Viewsaccess web serial api in android chrome browser
using web serial API in windows, mac os, and Linux chrome browser I can receive and send data. but in the android chrome browser, I am not able to send or receive data from a serial device.
so which API is used to read and write data to serial devices in the android chrome browser.
also, there is a polyfill serial API for android chrome but is showing an error shown in the image.

The team that built the implementation of the Web Serial API in Chromium also wrote a polyfill library which uses WebUSB to support platforms which don't provide built-in serial drivers: https://github.com/google/web-serial-polyfill
It looks like you are already trying to use this library. Can you file an issue on the library's GitHub project so the team can look at the error you're seeing?
Note, it seems like there are some Android devices which have USB serial drivers that end up blocking WebUSB from claiming interfaces even though the platform doesn't let apps actually use them. https://crbug.com/1099521 is tracking a workaround for that.
