Crash on Sending HTTP post request from android

I was trying to send HTTP request from Android with using the pieces of codes I found in SO but I ve got two problems. First one is how can I put a header to my http request. Second one is when I try to execute it(httpclient.execute) I get the following error. I already tried the url with advanced rest client and got a valid response.

Here is a successfull request

POST /api/v1/login/ HTTP/1.1
HOST: api.example.com
user-agent: Example
content-type: application/json
content-length: 47

{"username":"test", "password":"123456"}

Here is my code.

String restUrl="https://api.example.com/api/v1/login/";

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(restUrl);

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("username", mJidView.getText().toString()));
            nameValuePairs.add(new BasicNameValuePair("password",mPasswordView.getText().toString() ));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();

I get error in httpclient.execute(httppost) Here is the additional logcat.

Have you tried setting a header for your Post request? like this

 httpPost.addHeader("content-type", "application/x-www-form-urlencoded;charset=UTF-8");
 httpPost.setHeader("Accept", "application/json");
 httpPost.setHeader("Accept-Charset", "utf-8");
 httpPost.setEntity(new UrlEncodedFormEntity(NameValuePairs, "UTF-8"));

Edit:

String restUrl="https://api.example.com/api/v1/login/";

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(restUrl);

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("username", mJidView.getText().toString()));
        nameValuePairs.add(new     BasicNameValuePair("password",mPasswordView.getText().toString() ));
        httpPost.addHeader("content-type", "application/x-www-form-urlencoded; charset=UTF-8");
        httpPost.setHeader("Accept", "application/json");
        httpPost.setHeader("Accept-Charset", "utf-8");

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
        }catch (UnsupportedEncodingException e) {
            e.printStackTrace();

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
