@thefinnomenon how can I do the same with android?

@sagark1510
Not really sure on the Android side but I would just grep for a similar debugger-proxy string and edit it the same as I did here.

@thefinnomenon Yeah I know about http/s default ports, I think what me in 2017 meant was, why hardcoded, but this makes no sense either, so no idea what I wanted

@samermurad haha fair enough. I can't even remember writing this tbh
