title: storing shared preferences for different types of users on android studio
body: <p>I am trying to develop an android app which has 2 login &amp; 2 registration forms ( 2 for users and 2 for shops).The launch activity is the user's login page.
  my question is how to store 2 shared preferences so that if i was already logged in as a user, it will redirect me to user's main page, and if already logged in as a shop, it will redirect me to shop's main page. 
  thanks.</p>
