title: Authenticating an android App to a Rails 4 API
body: <p>I'd like to build an API for other partner Android Application but at the time this api would be a web app, so the user can login via the android app and web app. I've manage sessions using the rails session[] hash, but when i tried to access from a node js application that I'm using for test it doesn't keep the session, i guess it's for the cookies. </p>
  
  <p>I was reading about devise, but i don't really understand it... I need some  way to login, and retrieve data from the android device without sending the user id and the password each time a pull a request. </p>
  
  <p>What would be the best way? Should I go with devise?... </p>
  
  <p>Thanks in advance.</p>
