title: Wrapping SharedPreferences with Dagger 2 and RxJava2
body: <p>Do I need to wrap the Android <code>SharedPreferences</code> class or not? If yes, can you please provide me a simple working example? </p>
  
  <p>I know how to use the <code>SharedPreferences</code>, but when it comes to wrapping it and providing it with Dagger 2 and RxJava2 I am confused.</p>
