How to insert utf8 character data from android to codeigniter server

I am trying to insert UTF-8 characters(Like username in hindi or tamil language) in MySql with Codeigniter framework.
Here is my android side code:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(uploadApi);
try {
List<NameValuePair> nameValuePairs=new ArrayList<>();
nameValuePairs.add(new BasicNameValuePair("key1","विकिपीडिया"));
nameValuePairs.add(new BasicNameValuePair("key2","इण्टरनेट"));
UrlEncodedFormEntity form = new UrlEncodedFormEntity(nameValuePairs);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
and this is server side code in codeigniter:
public function create()
{
$name=$this->input->get_post("name") ;$text=$this->input->get_post("text");
$type=$this->input->get_post("type");$contact=$this->input->get_post("contact");
$mp=$this->input->get_post("mp");$mla=$this->input->get_post("mla");
$position=$this->input->get_post("position");
$config['upload_path'] = './uploads/';
$config['allowed_types'] = '*';
$config['max_size'] = '20000';
$config['max_width'] = '2000';
$config['max_height'] = '2000';
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ( ! $this->upload->do_upload('image'))
{
$image="noimage.jpg";
echo $this->upload->display_errors();
}
else
{
$data = $this->upload->data();
$image=$data['file_name'];
}
$data['json']=$this->uploadmodel->insert($name,$image,$text,$contact,$mp,$mla,$type,$position);
echo "Thanks for Sharing";
}
All configuration is set to utf-8 in configuration file.
error is i am getting all string like ?????????
please tell me where i am doing wrong.
Thanks

I added this line:
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
Although i tried with it also before.
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,"utf-8"));
but the above runs successfully.

Cant send json to server

I'm trying to send a json file to remote server. If I try it, using this site:
https://www.hurl.it/ passing a json like this:
it works. But If I try it from my code, I have some trouble.
ArrayList<NameValuePair> nameValuePairs1 = new ArrayList<NameValuePair>();
JSONArray list1 = new JSONArray();
list1.add("12345678");
Map obj=new LinkedHashMap();
obj.put("company_id","1");
obj.put("phones", list1);
obj.put("name","Alexy");
obj.put("birthdate","12.03.2014");
obj.put("email","nesalexy#mail.ru");
nameValuePairs1.add(new BasicNameValuePair("json", obj.toString()));
try {
URL url = new URL("http://crm.pavlun.info/api/register");
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url.toURI());
httpPost.setEntity(new StringEntity(nameValuePairs1.toString(), "UTF-8"));
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "application/json");
HttpResponse response = httpClient.execute(httpPost);
Log.e("r ", response.toString());
}catch(Exception e) {
e.printStackTrace();
}
This is my json example: I need to create something like this: "json":{"company_id":"1","phones":["555555"],"photo":"/files/clients_photos/tmp/484629825.JPG","name":"sdfsdfdsf","birthdate":"10.02.2014", "email":"sdf#sdf.ff"}
UPD:
I have the following error:
{"status":"error","message":"Customer data is empty!"}
Maybe something is wrong in my json.
UDP:
working code
ArrayList<NameValuePair> nameValuePairs1 = new ArrayList<NameValuePair>();
JSONObject joB = new JSONObject();
JSONArray list1 = new JSONArray();
list1.add("258963147");
Map obj=new LinkedHashMap();
obj.put("company_id","1");
obj.put("phones", list1);
obj.put("name","Alexy");
obj.put("birthdate","12.03.2014");
obj.put("email","nesalexy#mail.ru");
org.json.JSONObject jsonqwe;
try {
JSONParser operationLink = new JSONParser();
ArrayList<NameValuePair> postP = new ArrayList<NameValuePair>();
postP.add(new BasicNameValuePair("json", JSONValue.toJSONString(obj)));
jsonqwe = operationLink.makeHttpRequest("http://crm.pavlun.info/api/register", "POST", postP);
Log.e("sad", jsonqwe.toString());
}catch(Exception e) {
e.printStackTrace();
}

You're problem is that you're not building a JSON object, but using the map's toString() method, which won't give you a properly formatted JSON object.
Try JSONObject's constructor that takes a map as parameter. And than call toString() on the JSONObject.

Try yo change
Map obj=new LinkedHashMap();
to
JSONObject obj=new JSONObject();
you need to send a JSON value

A more suitable solution would be to build a JSONObject instead of the Map you're using. Something like this:
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
JSONArray phoneNumbers = new JSONArray();
phoneNumbers.add("12345678");
JSONObject obj=new JSONObject();
obj.put("company_id","1");
obj.put("phones", phoneNumbers);
obj.put("name","Alexy");
obj.put("birthdate","12.03.2014");
obj.put("email","nesalexy#mail.ru");
nameValuePairs.add(new BasicNameValuePair("json", obj.toString()));
try {
URL url = new URL("http://crm.pavlun.info/api/register");
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url.toURI());
httpPost.setEntity(new StringEntity(nameValuePairs.toString(), "UTF-8"));
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "application/json");
HttpResponse response = httpClient.execute(httpPost);
Log.e("r ", response.toString());
}catch(Exception e) {
e.printStackTrace();
}

This line will return garbage (as far server is concerned)
nameValuePairs1.toString()
because an ArrayList does implement toString like you are expecting. You should be using JSONArray/JSONObject instead.

