sending multiple images to rest api using multipart

Question

I did this for uploading single image . But i want upload multiple image like 5 images in same key. Anyone tell me how to do it using multipart

HttpPost post = new HttpPost(SIGNUP_URL);
            MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            ContentBody body=new FileBody(new File(obj.getBannerPath()),"image/*");
            multipartEntity.addPart(KEY_BANNER, body);
            multipartEntity.addPart(KEY_BUSINESS_NAME,new StringBody(obj.getBusinessName()));
            multipartEntity.addPart(KEY_DESCRIPTION,new StringBody(obj.getDescription()));
            multipartEntity.addPart(KEY_ADDRESS,new StringBody(obj.getAddress()));

post.setEntity(multipartEntity);

            response=client.execute(post);

Try this Code,

HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 60000); // 1 min
HttpConnectionParams.setSoTimeout(httpParams,60000); // 1 min

HttpClient client = new DefaultHttpClient(httpParams);
//
// HttpPost post = new
//HttpPost("ex.php/my_api/my_service_api_test/event_user_data");
HttpPost post = new HttpPost(AppConstants.URL_BASE + "event_user_data");
MultipartEntity entity = new MyMultipartEntity(new ProgressListener() {

                @Override
                public void transferred(long num) {
                    // TODO Auto-generated method stub

                    publishProgress((int) ((num / (float) totalSize) *100));
                }
            });

                    text.put("post_type", posttype);
                    File myFile2 = new File(postpath);
                    fileBody = new FileBody(myFile2, "image/jpeg");

Try Folllowing code

protected WebserviceResultData doInBackground(Void... params) {
    Object resultObject = null;
    WebserviceResultData webserviceResultData = null;

    // ******************************************************************
    try {

        // Create the POST object
        HttpPost post = new HttpPost(webServiceData.serverUrl);

        // ********************************************************************************************************************

        // Create the multipart entity object and add a progress listener
        // this is a our extended class so we can know the bytes that have
        // been transfered
        MultipartEntity entity = new MyMultipartEntity(new ProgressListener() {
            @Override
            public void transferred(long num) {
                publishProgress((int) ((num / (float) totalSize) * 100));
                Log.d("DEBUG", num + " - " + totalSize);

            }
        });
        // Add the file to the content's body
        ContentBody cbFile = null;
        for (int i = 0; i < strImagePath.size(); i++) {
            File file = new File(strImagePath.get(i));
            cbFile = new FileBody(file, "image/jpeg");

            entity.addPart("source", cbFile);
        }
        // entity.addPart("source", cbFile);

        // After adding everything we get the content's lenght
        totalSize = entity.getContentLength();

        // We add the entity to the post request
        post.setEntity(entity);

        // Execute post request
        HttpResponse response = client.execute(post);
        // int statusCode = response.getStatusLine().getStatusCode();

        String resObj = EntityUtils.toString(response.getEntity());

        if (resObj != null) {
            Logger.logger("===============================================");
            Logger.logger("Responce---------", "" + resObj.toString());
            Logger.logger("===============================================");
            resultObject = getParsedResponse(resObj, webServiceData.parsedClass);
            webserviceResultData = new WebserviceResultData(resultObject, webServiceData);
        }

        return webserviceResultData;

    } catch (ClientProtocolException e) {
        // Any error related to the Http Protocol (e.g. malformed url)
        e.printStackTrace();
    } catch (IOException e) {
        // Any IO error (e.g. File not found)
        e.printStackTrace();
    }

    return null;
    // ******************************************************************
