title: setVisibleActivities undefined
body: <p>Ever since upgrading to Android SDK API 19 (KitKat), I'm getting the following error when trying to build my project:</p>
  
  <p><code>
  The method setVisibleActivities(String, String) is undefined for the type PlusClient.Builder
  </code></p>
  
  <p>If I look at <a href="https://stackoverflow.com/q/16800732/276949">this question</a>, it has a link to the API where apparently this function was documented - but it appears to have simply disappeared from there as well.</p>
  
  <p>Here is the code in question:<br>
  <code>
              PlusClient mPlusClient = new PlusClient.Builder(this, this, this)
              .setVisibleActivities("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity")
              .build();
  </code></p>
