Answer 1

The SharedPreferences class provides a general framework that allows you to save and retrieve persistent key-value pairs of primitive data types. You can use SharedPreferences to save any primitive data: booleans, floats, ints, longs, and strings. This data will persist across user sessions (even if your application is killed).

You can use SharedPreferences. If you curious about the life of SharedPreferences then its clear that it will be available for entire life of your application. But keep in mind that All application storage looses data when user clears the application data, so that time SharedPreferences will also loose the value.

Instead of using db, you can use SharedPreferences.

Answer 2

you can use SharedPreferences to save variables within your application. As a example you can use SharedPreferences in a game to save the score/points. In this case if you are dealing with less number of variables i think the best way is SharedPreferences. Hope my answer helped you.
