Answer 1

You can store all values in SharedPreferences in onPause, and then load them again in onResume and populate your views using that data.

Answer 2

Multiple ways to do this:

1. An SQLite database
2. Store the data as a file on the SD card.
3. SharedPreferences for the activity.
4. As a static variable in the Application class.
