Well i'm actually having the same issue but with my Xiaomi 9C device. Not sure if I can actually do this with a Xiaomi device, but as it's an android device I'm pretty sure it's possible. I've tried all of the above posible soutions but none of them working so far. I can't even find the way to run Android Studio, as if it was not already installed. As far as I know, I've installed all the required SDK for Unity and Android Studio, but nothing seems to work for me. Any thoughts?
