Sending json object using HttpsUrlConnection in android

I am sending a json object to the server using HttpsUrlConnection as following

try{ 
    JSONObject jobj=new JSONObject();

    jobj.put("UserName","demo1");
    jobj.put("Password","demo1");
    Log.e("json string :",jobj.toString());

    byte[] postData = jobj.toString().getBytes();

    URL url = new URL("https://services.myovs.com/TokenService/Token");

    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

    conn.setDoOutput(true);
    conn.setDoInput(true);
    conn.setUseCaches(false);

    conn.setRequestMethod("POST");
    conn.setRequestProperty("Content-Type", "application/json");

    OutputStream out = conn.getOutputStream();

    out.write(postData);
    out.close();

    String temp = ((HttpsURLConnection)conn).getResponseMessage();
    Log.e("response  :",temp);
} catch(Exception ex) {
    ex.printStackTrace();   
}

and

TrustManager[] trustAllCerts = new TrustManager[] {
    new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }
        public void checkClientTrusted(
                java.security.cert.X509Certificate[] certs,
                String authType) {}
        public void checkServerTrusted(
                java.security.cert.X509Certificate[] certs,
                String authType) {}
    }
};

but its getting an exception like

As far as I can tell, it's not an exception. Instead it's a warning written to the log including a stacktrace.

The warning indicates that the connection is not secure because the hostname could not be verified. It has to do with the HTTPS (as opposed to a HTTP) connection you're using. The server probably doesn't have a certificate issued by a publicly known certificate authority.
