MultipartEntity Files not uploading through device

Possibly this is a duplicate question but I have already tried all answer of this site but none of this working!
I am using MultipartEntity for image upload. It's working completely fine in Emulator but When I check in device its not working.
Below my code
HttpParams params = new BasicHttpParams();
params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP);
HttpClient httpClient = new DefaultHttpClient(params);
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost("http://url.com/webservice_uploadvideo.php");
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.STRICT);
FileBody filebodyVideopre = new FileBody(new File(videoUploadpathPre)); //pre
entity.addPart("fin_detail", filebodyVideopre);
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost, localContext);

Here's my working code for multi-part image uploading. Yes it works in real device.
private int uploadImage(String selectedImagePath) {
try {
HttpClient client = new DefaultHttpClient();
File file = new File(selectedImagePath);
HttpPost post = new HttpPost(Constants.URL);
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE,
Constants.BOUNDARY, Charset.defaultCharset());
entity.addPart(Constants.MULTIPART_FORM_DATA_NAME, new FileBody(file));
post.setHeader("Accept", "application/json");
post.setHeader("Content-Type", "multipart/form-data; boundary=" + Constants.BOUNDARY);
post.setEntity(entity);
HttpResponse response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
int status = response.getStatusLine().getStatusCode();
return status;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}

How do I use the apache httpClient API to send file + api key and other parameters as a single request?

I have started to test http client apache API. I need it because I would like to send requests and to receive responses to virustotal API. Virus total API requires to parameters in the post request:
the api key value (a unique value for each user)
the file itself as I understood from their website.
For example:
>>> url = "https://www.virustotal.com/vtapi/v2/url/scan"
>>> parameters = {"url": "http://www.virustotal.com",
... "apikey": "-- YOUR API KEY --"}
>>> data = urllib.urlencode(parameters)
>>> req = urllib2.Request(url, data)
At the moment, I am trying to do the same thing in Java instead of Python. Here is a part of my source code commented to guide throughout the steps:
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
//create post request
HttpPost request = new HttpPost("https://www.virustotal.com/vtapi/v2/file/scan");
//http json header
request.addHeader("content-type", "application/json");
String str = gson.toJson(param);
String fileName = UUID.randomUUID().toString() + ".txt";
try {
//API key
StringEntity entity = new StringEntity(str);
Writer writer = new BufferedWriter(new FileWriter(fileName));
writer.write(VirusDefinitionTest.malware());
request.setEntity(entity);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
FileBody fileBody = new FileBody(new File(fileName));
builder.addTextBody("my_file", fileName);
HttpEntity entity = builder.build();
request.setEntity(entity);
HttpResponse response;
try {
response = httpClient.execute(request);
...
Unfortunately, I receive HTTP/1.1 403 Forbidden. Obviously, the error is somewhere in the entities but I cannot find how to do it. Any help would be deeply welcomed.

This worked for me with Apache 4.5.2 HttpClient:
CloseableHttpClient httpclient = HttpClients.createDefault();
try {
HttpPost httppost = new HttpPost("https://www.virustotal.com/vtapi/v2/file/scan");
FileBody bin = new FileBody(new File("... the file here ..."));
// the API key here
StringBody comment = new StringBody("5ec8de.....", ContentType.TEXT_PLAIN);
HttpEntity reqEntity = MultipartEntityBuilder.create()
.addPart("apikey", comment)
.addPart("file", bin)
.build();
httppost.setEntity(reqEntity);
System.out.println("executing request " + httppost.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httppost);
try {
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
System.out.println("ToString:" + EntityUtils.toString(resEntity));
}
EntityUtils.consume(resEntity);
} finally {
response.close();
}
} finally {
httpclient.close();
}
The important part was the reqEntity which had to have two specifically named fields, "apikey", and "file". Running this with a valid API key gives me the expected response from the API.

