Android Http Response is incomplete. Returns an unterminated json object

I am using HttpClient 4.3.6 to perform http GET and POST requests. Right now I am using multipartentity to send a few string parameters and an image in the form of a file. I am able to successfully post the data but my problem comes in when I get the HTTP response. The response contains json data.
What happens is the HTTP response is incomplete and when i try to create a json object with the data i get jsonexception error saying:
Unterminated object at character 407.
I noticed that the response does not contain closed braces. Is this a problem on android or should I check the server? Because I am able to see the data properly on postman and on ios. I have never faced this issue before and don't know how to solve this.
This is my code to post and get the response:
#Override
protected String doInBackground(String... params) {
try {
String url = params[0];
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
MultipartEntity entity = new MultipartEntity();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
ByteArrayBody bab = new ByteArrayBody(imageBytes, "image.jpg");
entity.addPart("image_data", bab);
entity.addPart("action", new StringBody("1", "text/plain", Charset.forName("UTF-8")));
entity.addPart("name", new StringBody("asdfg", "text/plain", Charset.forName("UTF-8")));
entity.addPart("user_id", new StringBody("157", "text/plain", Charset.forName("UTF-8")));
entity.addPart("birthday", new StringBody("18-04-1995", "text/plain", Charset.forName("UTF-8")));
entity.addPart("gender", new StringBody("male", "text/plain", Charset.forName("UTF-8")));
entity.addPart("is_jlpt_student", new StringBody(String.valueOf(0), "text/plain", Charset.forName("UTF-8")));
entity.addPart("relationship", new StringBody("Father", "text/plain", Charset.forName("UTF-8")));
entity.addPart("relationship_id", new StringBody(String.valueOf(10002), "text/plain", Charset.forName("UTF-8")));
entity.addPart("is_creator", new StringBody(String.valueOf(1), "text/plain", Charset.forName("UTF-8")));
entity.addPart("email", new StringBody(email, "text/plain", Charset.forName("UTF-8")));
httppost.setEntity(entity);
HttpResponse resp = httpclient.execute(httppost);
String response = EntityUtils.toString(resp.getEntity());
Log.i("HttpResponse", response);
return response;
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute (String result) {
super.onPostExecute(result);
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(result);
JSONObject json_data = jsonObject.getJSONObject("data");
String json_userid = json_data.getString("user_id");
String json_username = json_data.getString("name");
String json_email = json_data.getString("email");
String json_country = json_data.getString("country_code");
String json_imagefilename = json_data.getString("image_filename");
String json_imgurl = json_data.getString("image_url");
Toast.makeText(ParentGuardianProfile.this, "ImageFile " + json_imagefilename, Toast.LENGTH_SHORT).show();
User new_user = userdao.createUser(json_userid, json_username, json_email,json_imagefilename,json_country,selectedImageUri.toString(), 1);
Log.i("SQLITE", "added user : " + new_user.getmUserName() + new_user.getmId());
} catch (JSONException e) {
e.printStackTrace();
}
}
And my json response is :
{"status":1,"message":"success","data":{"child_id":"381","name":"asdfg","image_filename":"C201603021734476.jpg","image_url":"https:\/\/innokid.blob.core.windows.net\/media\/child\/381.jpg","birthday":"18-04-1995","gender":"male","is_jltp_student":"0","relationship":"Father","relationship_id":"10002","is_creator":1,"rank":1,"qrcode_url":"http:\/\/innokid.azurewebsites.net\/uploads\/qrcode\/child_381.png"
I tried using String buffer as suggested in this post String is being truncated when its too long . But i still get the same result.

Code looks ok at first glance.
How do you got know that the json data is cut? Logcat can truncate text. Debugger should be more reliable in this case.
Try to generate this same request with some tools like curl / SoapUI and validate JSON you got with some formatter / validator (you'll easily find a few of such tools).
It's beyond the range of question, but using raw Android built-in communication libraries seems to be a little bit masochistic. Have you ever consider to use Retrofit?

