title: How to save user log-in state in Android?
body: <p>I'm trying to build an app with a login module. I want to save the user login state so that the end-user will not have to retype his/her credentials except if they have explicitly logged out.</p>
  
  <p>I understand that <code>SharedPreferences</code> can be of some use but I would appreciate it if some one can provide me some of their expert insight in this matter.</p>
