Facebook android: passing facebook object between activities

问题

I want to make an application that user will login in one activity with a button which call facebook login thing from facebook_android_sdk and I want to send a wall post in second activity which comes after user logins. I want to pass facebook object between activities. I tried serializable and parcelable, but didn't work ! Can someone guide me for this ? Thanks anyway

回答1:

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
}

Use Shared preference for passing session between the activities.

bundle.putSerializable();

Session class implements Serializable