I think this code is problematic String response = EntityUtils.toString(resp.getEntity());
may be you should use some other function to convert response toString...
Apparently the json is missing two curly brackets '}}' at the end, which can happen due to some bug in the toString code.

I pulled up an old project that was using the org.apache.http stuff and below is how I was parsing the response. As you can see it is rather cumbersome. There are many tested and maintained libraries out there that are better suited to this kind of heavy-lifting.
// Get hold of the response entity (-> the data):
HttpEntity entity = response.getEntity();
if (entity != null) {
// Read the content stream
InputStream instream = entity.getContent();
Header contentEncoding = response.getFirstHeader("Content-Encoding");
if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) {
instream = new GZIPInputStream(instream);
}
// Convert content stream to a String
resultString = convertStreamToString(instream);
instream.close();
// Do stuff with resultString here
// Consume Content
entity.consumeContent();
}
And the convertStreamToString() method:
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the
* BufferedReader.readLine() method. We iterate until the BufferedReader
* return null which means there's no more data to read. Each line will
* appended to a StringBuilder and returned as String.
*
* (c) public domain:
* http://senior.ceng.metu.edu.tr/2009/praeda/2009/01/
* 11/a-simple-restful-client-at-android/
*/
BufferedReader reader = new BufferedReader(new InputStreamReader(is), 8192);
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}

I finally solved this issue by replacing httpclient library with Android Asynchronous Http Client. Now it works fine. Thanks a lot for your help!
However, I still dont understand why the response was truncated when i used httpclient.

How to handle 500 Internal Server Error when using JSON

I am relatively new to Android and I am using JSON to get data from a server. On the first loop at line 22, the StringBuilder contains, 500 Internal Server Error and then the jArray ends up coming back null. How can I handle this error?
public static JSONObject getJSON() {
String jsonString = "";
InputStream inStream = null;
//http post
JSONObject jArray = null;
try {
HttpClient httpClient = new DefaultHttpClient(new BasicHttpParams());
HttpPost httpPost = new HttpPost(WS_URL);
httpPost.setHeader("Content-type", "application/json");
HttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
inStream = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
inStream.close();
jsonString = sb.toString();
jArray = new JSONObject(jsonString);
//outputTransactions(jArray);
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return jArray;
}

Though its a late reply but it might help others. You need to check the response status from the server before parsing it as JSON.
For ex.
int status_code=response.getStatusLine().getStatusCode();
if(status_code!=200){
Log.d("MYLOG","ERROR! Response status is"+status_code);
}
else{
inStream = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
inStream.close();
// Rest of your code......
}
or Optionally you can check the status code and display the error to the user
Like:
else if(status_code==404){
Log.d("MYLOG","Sorry! Page not found! Check the URL ");
}else if(status_code==500){
Log.d("MYLOG","Server is not responding! Sorry try again later..");
}
Hope it helps for newbies like you :-)

A "500 Internal Server" error means the server had a problem responding to your request. You are not getting a JSON string response.
Then when you try to create your jArray, the string is not valid JSON and the JSONObject cannot parse it - it returns "null" as you say.
You can parse the server response to see if it contains this string, and then create whatever jArray object you want, but you can't get a JSON object from a non-JSON string.

Take a look at this answer: https://stackoverflow.com/a/8148785/1974614
You should check the statusCode against 500

You should consider use a library to handle the REST requests like: http://square.github.io/retrofit/
If you use a library like that you can get an object from json when a success response is available and other when an error occur.
MyApi mylogin = restAdapter.create(MyApi.class); //this is how retrofit create your api
mylogin.login(username,password,new Callback<String>() {
#Override
public void success(String s, Response response) {
//process your response if login successfull you can call Intent and launch your main activity
}
#Override
public void failure(RetrofitError retrofitError) {
retrofitError.printStackTrace(); //to see if you have errors
}
});
}

I got the same problem like you and I solved it because I missed a part while adding GSON .jar files to adding my serverside project. I think you should carrefully add external libraries to your project too like me.With these links I could aware of problem .

