What are Android Instant Apps: An evolution in app sharing and discovery, Android Instant Apps allows Android users to run your apps instantly, without installation. Android users experience what they love about apps - fast and beautiful user interfaces, high performance, and great capabilities - with just a tap.
I don’t believe so, without a fundamental rearchitecture of Cordova. The point of Instant Apps is that various bits of the app are split up, so you only download parts of them. Cordova is designed to package everything up into a monolithic app binary.
