            The contacts permissions have been declared in the AndroidManifest for Android M  and
            above only. They are not available on older platforms, so we are hiding the button to
            access the contacts database.
            This shows how new runtime-only permissions can be added, that do not apply to older
            platform versions. This can be useful for automated updates where additional
            permissions might prompt the user on upgrade.
