Android - Clear Facebook access token

Question

I have a SettingsActivity where there are several options including finding Facebook friends and logging out. So when a user chooses to find her Facebook friend

Answer 1

in Facebook SDK v4 we can log out using

LoginManager.getInstance().logOut();

note that don't forget to initialize sdk like this

FacebookSdk.sdkInitialize(getApplicationContext());

Answer 2

private Session.StatusCallback statusCallback = new SessionStatusCallback();

logout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Session.openActiveSession(this, true, statusCallback);  
}
});

private class SessionStatusCallback implements Session.StatusCallback {
@Override
public void call(Session session, SessionState state,
Exception exception) {
session.closeAndClearTokenInformation();    
}
}

Answer 3

You should pass session variable through Parcelable interface and clear session through that session variable. Pass facebook session like this : Passing a Facebook session across activities

Answer 4

Using Facebook SDK v4 you can do the following:

if (AccessToken.getCurrentAccessToken() != null) {
    LoginManager.getInstance().logOut();
}

You can take a look at the LoginManager class.

Answer 5

Do like this

try {
Session.getActiveSession().closeAndClearTokenInformation();
} catch (Throwable e) {
e.printStackTrace();
}

Answer 6

Try this below code for session clear in facebook integration android.

Put below method in your activity and call before the login to facebook.

public static void fbClearToken(Context context) {
    Session session = Session.getActiveSession();
    if (session != null) {

        if (!session.isClosed()) {
            session.closeAndClearTokenInformation();
            //clear your preferences if saved
        }
    } else {
        session = new Session(context);
        Session.setActiveSession(session);

        session.closeAndClearTokenInformation();
            //clear your preferences if saved
    }

}

For me it's working... Hope this is helpful for you...
