Question

Answer 1

A:

The implementation of that function is going to be entirely dependent on the data you are trying to save. You basically just need to create a data structure that contains all of the information you want to be saved, and return that from onRetainNonConfigurationInstance.

Sketchy example: Your page has a person entering a name and address.

public class LoadedData {
   private String name;
   private Adddress address;
   ...
}

public LoadedData collectMyLoadedData() {
  LoadedData data = new LoadedDate();
  data.setName(myNameTextBox.getText());
  ....
  return data;
}

The timing and method for saving state described there is different from the one you mention in your question. onRetainNonConfigurationInstance is designed to save large amounts of state only on a configuration change like screen orientation. saveInstanceState is used more generally when the activity lifecycle causes the activity to be killed and restarted.
