* <p>Demonstrates required behavior of saving and restoring dynamic activity
* state, so that an activity will restart with the correct state if it is
* stopped by the system.</p>
*
* <p>In general, any activity that has been paused may be stopped by the system
* at any time if it needs more resources for the currently running activity.
* To handle this, before being paused the
* {@link android.app.Activity#onSaveInstanceState onSaveInstanceState()} method is called before
* an activity is paused, allowing it to supply its current state. If that
* activity then needs to be stopped, upon restarting it will receive its
* last saved state in
* {@link android.app.Activity#onCreate}.</p>
* <p>In this example we are currently saving and restoring the state of the
* top text editor, but not of the bottom text editor. You can see the difference
* by editing the two text fields, then going to a couple different
* applications while the demo is running and then returning back to it. The
* system takes care of saving a view's state as long as an id has been
* assigned to the view, so we assign an ID to the view being saved but not
* one to the view that isn't being saved.</p>
