Preference value from the SharedPreferences
. If

is true).
This may not always be called. One example is if it should not persist but there is no default value given.
Parameters | |

restorePersistedValue |
boolean :
True to restore the persisted value;
false to use the given defaultValue. |
defaultValueObj |

The default value for this Preference. Only use this
