I have been looking for how to use a RatingBar in notification for a long time now , but as long as i know , RatingBar is not among RemoteViews even though in API 31 some widgets and layouts are added as : CheckBox , RadioButton ,RadioGroup, Switch , add to that the existing ProgressBar but according to the
documentation descendants of these classes are not supported.
So , my question is , how google map has done it since a long time ago ?