In the hurl site example one name valu pair is sent. To send name value pais your content type should be form url encoded. So change:
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "application/json");
to
httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
Maybe this will help:
httpPost.setHeader("ENCTYPE","multipart/form-data");
EDIT:
As others already stated do not use a Map but a JSONObject. Then change
httpPost.setEntity(new StringEntity(nameValuePairs1.toString()));
to:
String nameValuPairsText = nameValuePairs.toString();
nameValuPairsText = nameValuPairsText.substring(1, nameValuPairsText.length()-1);
httpPost.setEntity(new StringEntity(nameValuPairsText, "UTF-8"));

I got my answer by my way.Hello all for your responses but i got myy question solved by my way ,Actually all are telling me about different parsing but i want to know about the parsing from HTTP RESPONSE,So i have got my solution,here it is:
http://www.java2s.com/Code/Android/Development/getCharacterDataFromElement.htm
Thanks for this useful post.

String xml="<yourxml></yourxml>"
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Content-Type", "application/xml");
StringEntity entity = new StringEntity(xml);
httpPost.setEntity(entity);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
xml = EntityUtils.toString(httpEntity);

Android Getting JSON return error from POST Http execution

I'm currently trying to send data via POST to a server, and the server is handling the data and appends it to a JSON file. I'm currently getting a 422 error and I've been receiving it for a while now. My question is: How do I receive that JSON error itself in Java so that I can see what the error is. All I'm seeing is a HttpResponseException and it doesn't give me anything else. Thanks for the time and help in advance.
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(mPath);
// Add your data
try
{
List nameValuePairs = new ArrayList(4);
httppost.setHeader("Authorization", Base64.encodeToString(new StringBuilder(bundleId).append(":").append(apiKey).toString().getBytes("UTF-8"), Base64.URL_SAFE|Base64.NO_WRAP));
nameValuePairs.add(new BasicNameValuePair("state", "CA"));
nameValuePairs.add(new BasicNameValuePair("city", "AndDev is Cool!"));
nameValuePairs.add(new BasicNameValuePair("body", "dsads is assrawstjljalsdfljasldflkasjdfjasldjflasjdflkjaslfggddsfgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfddjflaskjdfkasjdlfkjasldfkjalskdjfajasldfkasdlfjasljdflajsdfjasdjflaskjdflaksjdfljasldfkjasljdflajsasdlfkjasldfkjlas!"));
nameValuePairs.add(new BasicNameValuePair("title", "dsaghhhe fd!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
//HttpResponse response = httpclient.execute(httppost);
//int status = response.getStatusLine().getStatusCode();
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpclient.execute(httppost, responseHandler);
Log.v(TAG, "response: " + responseBody);
//JSONObject response = new JSONObject(responseBody);
int f = 0;
}
catch(HttpResponseException e)
{
Log.e(TAG, e.getLocalizedMessage());
Log.e(TAG, e.getMessage());
e.printStackTrace();
}

you may send your parameters more conveniently by using predefined Json class as below:
String jsonParam = null;
try{
JSONObject param = new JSONObject();
param.put("state", "CA");
param.put("city", "AndDev is Cool!");
//and so on with other parameters
jsonParam = param.toString();
}
catch (Exception e) {
// TODO: handle exception
}
and set the post entity as:
if(jsonParam != null)
httppost.setEntity(new StringEntity(jsonParam, HTTP.UTF_8));

422 error says: Unprocessable Entity - The request was well-formed but was unable to be followed due to semantic errors
You got a problem with UrlEncodedFormEntity

Android: Http post with parameters not working

I need to create an HTTP POST request with parameters. I know there are many examples out there, I have tried using HTTPparams, NameValuePair etc but cant seem to get the correct format for the server.
Server Type: REST based API utilizing JSON for data transfer
Content-type: application/json
Accept: application/json
Content-length: 47
{"username":"abcd","password":"1234"}
I can pass these headers but I cant seem to pass these params "username","password". Here is my code:
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.mymi5.net/API/auth/login");
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("username","abcd"));
pairs.add(new BasicNameValuePair("password","1234"));
post.setHeader("Content-type", "application/json");
post.setHeader("Accept", "application/json");
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs,"UTF-8");
post.setEntity(entity);
HttpResponse response = client.execute(post);
I tried to debug, but cant see if entity is attached properly or not... What am I doing wrong?
Thanks in Advance.
Maaz

Try this:
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.mymi5.net/API/auth/login");
post.setHeader("Content-type", "application/json");
post.setHeader("Accept", "application/json");
JSONObject obj = new JSONObject();
obj.put("username", "abcd");
obj.put("password", "1234");
post.setEntity(new StringEntity(obj.toString(), "UTF-8"));
HttpResponse response = client.execute(post);

I'm not quite sure, from your description, but it would seem that your server expects a JSON content object instead of the data being encoded in the URL. Send something like this as the body of your post:
{"username":"abcd","password":"1234"}

HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.mymi5.net/API/auth/login");
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("username","abcd"));
pairs.add(new BasicNameValuePair("password","1234"));
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(pairs,HTTP.UTF_8);
post.setEntity(entity);
HttpResponse response = client.execute(post);
just try this coz it works perfect for me when i am trying to HTTP post.

this will probably work for you.
assuming you already have the json object.
NOTE: (1)in the server you need to handle th request as utf-8 (also in the DB).
#SuppressWarnings("unchecked")
private static HttpResponse executePostRequest(JSONObject jsonData, String url) {
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httpost = new HttpPost(url);
try {
httpost.setEntity(new ByteArrayEntity(jsonData.toString().getBytes("UTF8")));
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json;charset=UTF-8");
httpost.setHeader("Accept-Charset", "utf-8");
HttpResponse httpResponse = httpclient.execute(httpost);
return httpResponse;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
then in the client handle the server response like this:
String responseBody = EntityUtils
.toString(response.getEntity(), "UTF-8");
