Cannot connect to https with HttpURLConnection

Question

I try to make a GET/POST to http://www.android.com/ like in the example given in the documentation

In the InputStream I get a message saying 302 Moved and tells me to go on https://www.android.com/

When I modify my URL to https, I get:

java.io.FileNotFoundException: https://www.android.com/

HttpsURLConnection con;
String request = "https://www.android.com/";
URL url = new URL(request);
    con = (HttpsURLConnection) url.openConnection();
    con.setDoOutput(true);
    con.setInstanceFollowRedirects(false);
    con.setRequestMethod("GET");
    con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    con.setRequestProperty("charset", "utf-8");
    con.setRequestProperty("Content-Length", Integer.toString(postDataLength));

Update

I thought it was an issue of SSL certificates, but it is not. I've added a function that will blindly trust all SSL certificates. Sources here and here.

You should cast to `HttpsURLConnection` instead of `HttpURLConnection` — Titus, Dec 01 '17 at 11:17
I tried to declare as `HttpsURLConnect` and cast too, but same issue. — BeGreen, Dec 01 '17 at 11:50

He solved his problem by checking his URL and setting `con.setDoOutput(true);`. I've already made this — BeGreen, Dec 01 '17 at 12:32

Once I had the same problem which solved when I used HttpsURLConnection Instead of HttpURLConnection.
