Android- POST multipart form data

Question

I would like to send multipart form with video and data such as Email and name. The following is my code and it does not work ,there is no response from the server

File file =new File(VideoPath);
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("Name", "LDGHT"));
            nameValuePairs.add(new BasicNameValuePair("Email", "hhh@example.com"));

            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            httppost.setEntity(new FileEntity(file, "video/mp4"));

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

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }

Check my Post for Sending Mutipart Data Post Data to Server with Multipart..

Thanks how to use this method "toByteArray()" for the video file — Dev, Oct 04 '11 at 08:57
Thanks, but it dose not work ,Do you think there is problem in version 2.3.3 to connect to the server ? — Dev, Oct 04 '11 at 11:29
@Dev That code is working copy of mine.. Surely it works.. Better post you full code here.. — Venky, Oct 04 '11 at 11:50
@Venky i tried your code i works perfectly , my question is that if i want to send other form data with video file ? — chhameed, Feb 14 '14 at 05:01

Unfortunately I was not successful to use Venky's code. After two day finally I found my solution and hope it helps those that have same problem. Feel free to modify the code since this code is based on my structure. Note: bitmapProfileImage is global variable that holds bitmap image (Bitmap bitmapProfileImage;)

public class ContentDownloader {

        public static String getHttpPutContent(String url, String token, MultipartEntity multipartEntity) {

            try {
                HttpClient httpClient = new DefaultHttpClient();
                HttpPut put = new HttpPut(url);
                put.setHeader("token", token);
    //            Log.i(TAG, "Token=> " + token);
                Log.i(TAG, "Try to open=> " + url);

                MultipartEntity reqEntity = multipartEntity;
                put.setEntity(reqEntity);

                HttpResponse httpResponse = httpClient.execute(put);
                int statusCode = httpResponse.getStatusLine().getStatusCode();
                Log.i(TAG, "Connection code: " + statusCode);

                HttpEntity entity = httpResponse.getEntity();
                String serverResponse = EntityUtils.toString(entity);
                Log.i(TAG, "Server response=> " + serverResponse);

                if(!isStatusOk(statusCode))
                    return null;

                return serverResponse;

            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (Exception e) {
                e.printStackTrace();
            }

            return null;
        } 

        /**
         *
         * @param statusCode
         * @return True if connection code is 2xx, False otherwise.
         */
        private static boolean isStatusOk(int statusCode) {
            if((statusCode >= HttpURLConnection.HTTP_OK)  &&  (statusCode <= HttpURLConnection.HTTP_PARTIAL))
                return true;

            return false;
        }
}

So in your activity/fragment you should have AsyncTask class. Add following code inside doInBackground method:

        @Override
        protected Integer doInBackground(Void... params) {
            String content = "";
            String url = LinkManager.getUserProfileUrl();

            Person person = SpStorage.getPersonInfo(context);

                String imgPath = SpStorage.getProfilePicPath(context);
                String imgName = imgPath.substring(imgPath.lastIndexOf("/") + 1);

                if(bitmapProfileImage == null) {
                    Log.i(TAG, "bitmap is null. Try to get it from profile pic directory...");
                    String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +
                            File.separator + ImageDownloader.DIRECTORY_NAME + File.separator + PROFILE_PICS;
                    imgPath = new File(file_path, imgName).getAbsolutePath();
                    bitmapProfileImage = BitmapFactory.decodeFile(imgPath);
                }

                if(bitmapProfileImage != null) {
                    Log.i(TAG, "Image address: " + imgPath);

                    try {
                        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
                        reqEntity.addPart("first_name", new StringBody(person.getName()));
                        reqEntity.addPart("last_name", new StringBody(""));
                        reqEntity.addPart("email",new StringBody(person.getEmail()));
                        reqEntity.addPart("birthday", new StringBody(person.getBirthDay()));
                        reqEntity.addPart("gender", new StringBody(person.getGender(person.getGender())));
                        reqEntity.addPart("orientation", new StringBody(person.getOrientation(person.getGender(), person.getLookingFor())));
                        reqEntity.addPart("relationship_status", new StringBody(person.getStatus(person.getStatus())));
                        reqEntity.addPart("city", new StringBody(person.getCity()));
                        reqEntity.addPart("about", new StringBody(person.getAboutMe()));
                        reqEntity.addPart("device_type", new StringBody("Android"));

                        ByteArrayOutputStream bos = new ByteArrayOutputStream();
                        bitmapProfileImage.compress(Bitmap.CompressFormat.PNG, 0, bos);
                        byte[] data = bos.toByteArray();
                        ByteArrayBody bab = new ByteArrayBody(data, "profilePic.png");
                        reqEntity.addPart("photo", bab);

                        content = ContentDownloader.getHttpPutContent(url, SpStorage.getToken(context), reqEntity);
                    }
                    catch (UnsupportedEncodingException e) {
                        e.printStackTrace();
                    }
                    catch (Exception e) {
                        e.printStackTrace();
                    }
                } else
                    Log.e(TAG, "Image not found :(");


            if(!TextUtils.isEmpty(content)) {
                return 0; // registration successful
            }

            return -1;
        }

Finally, in order to use MultipartEntity, You are needed to download 4 jar files. One is apache-mime4j and the rest are httpclient, httpcore and httpmime. You should extract jar files and copy/paste it int ./libs folder of your project.

There is my working solution (I hope simpler) for sending image with post, using apache http libraries (very important here is boundary add It won't work without it in my connection). I hope it could help in such situation:

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
            byte[] imageBytes = baos.toByteArray();

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(StaticData.AMBAJE_SERVER_URL + StaticData.AMBAJE_ADD_AMBAJ_TO_GROUP);

            String boundary = "-------------" + System.currentTimeMillis();

            httpPost.setHeader("Content-type", "multipart/form-data; boundary="+boundary);

            ByteArrayBody bab = new ByteArrayBody(imageBytes, "pic.png");
            StringBody sbOwner = new StringBody(StaticData.loggedUserId, ContentType.TEXT_PLAIN);
            StringBody sbGroup = new StringBody("group", ContentType.TEXT_PLAIN);

            HttpEntity entity = MultipartEntityBuilder.create()
                    .setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
                    .setBoundary(boundary)
                    .addPart("group", sbGroup)
                    .addPart("owner", sbOwner)
                    .addPart("image", bab)
                    .build();

            httpPost.setEntity(entity);

            try {
                HttpResponse response = httpclient.execute(httpPost);
                ...then reading response

the boundary tidbit helped me solve a very similar issue. you saved me a great deal of grief. — nserror, Feb 29 '16 at 21:15
