Question

I saw this question: The session has been invalidated because the user has changed the password while I was searching for an answer for the very same question, but I don’t know how to make the session longer for android so could someone tell me how. I think that just those two lines must be changed :

String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);

But I don’t have any idea how must they be changed

Answer 1

As it’s mentioned in a reference:

Step 8: Extending the access token

With the deprecation of offline_access, you need to extend your
access_token every time a user opens your app. To do this, call
facebook method extendAccessTokenIfNeeded in your application’s
onResume() function:

public void onResume() {
super.onResume();
facebook.extendAccessTokenIfNeeded(this, null);
}

Note: Make sure you have the latest android SDK available at
