Create: 

// MY_PREFS_NAME - a static String variable like:

//public static final String MY_PREFS_NAME = "MyPrefsFile";

SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();

 editor.putString("name", "Elena");

 editor.putInt("idName", 12);

 editor.apply();

Use:

SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE);

String name = prefs.getString("name", "No name defined");//"No name defined" is the default value.

int idName = prefs.getInt("idName", 0); //0 is the default value.

editor.clear();

editor.apply(); // commit changes
