How to save data after close activity? I didn't find it in the sample.

Settings are saved after edit it. Data is not saving when closing activity. But:

• you can create custom StorageInterface to save all data in memory;
• when activity is closeing (onDestroy, onStop, onPause) iterface may save all data in safe place;
• need to member to load data on init custom StorageInterface;
