Android – how do I do it, user login or Facebook SDK 4.0.1
•
Android
I'm using Facebook's new SDK 4.0.1 because when I change the login button to log out, the same button is used to log out without any code. But actually I want to do some coding when I log out. So how can I distinguish these two things in the SDK? How do I declare a logout method?
resolvent:
You can check when the token changes. If the new access token is empty, the user has just logged out
new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken newAccessToken) {
if (newAccessToken==null)
//your code here!
}
};
