Answer 1

Try this,

1. You can get the accesstoken from the first valid session.

    String token = session.getAccessToken() 

   Then save this in sharepreferences.

2. Then before you procceed with other functions, read the stored session is check weather the session is not null and is open.

    if(session.isOpened()) { //proceed }
