First, Let’s see what shared Prefences are.
1.Shared Preferences allows activities and applications to keep preferences or data.
2.If you have a relatively small collection of key-values that you'd like to save, you should use the SharedPreferences APIs. A SharedPreferences object points to a file containing key-value pairs and provides simple methods to read and write them.
3.Shared preferences only store Primitive data types like Integer, String, Double , Float or Boolean. If you want to store object type data please consider SQLite database.
4. Shared Preferences is persistent which means it stores data into disk of android phone. So that even if the app get closed the data still remains stored and ready to use.

This tutorial is focused on How to Save Variables in SharedPreferences.
