Where can I find examples of using the usb-serial-for-android library?

Question

Android

I'm looking for an example using this library - https://github.com/mik3y/usb-serial-for-android
Namely, receiving and transmitting data, the whole Google has turned upside down and found nothing sensible.

Answer 1

Using the Usb Serial for Android library and still incomprehensible
But I'm still looking further!
