How to log in to the site through android?

Question

Android

I want to download the page code in the Android application, the whole problem is that you must first go through authorization in order to get the desired page (quite banal?).
I want to understand how this all works. Should I use a separate stream or what? How to carry out authorization in general, I read a lot that some POST requests are used? How to sort it all out? Where to begin?

Start by looking for similar questions on the toaster. The topic has been brought up 100 times.
In short - put a sniffer on your computer, see what requests go to the site during authorization (get / post, parameters, etc.) and repeat these requests in your program.
About a separate thread - not at all in the topic of authorization, but yes, all asynchronous operations (and communication with the server is a vivid example of such an operation) must be done strictly in a separate thread.
