title: Load Firebase remote config in Application class
body: <p>Since Application is known for its global-variable usage. I was thinking maybe it's good to load Firebase remote config in onCreate() method in Application class and all variable will be stored as "public static" and with an initial value.</p>
  
  <p>Just want to know if it is a good idea because I've tried to store remote-configs as private objects with classic getter/setter and that causes null-exceptions frequently.</p>
