Parse - About sessionToken and be logged in to few devices at the same time from the same user

There is a way to login to the same user from different devices? I have an Android app and web app and I want to be able to be logged in for both apps at the same time. I'm getting error 209 "invalid session token" when logged in at the second app(web or android). I'll glad to get some information about that error and how can i solve my problem. Thanks!
