what is the standard way to post JSON Object along with file using MultipartEntityBuilder and HTTP Client in Android

I found the solution,we can split the json object like following and send as a key value

  multipartEntity.addPart("data[Asset][file]", new FileBody(file,                            ContentType.APPLICATION_OCTET_STREAM, "filename.png"));                    multipartEntity.addTextBody("data[Person][first]", "kk");                    multipartEntity.addTextBody("data[Person][email]",                            "rajesh123458@gmail.com");                    multipartEntity.addTextBody("data[Person][birthdate]",                            "1984-01-01");                    multipartEntity.addTextBody("data[Person][Account][username]",                            "savita123458");                    multipartEntity.addTextBody("data[Person][Account][password]",                            "testuser12345678");        httppost.setEntity(multipartEntity.build());                    try {                        HttpResponse response = httpclient.execute(httppost);                        Log.d("status", response.getStatusLine().toString());                        Log.d("data", EntityUtils.toString(response.getEntity()));                    } catch (ClientProtocolException e) {                        e.printStackTrace();                    } catch (IOException e) {                        e.printStackTrace(); // TODO Auto-generated catch block                    }

I have done something similar using http://loopj.com/android-async-http/, which can be used synchronously in your thread

Try doing this.

multipartEntity.addBinaryBody("file", file, ContentType.create("application/octet-stream"), file.getName());multipartEntity.addTextBody("json", jsonobject.toString(),  ContentType.DEFAULT_BINARY);httppost.setEntity(multipartEntity.build());
