This difference makes the findviewbyid () method throw an unresolved reference error when used in the oncreate () method of a fragment. the screenshot below shows this error. Through the use of those synthetics, you can directly reference views by their ids without the need for findviewbyid. to use them you need to import them through a gradle dependency. however, that was phased out in favor of the view binding solution someone mentioned below. The most common reason you're trying to directly use a view id (e.g., mybutton.text = "hello") without explicitly getting a reference to it using findviewbyid(r.id.mybutton) or setting up view binding. this is especially true if you're coming from older tutorials that used kotlin android extensions. solution.
