推荐答案

保存您的令牌，并通过SharedPerferences到期，然后在第二个活动创建新的Facebook对象，设置标记和共享preferences过期，检查的有效性。就这样！ 教程并在此示例：

Save your token and expires via SharedPerferences, then create new Facebook object in second activity, set token and expires from SharedPreferences and check validity. Thats all! Tutorial and here sample:

//facebook token and expires
SharedPreferences prefs = getApplicationContext().getSharedPreferences("facebook",
            MODE_PRIVATE);
String access_token = prefs.getString("access_token", null);
long expires = prefs.getLong("access_expires", 0);
if(access_token != null) {
   facebook.setAccessToken(access_token);
}
if(expires != 0) {
   facebook.setAccessExpires(expires);
}
if (facebook.isSessionValid()) {
// Do your work here
}
