title: Android: onRetainNonConfigurationInstance() deprecated?
body: <p>Inside my Activity I am instantiating an object which is responsible to query, process and store the data needed by the fragments. I was about to use <code>onRetainNonConfigurationInstance()</code> in order to retain the object after configuration changes, but I just realized the method has been deprecated.</p>
  
  <p>I can see that the new recommended way is to use Fragment's <code>setRetainInstance()</code>, but it doesn't look like it's what I need, because my object doesn't deal with just 1 fragment.</p>
  
  <p>Do you have any suggestions?</p>
