Error when using loopj: "Trust anchor for certification path not found."`

Question

Currently I am working on a project, on which I need to GET/PUT data from a web server with basic authentication on Android.

I followed the instructions of http://loopj.com/android-async-http/ but I encountered

"Caused by: java.security.cert.CertificateException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found."`

The method on the website above is to make use of HttpClient which is deprecated now. I know there is HttpURLConnection, but I cannot find a suitable tutorial for my purpose.

One of the issues with Android is that libraries can go out of date in quickly. The particular library you are using (loopj) has not been updated for more than 2 years so you might run into more trouble with it. Since you're just starting out it might be better to try one of the more up-to-date libraries like Volley or Retrofit rather than investing your time in `loopj`. Then if there is an issue with self-signed SSL certificates and so-on it will be easier to get support. — David Rawson, May 18 '17 at 06:43

Answer here: Http Basic Authentication in Java using HttpClient?

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64Encoder.encode ("test1:test1");

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch(Exception e) {
            e.printStackTrace();
        }

    }

}

Thanks for your reply. This solution also have the problem mentioned in the question if I replace the url with my own url. "Trust anchor for certification path not found". How to solve this. And for"String encoding = Base64Encoder.encode ("test1:test1");", can I use "String encoding = Base64.encodeToString ("test1:test1".getBytes(),0);" instead? — Xie Jihui, May 18 '17 at 06:25
