For Facebook Android SDK 4.x you have to use the "AccessToken.getCurrentAccessToken()" as said by @Diljeet but his check didn't work for me, I finally checked it by doing:

Activity "onCreate":

facebookAccessToken = AccessToken.getCurrentAccessToken();

To check if the session is still active (I made it in the "onResume" method but do it where you need):

  if(facebookAccessToken != null){
        sessionExpired = facebookAccessToken.isExpired();
  }else{
        sessionExpired = true;
  }
