For full detail please have a look on my post Click here

its quite difficult to send multiple images to server using MultipartEntity. I did search for this but didn't find any right solution then i made my own way to send multiple images to server , here i send array of selected paths to asynctask and in asynctask i sent images to server

Calling Asysnctask Function- new Upload_Multiple.excute(Array_of_Path[]))

    Private class Upload_Multiple_img extends AsyncTask {

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();

    }

    protected String doInBackground(String... paths_array) {



        String data = "";

        for (int i = 0; i < paths_array.length; i++) {

            //  get_Picture_bitmap() returns bitmap by passing path of image 
             //   get_Picture_bitmap() is mentioned below. 
            Bitmap bitmap = get_Picture_bitmap(paths_array[i]);

            ByteArrayOutputStream stream = new ByteArrayOutputStream();

            bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
            InputStream in = new ByteArrayInputStream(stream.toByteArray()); // convert

            DefaultHttpClient httpclient = new DefaultHttpClient();

            String server_funtion_url="...serveraddres"+funtion_at_server"";
            HttpPost httppost = new HttpPost(server_funtion_url); // server

            MultipartEntity reqEntity = new MultipartEntity();

            obj_SP = ImagePicker.this.getSharedPreferences("Eperty", 0);

            String id_prop = obj_SP.getString("new_prop_id", "");

            String Image_Name =
                    + String.valueOf(System.currentTimeMillis()) + ".jpg";
// image is a key which is used at server end to get this 
            reqEntity.addPart("image", Image_Name, in);

            httppost.setEntity(reqEntity);

            HttpResponse response = null;
            try {
                response = httpclient.execute(httppost);
                data = EntityUtils.toString(response.getEntity());
                System.out.println("FFFF== " + data);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();

            }

        }

        return data;
    }

    @Override
    protected void onProgressUpdate(Void... values) {

        super.onProgressUpdate(values);
    }

    @Override
    protected void onPostExecute(String result) {

        ConstantData.ToastAlert(ImagePicker.this,
                "Images Uploaded successfully");

    }
}

//);

• For compressing the images and getting bitmap for i made below funtion*

      matrix.postRotate(180);
      bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