Downloading a JSON Array from a URL in Android

I'm trying to download a JSON file in this format
[
{
"CRN":"10001",
"Course":"REG1"
},
{
"CRN":"10002",
"Course":"REG2"
}
]
I understand how to use a JSONArray class once it is created but I don't know how to create the JSONArray object from the file. If the URL location of the file were to be "www.test.com" how would I go about downloading it in background upon the launch of my application so as to not interfere with the launching of the app but not require the user to manually download it themselves.

You might want to check out this helpful library: Retrofit
It makes grabbing and parsing JSON data easy!

I think you should look for Android Web Service example. Where you can find info about
1.How to make a HTTP request to server (using URL eg. www.google.com)
2. How to handle Response from Server
3. How to parse JSON/XML response from Server etc.
Here is the Simple Tutorial I Found for you.
Android Web service for Log-in and Registration
Just go through step by step.
In the example we are making request to server for login and getting response then going ahead in app.
Here is the code snipp.
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}

A good way to download the JSON file automatically, would be to launch an AsyncTask during your onCreate method of the home activity.
JSON files are nothing more than text files in a special format, so the could be easily downloaded as a response from a HttpURLConnection, and then be treated as a String.
A suggestion for parsing the JSON objets into Java objects would be the Jackson JSON Processor. You could use the class ObjectMapper of this library to automatically create the objects.
If you are planing to implement the server side by yourself, and you also need a library to send JSON objects, you could use Jersey on both server and client.

Android parse json from url and store it

Hi there i'm creating my first android app and i'm wanting to know what is the best and most efficient way of parsing a JSON Feed from a URL.Also Ideally i want to store it somewhere so i can keep going back to it in different parts of the app. I have looked everywhere and found lots of different ways of doing it and i'm not sure which to go for. In your opinion whats the best way of parsing json efficiently and easily?

I'd side with whatsthebeef on this one, grab the data and then serialize to disk.
The code below shows the first stage, grabbing and parsing your JSON into a JSON Object and saving to disk
// Create a new HTTP Client
DefaultHttpClient defaultClient = new DefaultHttpClient();
// Setup the get request
HttpGet httpGetRequest = new HttpGet("http://example.json");
// Execute the request in the client
HttpResponse httpResponse = defaultClient.execute(httpGetRequest);
// Grab the response
BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
// Instantiate a JSON object from the request response
JSONObject jsonObject = new JSONObject(json);
// Save the JSONOvject
ObjectOutput out = new ObjectOutputStream(new FileOutputStream(new File(getCacheDir(),"")+"cacheFile.srl"));
out.writeObject( jsonObject );
out.close();
Once you have the JSONObject serialized and save to disk, you can load it back in any time using:
// Load in an object
ObjectInputStream in = new ObjectInputStream(new FileInputStream(new File(new File(getCacheDir(),"")+"cacheFile.srl")));
JSONObject jsonObject = (JSONObject) in.readObject();
in.close();

Your best bet is probably GSON
It's simple, very fast, easy to serialize and deserialize between json objects and POJO, customizable, although generally it's not necessary and it is set to appear in the ADK soon. In the meantime you can just import it into your app. There are other libraries out there but this is almost certainly the best place to start for someone new to android and json processing and for that matter just about everyone else.
If you want to persist you data so you don't have to download it every time you need it, you can deserialize your json into a java object (using GSON) and use ORMLite to simply push your objects into a sqlite database. Alternatively you can save your json objects to a file (perhaps in the cache directory)and then use GSON as the ORM.

This is pretty straightforward example using a listview to display the data. I use very similar code to display data but I have a custom adapter. If you are just using text and data it would work fine. If you want something more robust you can use lazy loader/image manager for images.

