Is it possible and easy to re-adapt an android application into a web resource / application?

Question

Android

The next abstract problem.
There is, let's say, some abstract, exclusively touch-adaptive application for the Android OS. That is, everything is touched, touched, scrolled, and all these delights-moving fingers, styluses are carried out on the fly, conveniently, quickly, usably.
Is it possible to actually implement the idea of ​​this application also but on the web? That is, just simply make a service that would open in a browser on tablets / phones and you could do the same in it, touch, touch, scroll and all these delights, movements with your fingers, styluses to carry out the same way as it was in the mobile version applications on Android.
Well, actually, if you open this service in touch devices, you can use your fingers with styluses, if you open it on a desktop, then you can just move everything at least with a mouse.
Can this be done with modern web technologies? How hard will it be?
How laborious will it be to implement such a service from scratch on the web if there is a detailed technical specification, design, business model?

Answer 1

As far as I understand the android application interface is written in Java. Website interface in JavaScript. There is no automatic transfer and never will be. You can most likely use some libraries from the application on the server.
Labor costs - from 1 day for an abstract game of tic-tac-toe (rewrite from scratch) to infinity
