i want to create an android iptv player using kotlin the problem is that the iptv apps i tried can work with different providers out of the box just by giving the url and credentials of their account in the serveur and i did not find open source projects .

i have an iptv stalker account that worked with different apps so i tried to do the authentication request using postman before doing the programming part but it did not work.
there is a lot of iptv apps but none of them is open source.
