If you need more classes or the android manifest comment below and i edit the post.

I already have the login.php to connect to the database at the file manager and everything.

If you can help me understanding why this error is showing up i would be gratefull.

`this error shows up:` Where does it show up? Where did you see/find it? — greenapps, Feb 22 '18 at 14:33
??????????? What is a run tab? And can we see that corner? What are you expecting? And who is putting that error message there? — greenapps, Feb 22 '18 at 14:35
at the bottom of android studio you have the TODO tab and at the left of TODO tab you have the Run tab — Dimitri Putin, Feb 22 '18 at 14:37

You should have told us at the start of your post what this error -status code- means. And further if you understand the error and what you would like to do with it. — greenapps, Feb 22 '18 at 15:33
it is at the beggining of the post i just want to login into the app but after putting my information and clicking the login button nothing happens i checked everything and what i found was the error that is specified above i don´t know how the error works so i´m asking for somebody to teach me how to fix — Dimitri Putin, Feb 22 '18 at 15:44
if you can explain me why this error is showing up i would be thankfull. — Dimitri Putin, Feb 22 '18 at 15:46
i read a post about it but i still dont understand so i'm not going to talk about what i dont know — Dimitri Putin, Feb 22 '18 at 15:55
What does 301 mean? I gave you a link where you can find the meaning of all http status codes. So why dont you use it? — greenapps, Feb 22 '18 at 15:56
You dont have to understand it at the moment. You should only tell us what you found for 301 in that document. — greenapps, Feb 22 '18 at 16:00
just found the answer it was because my domain is protected and i was trying to access the http not the https — Dimitri Putin, Feb 22 '18 at 16:15
i think it was because i changed the domain from http to https while i had the code of the login in the same file manager and it admited that the url changed — Dimitri Putin, Feb 22 '18 at 16:21

HTTP code 301 means "moved permanently". This means the URL you're trying to reach is no longer there. I had the same problem when my site implemented SSL. They redirected all request from http:// to https:// using an .htaccess file in the server, so the address in the Android app had to be changed accordingly, since it's not going to accept the redirection. You should change your LOGIN_REQUEST_URL variable to:

private static final String LOGIN_REQUEST_URL = "https://elabora.pt/login.php";

Hope this helps (it did solve my problem, though)

I had the same problem. Unexpected response code 301

I was using https://example.com but it was redirecting to https://www.example.com via .htaccess Changing to https://www.example.com in the app code solved my problem.

Try to open the url in the browser here you can see the exactly redirected URL copy this to your code.

You can specify a http folder in your host or sever instead of auto redirect to https when you use volley. It seems Volley can not handle https request.
