How to run an Android program on a Linux server and communicate with it from another program?

Question

linux

I want to run an android program on a Linux server and be able to communicate with it from outside, that is, from another program, for example, a python script. That is, to run an android program on a Linux server, I use BlueStacks, this android application runs inside it. And it turns out something like:
python_script <-> BlueStack <-> android_app
But what's next? How can I communicate with this program from a python script? How to get through BlueStack? BlueStack doesn't have api at all, right? But, even if there was, after all, the api should also be in the prog itself on android, right?
In short, is it even possible?
update :
And if the program on android is not mine, then it definitely won't work if it doesn't have an API, right? That is, on my own I can still screw it somehow .....

Answer 1

Use GenyMotion(VirtualBox), it creates a network interface and has ip.

Answer 2

No.
BlueStack is an android sub-emulator designed for games that cuts everything that can be cut so that the games work. He's no good for anything else.
