there are 2 possible ways:

1) you need to overwrite in on create AccessTokenTracker like this:

accessTokenTracker = new AccessTokenTracker() {
            @Override
            protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken,
                                                       AccessToken currentAccessToken) {
                    if (currentAccessToken == null) {
                        //write your code here what to do when user logout
                    } 
                }
            }

2) You can call LoginManager.logOut() to log out the user

hope this will help you :)
