Add User in my andiod app : Hi I Implemented an android app.
 
1. A Splash screen 
2. Then MainActivity 
  - GetSharedPerf 
  - if(sharedpref == empty or null) { 
   * Open activity --> Login Activity 
  - }
3. else { Stay on MainActivity }

My Question is After Successful login i need to add new user 

--> add new user User Id in Shared pref & Switch between Users in MainActivity

Note: Simply I need gmail app model for add multiple user ac and switch between users inbox...
