How to make a POST request in Android using JSoup or similar library/function?

Question

Android

Hello, I am new to Android programming. Now I'm trying to make a small application that will change the user's mood in the Ya.ru social network. According to the page from the API, you need to create a request like this:

POST /person/{uid}/post/ HTTP/1.1
Host: api-yaru.yandex.ru
Content-Type: application/atom+xml; type=entry; charset=utf-8
Content-Length: 199
Authorization: OAuth vF9dft4qmT

<entry xmlns="http://www.w3.org/2005/Atom" xmlns:y="http://api.yandex.ru/yaru/">
    <category scheme="urn:ya.ru:posttypes" term="status"/>
    <content>Новый статус</content>
    <y:comments_disabled/>
</entry>

But I don't understand how to do it at all!
I'm trying to make a request like this:

Connection.Response res = Jsoup.connect(src.attr("href")+"?oauth_token="+Main.getToken()).method(Method.POST).execute();

which should refer to the specified page, but I don’t know how to put Content-Type, type, charset, content-length, authorization field, category scheme and everything else there.
Help me please.

jsoup.org/apidocs

org.jsoup
Interface Connection
To get a new Connection, use Jsoup.connect(String).
header(String name, String value)
Set a request header.
data(String key, String value)
Add a request data parameter.
method(Connection.Method method)
Set the request method to use, GET or POST.

try {
      Connection conn = Jsoup
          .connect("http://4pda.ru/forum/index.php?act=Login&CODE=01");
      conn.data("PassWord", "password");
      conn.data("UserName", "username");
      conn.method(Connection.Method.POST);
      conn.referrer("http%3A%2F%2F4pda.ru%2Fforum%2Findex.php%3F");
      Response resp = conn.execute();
      System.out.println("statusCode: " + resp.statusCode());
      Document doc = conn.url("http://4pda.ru/forum/index.php?").get();
      System.out.println(doc.select("div.user_home").text());
    } catch (IOException e) {
      e.printStackTrace();
    }
