Answer 1

Use Shared Preference for that. When user logged into your application store login status into sharedPreference and clear sharedPreference when user click on logged Out.

Check every time when user enter into application if user status from shared Preference is true then no need to login otherwise move to login page.

First create class in that class write all the functions set and get shared preference information or in javascript use localStorage to set and get values probably first time login to set userinfo using:

localStorage.setItem("name","vale");

after switch off you try to open your app, at the time use localStorage.getItem("name") based on that you can load your values.
