SharedPreferences allows activities and applications to keep preferences, in the form of key-value pairs similar to a Map that will persist even when the user closes the application. Write an Android application the uses SharedPrefences to persist and to retrieve data to/from SharedPreferences respectively as described below:

There are two EditTexts, one for name and another for email address.

There are three buttons: SAVE, RETRIEVE, and CLEAR.

The SAVE button will save the name and the email address in the SharedPreferences.
