I have researched many things about jsoup, examples and everything, but I can not log in to this site .

I created an app as a login screen but I do not know how to do the post from my app to the site and get the page to where it is redirected

When I click on it it sends a request to "aluno.cefsa.edu.br/Login/Login" through a post

Could someone help me make the application request from the app to the site
