Subsequent to initialization, an easier way to get access to the singleton class is to * call a variant of <code>getInstance()</code>.

It also provides a simple static method * <code>checkGooglePlayServices()</code> that clients can call at an early stage of their * applications to provide a dialog for users if they need to update/activate their GMS library.
