 *  Also note that passing via a bundle may be necessary to avoid accessing the

 *  preview, which can be null - see note about video resolutions below.

 *  Also see https://stackoverflow.com/questions/14093438/after-the-rotate-oncreate-fragment-is-called-before-oncreate-fragmentactivi .

 *  If the application is destroyed when in background when the user is viewing

 *  the settings, then the application and its fragments will be recreated -

 *  so reading from the bundle means the state is restored, where as trying

 *  to read camera settings won't be possible as the camera won't yet be

 *  reopened.
