In what way(s) do you want to "use" the USB?

Have you searched for what Android supports via USB?

eg, https://developer.android.com/guide/topics/connectivity/usb

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

How can i pass ADC value through USB OTG ?

You're going to have to start with the Android documentation to see what it supports.

Then implement the corresponding class(es) in the STM's USB.

With USB VCP, you can send and receive any data you want.

provided Android (and the specific device/s in question) supports it!

Also a question of whether it works as Host or Device...
