How to properly prepare a socket server for an Android application?

Question

Android

1) Is it true that an Android application can send requests to an external server only via the http protocol, and cannot send requests via ws and wss. For example wss://example.ru

2) If the first statement is true, then how are socket requests to the server built, and how the server should process them. How can you connect to sockets via http request in general?

For example, using JS from a browser, you can connect to a socket server in the following way: How is this done in an Android application?
var socket = new WebSocket("ws://example.ru/ws");

Answer 1

1. No, not true. You can send not only via HTTP, but also via HTTPS, WS, WSS
2. Your first statement is not true.
Connecting via websocket is best done through a library, for example, OkHttp