Since an http request is time consuming, using an async task will be the best idea. Otherwise the main thread may throw errors. The class shown below can do the download asynchronously
private class jsonLoad extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
} catch (Exception e) {
e.printStackTrace();
}
}
return response;
}
#Override
protected void onPostExecute(String result) {
// Instantiate a JSON object from the request response
try {
JSONObject jsonObject = new JSONObject(result);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
File file = new File(getApplicationContext().getFilesDir(),"nowList.cache");
try {
file.createNewFile();
FileOutputStream writer = openFileOutput(file.getName(), Context.MODE_PRIVATE);
writer.write(result);
writer.flush();
writer.close();
}
catch (IOException e) { e.printStackTrace(); return false; }
}
}
Unlike the other answer, here the downloaded json string itself is saved in file. So Serialization is not necessary
Now loading the json from url can be done by calling
jsonLoad jtask=new jsonLoad ();
jtask.doInBackground("http:www.json.com/urJsonFile.json");
this will save the contents to the file.
To open the saved json string
File file = new File(getApplicationContext().getFilesDir(),"nowList.cache");
StringBuilder text = new StringBuilder();
try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while ((line = br.readLine()) != null) {
text.append(line);
text.append('\n');
}
br.close();
}
catch (IOException e) {
//print log
}
JSONObject jsonObject = new JSONObject(text);

How to send POST request in JSON using HTTPClient in Android?

I'm trying to figure out how to POST JSON from Android by using HTTPClient. I've been trying to figure this out for a while, I have found plenty of examples online, but I cannot get any of them to work. I believe this is because of my lack of JSON/networking knowledge in general. I know there are plenty of examples out there but could someone point me to an actual tutorial? I'm looking for a step by step process with code and explanation of why you do each step, or of what that step does. It doesn't need to be a complicated, simple will suffice.
Again, I know there are a ton of examples out there, I'm just really looking for an example with an explanation of what exactly is happening and why it is doing that way.
If someone knows about a good Android book on this, then please let me know.
Thanks again for the help #terrance, here is the code I described below
public void shNameVerParams() throws Exception{
String path = //removed
HashMap params = new HashMap();
params.put(new String("Name"), "Value");
params.put(new String("Name"), "Value");
try {
HttpClient.SendHttpPost(path, params);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

In this answer I am using an example posted by Justin Grammens.
About JSON
JSON stands for JavaScript Object Notation. In JavaScript properties can be referenced both like this object1.name and like this object['name'];. The example from the article uses this bit of JSON.
The Parts
A fan object with email as a key and foo#bar.com as a value
{
fan:
{
email : 'foo#bar.com'
}
}
So the object equivalent would be fan.email; or fan['email'];. Both would have the same value
of 'foo#bar.com'.
About HttpClient Request
The following is what our author used to make a HttpClient Request. I do not claim to be an expert at all this so if anyone has a better way to word some of the terminology feel free.
public static HttpResponse makeRequest(String path, Map params) throws Exception
{
//instantiates httpclient to make request
DefaultHttpClient httpclient = new DefaultHttpClient();
//url with the post data
HttpPost httpost = new HttpPost(path);
//convert parameters into JSON object
JSONObject holder = getJsonObjectFromMap(params);
//passes the results to a string builder/entity
StringEntity se = new StringEntity(holder.toString());
//sets the post request as the resulting string
httpost.setEntity(se);
//sets a request header so the page receving the request
//will know what to do with it
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json");
//Handles what is returned from the page
ResponseHandler responseHandler = new BasicResponseHandler();
return httpclient.execute(httpost, responseHandler);
}
Map
If you are not familiar with the Map data structure please take a look at the Java Map reference. In short, a map is similar to a dictionary or a hash.
private static JSONObject getJsonObjectFromMap(Map params) throws JSONException {
//all the passed parameters from the post request
//iterator used to loop through all the parameters
//passed in the post request
Iterator iter = params.entrySet().iterator();
//Stores JSON
JSONObject holder = new JSONObject();
//using the earlier example your first entry would get email
//and the inner while would get the value which would be 'foo#bar.com'
//{ fan: { email : 'foo#bar.com' } }
//While there is another entry
while (iter.hasNext())
{
//gets an entry in the params
Map.Entry pairs = (Map.Entry)iter.next();
//creates a key for Map
String key = (String)pairs.getKey();
//Create a new map
Map m = (Map)pairs.getValue();
//object for storing Json
JSONObject data = new JSONObject();
//gets the value
Iterator iter2 = m.entrySet().iterator();
while (iter2.hasNext())
{
Map.Entry pairs2 = (Map.Entry)iter2.next();
data.put((String)pairs2.getKey(), (String)pairs2.getValue());
}
//puts email and 'foo#bar.com' together in map
holder.put(key, data);
}
return holder;
}
Please feel free to comment on any questions that arise about this post or if I have not made something clear or if I have not touched on something that your still confused about... etc whatever pops in your head really.
(I will take down if Justin Grammens does not approve. But if not then thanks Justin for being cool about it.)
Update
I just happend to get a comment about how to use the code and realized that there was a mistake in the return type.
The method signature was set to return a string but in this case it wasnt returning anything. I changed the signature
to HttpResponse and will refer you to this link on Getting Response Body of HttpResponse
the path variable is the url and I updated to fix a mistake in the code.

