How send String Array in MultipartEntity

Try this code..

private class webAsync extends AsyncTask<String, Integer, String> {

    private ProgressDialog pb = null;
    private HttpResponse httpResponse;
    private HttpPost postRequest;
    private HttpClient httpClient;
    private HttpEntity httpEntity;
    String Str_imagepath="path file";

    @Override
    protected String doInBackground(String... params) {



        String APP_SERVICE_DOMAIN = null;
        String mIncomingUrl = null;

            APP_SERVICE_DOMAIN = "URL webservice";

        mIncomingUrl = APP_SERVICE_DOMAIN;// add the field if any




        System.out.println("@Incoming Request URL ==" + mIncomingUrl);
        try {

            HttpPost httppost = new HttpPost(mIncomingUrl);

            MultipartEntity entity = new MultipartEntity();
            File myFile = new File(Str_imagepath);
            Log.e("TAG_FILE", "Exists1 " + myFile.exists());

            FileBody fileBody = new FileBody(myFile);
            if(myFile.exists()) {
                entity.addPart("image", fileBody);

     // webservice parameter for file
            }
      for (String mArray: mSelectedCategoryArray)
      {
     entity .addPart("ArrayID[]", new StringBody(mArray));
      } 

            httppost.setEntity(entity);
            HttpClient httpclient = new DefaultHttpClient();
            HttpResponse httpresponse = httpclient.execute(httppost);
            if (httpresponse.getEntity() != null) {
                String fileResponse = EntityUtils.toString(httpresponse
                        .getEntity());
                System.out.println("@@............." + fileResponse);



                return fileResponse;
            }
