The parameter can be the name of a single preference to be fetched. In this case the value of the preference is returned by the method. Null is returned if the preference is not set. The parameter can be map of preference names and values. Each preference in the map is fetched and the value in the map is set to the new value. If a preference cannot be found then the value in the map is not modified. The modified map is returned as the method value.
