title: what is the Best way to use shared preferences between activities
body: <p>I have a user preference in my app, which gets used by different activities. I would like to know the best way to utilize those preferences between different activities in my App. </p>
  
  <p>I have this idea to create a shared preference object from the main activity and from there send intents to the different activities to take actions. Would that work...? </p>
  
  <p>Or just keep calling <code>getsharedpreferences()</code> from every activity..? </p>
  
  <p>Thanks.</p>
