What kind of view is the Google Pay popup?

Issue

How Google Pay opens up a payment sheet as bottom popup (see image bellow) and communicate with the website to notify when payment is done?

Is it a deeplink using scheme such as googlepay://... or an Intent using iframe as defined here? Or it's something else.

I'm wondering if this kind of popup can be displayed by any application for other purpose.

Solution

It is a BottomSheetDialogFragment, and yes you can use it in your application. Read this article for more
