login.
is there something to login both (server and client) only in a one action??
in conclusion, i want a way to login two client, using only one login action.
After logging in a user you are given an access token. You could share this token between both your applications, al long as they use the same facebook app (app-secret and app-id).
