title: passing the GoogleApiClient obj from one activity to another
body: <p>I want to be able to update my score for my leaderboard in a different activity other than the one that creates the GoogleApiClient obj ( the main activity ).</p>
  
  <p>What is the best way to do this?</p>
  
  <p>Is making the obj parcelable the correct way? if so how can you do it if the class is part of a library.</p>
  
  <p>Can you make the obj static? is it safe?</p>
  
  <p>Any advice on how to achieve this would be great.</p>