The problem seems to be that first you add explicit "content-type" header which is "application/json" and at the end you send the Muiltipart entity. You need to add all the parameters and the file to the Muiltipart entity. Now the parameters are not send, because they are overwritten by Muiltipart entity:
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
//create post request
HttpPost request = new HttpPost("https://www.virustotal.com/vtapi/v2/file/scan");
//http json header
request.addHeader("content-type", "application/json");
String str = gson.toJson(param);
String fileName = UUID.randomUUID().toString() + ".txt";
try {
//API key
StringEntity entity = new StringEntity(str);
Writer writer = new BufferedWriter(new FileWriter(fileName));
writer.write(VirusDefinitionTest.malware());
// --> You set parameters here !!!
request.setEntity(entity);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
FileBody fileBody = new FileBody(new File(fileName));
builder.addTextBody("my_file", fileName);
HttpEntity entity = builder.build();
// --> You overwrite the parameters here !!!
request.setEntity(entity);
HttpResponse response;
try {
response = httpClient.execute(request);

Is my HTTPClient connection leaking sockets?

I have an app deployed on google app engine that uses the Apache HTTPClient. Recently as the app is getting more traffic, I have started running into exceptions where the sockets quota has been exceeded. The exception is
com.google.apphosting.api.ApiProxy$OverQuotaException: The API call remote_socket.SetSocketOptions() required more quota than is available.
I reached out to the App Engine team and they wanted me to check if my app was leaking sockets.
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("http://www.spark.com");
List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("param1", "val1"));
nvps.add(new BasicNameValuePair("param2", "val2"));
httpPost.setEntity(new UrlEncodedFormEntity(nvps));
CloseableHttpResponse response = httpclient.execute(httpPost);
Document doc = null;
try {
HttpEntity entity = response.getEntity();
doc = Jsoup.parse(entity.getContent(), "UTF-8", "");
EntityUtils.consume(entity);
} finally {
response.close();
httpclient.close();
}
This is what my http connection code looks like. Am I doing something wrong which may be causing the sockets to leak? Can I do something better?

this work for me :
HttpParams httpParameters = new BasicHttpParams();
HttpProtocolParams.setContentCharset(httpParameters, HTTP.UTF_8);
HttpProtocolParams.setHttpElementCharset(httpParameters, HTTP.UTF_8);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
// HttpPost httppost = new HttpPost("http://rafsanjan.uni-azad.my.com/json/darkhasr.php?shdaneshjo="+value_id+"&moavenat="+value_seaction+"&darkhast="+zir_item+"&startdate=test&tozih="+ value_descration); //???
try {
URIBuilder builder = new URIBuilder();
builder.setScheme("http")
.setHost("app.my.ac.com")
.setPort(1180)
.setPath("/json2/darkhasr.php")
.addParameter("shdaneshjo", value_id)
.addParameter("moavenat", value_seaction)
.addParameter("darkhast", value_item)
.addParameter("startdatet", "0")
.addParameter("tozih", value_descration)
.build();
// .fragment("section-name");
String myUrl = builder.toString();
Log.d("url=>",myUrl);
HttpPost httppost = new HttpPost(myUrl);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(8);
//nameValuePairs.add(new BasicNameValuePair("name", name));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,"UTF-8"));
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
Log.d("RESPONSE",EntityUtils.toString(resEntity));
}
catch(Exception e)
{
Log.e("log_tag", "Error: "+e.toString());
}

Get response from the web service for HttpResponse

In my application, the User can upload images to a PHP server, the iOS version is working 100%, the Android version used for this tutorial to upload image:
tutorial example
And the function I'm using is this:
public static String sendPost(String url, String imagePath)
throws IOException, ClientProtocolException {
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,
HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost(url);
File file = new File(imagePath);
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/jpeg");
mpEntity.addPart("userfile", cbFile);
httppost.setEntity(mpEntity);
//Log.e("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
//Log.e(""+response.getStatusLine());
if (resEntity != null) {
//Log.e(EntityUtils.toString(resEntity));
}
if (resEntity != null) {
resEntity.consumeContent();
}
httpclient.getConnectionManager().shutdown();
return response.toString();
}
return response.toString(); get it in org.apache.http.message.BasicHttpResponse # 406dc148
But the return of the web service is the URL where the image was saved, I need to have a string in the return of the PHP server, rather than the return I mentioned above how can I have it?
I wanted something like this (HttpURLConnection):
HttpURLConnection conn;
...
String response= "";
Scanner inStream = new Scanner(conn.getInputStream());
while(inStream.hasNextLine())
response+=(inStream.nextLine());
Log.e("resp", response);
After one hour onsegui trying to get the response from the Web service as follows:
...
byte [] responseBody = httppost.getMethod().getBytes();
Log.e("RESPONSE BODY",""+(new String(responseBody)));
...

