What is the proper usage of the menu.addIntentOptions()?

I don't understand the correct usage of menu.addIntentOpt开发者_高级运维ions()

The best example would be the contact manager. If you install ZXing Teams Barcode Scanner, open a contact in your contact manager and open the menu then you will get an option to generate a QR code for that contact.

This could of course also be another software doing just that for you as it simply represents a hook for software able to do that. You can define such options yourself with that method and of course you can define an application which would perform a certain action yourself.