Here is an alternative solution to #Terrance's answer. You can easly outsource the conversion. The Gson library does wonderful work converting various data structures into JSON and the other way around.
public static void execute() {
Map<String, String> comment = new HashMap<String, String>();
comment.put("subject", "Using the GSON library");
comment.put("message", "Using libraries is convenient.");
String json = new GsonBuilder().create().toJson(comment, Map.class);
makeRequest("http://192.168.0.1:3000/post/77/comments", json);
}
public static HttpResponse makeRequest(String uri, String json) {
try {
HttpPost httpPost = new HttpPost(uri);
httpPost.setEntity(new StringEntity(json));
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
return new DefaultHttpClient().execute(httpPost);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
Similar can be done by using Jackson instead of Gson. I also recommend taking a look at Retrofit which hides a lot of this boilerplate code for you. For more experienced developers I recommend trying out RxAndroid.

I recommend using this HttpURLConnectioninstead HttpGet. As HttpGet is already deprecated in Android API level 22.
HttpURLConnection httpcon;
String url = null;
String data = null;
String result = null;
try {
//Connect
httpcon = (HttpURLConnection) ((new URL (url).openConnection()));
httpcon.setDoOutput(true);
httpcon.setRequestProperty("Content-Type", "application/json");
httpcon.setRequestProperty("Accept", "application/json");
httpcon.setRequestMethod("POST");
httpcon.connect();
//Write
OutputStream os = httpcon.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
writer.write(data);
writer.close();
os.close();
//Read
BufferedReader br = new BufferedReader(new InputStreamReader(httpcon.getInputStream(),"UTF-8"));
String line = null;
StringBuilder sb = new StringBuilder();
while ((line = br.readLine()) != null) {
sb.append(line);
}
br.close();
result = sb.toString();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

Too much code for this task, checkout this library https://github.com/kodart/Httpzoid
Is uses GSON internally and provides API that works with objects. All JSON details are hidden.
Http http = HttpFactory.create(context);
http.get("http://example.com/users")
.handler(new ResponseHandler<User[]>() {
#Override
public void success(User[] users, HttpResponse response) {
}
}).execute();

There are couple of ways to establish HHTP connection and fetch data from a RESTFULL web service. The most recent one is GSON. But before you proceed to GSON you must have some idea of the most traditional way of creating an HTTP Client and perform data communication with a remote server. I have mentioned both the methods to send POST & GET requests using HTTPClient.
/**
* This method is used to process GET requests to the server.
*
* #param url
* #return String
* #throws IOException
*/
public static String connect(String url) throws IOException {
HttpGet httpget = new HttpGet(url);
HttpResponse response;
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.
// The default value is zero, that means the timeout is not used.
int timeoutConnection = 60*1000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 60*1000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
try {
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
result = convertStreamToString(instream);
//instream.close();
}
}
catch (ClientProtocolException e) {
Utilities.showDLog("connect","ClientProtocolException:-"+e);
} catch (IOException e) {
Utilities.showDLog("connect","IOException:-"+e);
}
return result;
}
/**

*/
static public String postHTPPRequest(String URL, String paramenter) {
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is established.

int timeoutConnection = 60*1000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)

int timeoutSocket = 60*1000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
