Android to server 500 error

Question

I am trying to send user informations to server via open connection and it returns user id in JSON. Everything is OK but when i am trying to read user id with getInputStream i can't read it (i take 500 server error). When i try it with getErrorStream and log the result the JSON is come here. Why ? How can i overcome it ?

Answer 1

This is not the answer, try using this code and share the result, the code is not tested but if the server response is correct this could be works, else, verify your server.

PD: In test use this plain code, any additional property or doInput/output is not required

package com.test.test;

import java.io.BufferedInputStream;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

class receiveResponse {
    String Response(String name, String urrl, String longi, String lat)
            throws IOException {
                String url = "http://185.22.184.103/project/connection.php?name="+URLEncoder.encode(name, "ISO-8859-9")+"&url="+urrl+"&long="+longi+"&lat="+lat;
        URL link = new URL(url);
        HttpURLConnection conn = (HttpURLConnection) link.openConnection();
        conn.setConnectTimeout(10000);
        conn.setReadTimeout(10000);

        BufferedInputStream is = new BufferedInputStream(conn.getInputStream());

        int ch;
        StringBuilder sb = new StringBuilder();
        while ((ch = is.read()) != -1) {
            sb.append((char) ch);
        }
        is.close();
        return sb.toString();
    }
}
