how to fix this error JSON in java A JSONObject text must begin with '{' at 1 [character 2 line 1]

I have managed to save the data in the BD, but when I get to JSONobject it goes to the exception and presents this error in METHOD POST:
public int insertarCliente(Cliente c){
//globalURL += "?rut=" + c.getRut() + "&nom="+ c.getNombre() +"&app=" + c.getApellidoP() + "&apm=" + c.getApellidoM();
String globalURL = "http://localhost:60367/api/Cliente?rut=" + c.getRut() + "&nom="+ c.getNombre() +"&app=" + c.getApellidoP() + "&apm=" + c.getApellidoM();
try {
HttpURLConnection conn = Conectar(globalURL);
conn.setRequestMethod("POST");
conn.setRequestProperty("ACCEPT", "application/json");
//conn.setRequestProperty("Content-Length", "0");
conn.setDoOutput(true);
conn.getOutputStream().close();
if (conn.getResponseCode() == 200) {
InputStreamReader isr = new InputStreamReader(conn.getInputStream());
BufferedReader br = new BufferedReader(isr);
String resp = br.readLine();
JSONObject obj = new JSONObject(resp.trim());
//JSONArray obj = new JSONArray(resp.trim());
br.close();
return obj.getInt("resp");
}
} catch (Exception e) {
Logger.getLogger(ClienteDAO.class.getName()).log(Level.SEVERE, null, e);
}
return 0;
}
and presents the following error.
Grave: org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]

Consume Zimbra Get Calendar REST Api in Java

I get this error when I consume the REST Api of Zimbra on Android: must Athenticate java.lang.RuntimeException: Failed : HTTP error code : 401
at ZimbraREST.main(ZimbraREST.java:33). However I am absolutely sure that my login and my password are the good ones and my code was working perfectly fine yesterday, and I did not modify any important stuff linked to this code. This code should get me an xml file that I use to get sync calendar on my app. Thanks for your help. Here is my code:
#Override
protected Void doInBackground(Integer... integers) {
System.out.println("15email_adress=" + email_adress);
System.out.println("15password=" + password);
String dayStart = String.valueOf(integers[0]);
String monthStart = String.valueOf(integers[1]);
String yearStart = String.valueOf(integers[2]);
String dayEnd = String.valueOf(integers[3]);
String monthEnd = String.valueOf(integers[4]);
String yearEnd = String.valueOf(integers[5]);
String[] strings = {dayStart, monthStart, yearStart, dayEnd, monthEnd, yearEnd};
int k = 0;
for(String s: strings){
if(s.length() < 2){
strings[k] = "0" + s;
}
k++;
}
dayStart = strings[0];
monthStart = strings[1];
yearStart = strings[2];
dayEnd = strings[3];
monthEnd = strings[4];
yearEnd = strings[5];
try {
URL url = new URL("https://zmail.insa-lyon.fr/home/" + email_adress + "/Calendrier%20Cocktail?fmt=xml&start=" +
monthStart +
"/" +
dayStart +
"/" +
yearStart +
"&end=" +
monthEnd +
"/" +
dayEnd +
"/" +
yearEnd);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(email_adress, password.toCharArray());
}
});
conn.setRequestMethod("GET");
conn.setRequestProperty("--user", email_adress + ":" + password);
if (conn.getResponseCode() != 200) {
System.out.println("15erreur=" + url.toString());
System.out.println("15erreur=" + conn.getResponseMessage());
System.out.println("15erreur=" + conn.getRequestMethod());
return null;
}
System.out.println(conn.getResponseMessage());
InputStreamReader inputStreamReader = new InputStreamReader((conn.getInputStream()));
BufferedReader br = new BufferedReader(inputStreamReader);
String output;
StringBuilder xml = new StringBuilder();
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
xml.append(output);
}
inputStreamReader.close();
br.close();
conn.disconnect();
System.out.println(xml);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(xml.toString())));
rootElement = document.getDocumentElement();
} catch (IOException | ParserConfigurationException | SAXException e) {
e.printStackTrace();
}
return null;
}