If you want the content returned by the HTTP server, you shouldn't do this:
if (resEntity != null) {
resEntity.consumeContent();
}
... because that says "throw away the content".

Try this if the response is of type String
ResponseHandler<String> responseHandler = new BasicResponseHandler();
HttpResponse httpResponse = httpClient.execute(post, new BasicHttpContext()); // new BasicHttpContext() not necessary
// verify connection response status using httpResponse.getStatusLine().getStatusCode() then
String response = responseHandler.handleResponse(httpResponse);
if(response != mull){
Log.e("Response : "+response);
}else{
// Handle exception
}
return response;

Java httpclient to log into website and download file - Session Problems!

I log on to a website using the POST method (httpclient from apache).
I let the HttpClient execute the HttpPost, let the connection manager release it and then I want to post a GET message that opens a php-URL file to download a pdf.
But all I get is the html file of a "session expired" page
(println: File: index_GT_neu.html?fehlermeldung=fehler_sessioncheck)
I was thinking that once i used the instance of HttpClient to log on at the site, I would be able to open another URL that is only available after log on. But appearently I was wrong.
Somebody could give me a hint?
Thanks in advance!
This is what my main looks like:
// prepare post method
HttpPost post = new HttpPost("http://epaper02.niedersachsen.com/epaper/index_GT_neu.html");
//prepare get method
HttpGet httpget = new HttpGet("http://epaper01.niedersachsen.com/epaper/getfile.php?pdf=0114_GTB_HP_01.pdf&zeitung=GT&ekZeitung=&Y=11&M=01&D=14&C=0");
// add parameters to the post method
List <NameValuePair> parameters = new ArrayList <NameValuePair>();
parameters.add(new BasicNameValuePair("username", "test"));
parameters.add(new BasicNameValuePair("passwort", "test"));
UrlEncodedFormEntity sendentity = new UrlEncodedFormEntity(parameters, HTTP.UTF_8);
post.setEntity(sendentity);
// create the client and execute the post method
HttpClient client = new DefaultHttpClient();
HttpResponse postResponse = client.execute(post);
//Output the Response from the POST
System.out.print(convertInputStreamToString(postResponse.getEntity().getContent()));
//releasing POST
EntityUtils.consume(postResponse.getEntity());
//Execute get
HttpContext context = new BasicHttpContext();
HttpResponse getResponse = client.execute(httpget, context);
System.out.println("Statusline: " + getResponse.getStatusLine());
if (getResponse.getStatusLine().getStatusCode() != HttpStatus.SC_OK)
throw new IOException(getResponse.getStatusLine().toString());
HttpUriRequest currentReq = (HttpUriRequest) context.getAttribute(ExecutionContext.HTTP_REQUEST);
String currentUrl = URLDecoder.decode(currentReq.getURI().toString(), "UTF-8");
int i = currentUrl.lastIndexOf('/');
String fileName = null;
if (i < 0) {
fileName = currentUrl;
} else {
fileName = currentUrl.substring(i + 1);
}
System.out.println("File: " + fileName);
//Create file
OutputStream os = new FileOutputStream( fileName);
InputStream is = getResponse.getEntity().getContent();
byte[] buf = new byte[4096];
int read;
while ((read = is.read(buf)) != -1) {
os.write(buf, 0, read);
}
os.close();
client.getConnectionManager().shutdown();

By default, DefaultHttpClient does not have a cookie store. A cookie store is needed in order to store cookies that are populated initially or that are obtained while interacting with the HTTP client. As soon as digging into this topic you will start to think about the scope/sharing of cookies.
You can enable the cookie store with one additional line of code:
DefaultHttpClient client = new DefaultHttpClient();
client.setCookieStore(new BasicCookieStore());
I know, this might be a bit late, still HTH.

I am not familiar with this library but try creating context before calling the post and reuse the same context for the get:
HttpContext context = new BasicHttpContext();
// create the client and execute the post method
HttpClient client = new DefaultHttpClient();
HttpResponse postResponse = client.execute(post,context);
...
HttpResponse getResponse = client.execute(httpget, context);
