6,662 PointsonCreateOptionsMenu vs onPrepareOptionsMenu
According to documentation: "If you want to modify the options menu based on events that occur during the activity lifecycle, you can do so in the onPrepareOptionsMenu() method. This method passes you the Menu object as it currently exists so you can modify it, such as add, remove, or disable items." Why are we updating states in onCreateOptionsMenu? UPDATE: so this question is actually in response to Create an Options Menu workshop by Ben Deitch. In this workshop, he mentions that whenever the state of a checkbox from the menu option is changed, we should do it within the onCreateOptionsMenu, so my question is, why not in the onPrepareOptionsMenu? Does it matter where we update, or is this more like a best practice sort of thing? I've tried it in both places, and in both cases they work.

13,833 PointsQuestion is not very well asked. But think about the flow.
onCreateOptionsMenu() is called once. onPrepareOptionsMenu() is called every time the menu opens.