Ok so I had to authenticate the user with the code below:
// Authentication part -------------------
String userpass = email_adress + ":" + password;
conn.setRequestProperty("X-Requested-With", "Curl");
String basicAuth = "Basic " + new String(android.util.Base64.encode(userpass.getBytes(), android.util.Base64.DEFAULT));
conn.setRequestProperty("Authorization", basicAuth);
// ----------------------------------------

Read any Language String from Google Translator in Android

I am creating a translator app where I am getting the input text from android supported voice Recognizer. Example : Hindi, Chinese, etc. Now I want to build the query like this -
public JSONObject getTranslatedText() {
StringBuilder sb = new StringBuilder();
String http = "https://translation.googleapis.com/language/translate/v2?key=xyz";
JSONObject response = null;
String json = "";
HttpURLConnection urlConnection = null;
try {
URL url = new URL(http);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/json");
urlConnection.connect();
String line1 = "{\n" + " 'q': '" + inputString + "',\n" + " 'target': '" + targetcodeString + "'\n" + "}";
DataOutputStream out = new DataOutputStream(urlConnection.getOutputStream());
out.writeBytes(line1);
out.flush();
out.close();
BufferedReader br = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "UTF-8"));
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
json = sb.toString();
response = new JSONObject(json);
} catch (MalformedURLException e) {
} catch (IOException e) {
} catch (JSONException e) {
} finally {
if (urlConnection != null) urlConnection.disconnect();
}
return response;
}
The problem is it is not encoding properly and I am getting output like this -
Example: For a word "How are you" in Hindi i.e "क्या हाल" as 9 & HG 08 * E
Can I get some help please. Thanks in advance.

Try using Html.fromHtml(yourTranslatedStr).toString().
I tried that with Hindi and it worked.

Sending POST from Android Application

I'm triyng to send POST request to the server. The following java code working for PC application, but doesn't work on my Android application. The Iternet permission is added, so, what I have to do to send this post, and what other methods and libraries I have to use to replace this code for Android?
String hostname = "xxxxxxx.box";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
Socket sock = new Socket(addr, port);
String SID = new classSID("xxxxxx").obtainSID();
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(sock.getOutputStream(),"UTF-8"));
String str = "enabled=on&username="+givenName+"&email="+givenEmail+"&password="+givenPassword+"&frominternet=on&box_admin_rights=on&phone_rights=on&homeauto_rights=on&uid=&sid="+SID+"&apply=";
////////////////////////////////////////////////////////////////////////////////////////////
wr.write("POST /system/boxuser_edit.lua HTTP/1.1");
wr.write("Host: xxxxxx:80" + "\r\n");
wr.write("Accept: text/html" + "\r\n");
wr.write("Keep-Alive: 300" + "\r\n");
wr.write("Connection: Keep-Alive" + "\r\n");
wr.write("Content-Type: application/x-www-form-urlencoded"+"\r\n");
wr.write("Content-Length: "+str.length()+"\r\n");
wr.write("\r\n");
wr.write(str+"\r\n");
wr.flush();
////////////////////////////////////////////////////////////////////////////////////////////
BufferedReader rd = new BufferedReader(new InputStreamReader(sock.getInputStream(),"UTF-8"));
String line;
while((line = rd.readLine()) != null)
Log.v("Response", line);
wr.close();
rd.close();
sock.close();
}

The issue is with creating socket on port 80. You need root permission to access port < 1024 in android. See issue

Try this: and consider using an IP instead of hostname because your android device might nto be able to resolve a local hostname
private static final String UTF_8 = "UTF-8";
/**
* #param hostNameOrIP
* : the host name or IP<br/>
* #param webService
* : the web service name<br/>
* #param classOrEndPoint
* : the file or end point<br/>
* #param method
* : the method being called<br/>
* #param parameters
* : the parameters to be sent in the message body
* #return
