File upload using MultipartEntityBuilder gives an Error

Issue

In my android app I'm using AsyncTask to upload a file to the backend. In there I use MultipartEntityBuilder in my doInBackground method. my doInBackground part is as follows,

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

    try {
        String serverLoaction = params[0];
        String filePath = params[1];

        HttpClient httpClient = new DefaultHttpClient();
        HttpContext localContext = new BasicHttpContext();
        HttpPost httpPost = new HttpPost(serverLoaction);

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

        FileBody fileBody = new FileBody(new File(filePath));
        StringBody stringBody = new StringBody("data", ContentType.MULTIPART_FORM_DATA);

        builder.addPart("file", fileBody);
        builder.addPart("name", stringBody);

        httpPost.setEntity(builder.build());

        HttpResponse response = httpClient.execute(httpPost, localContext);

        BufferedReader reader = new BufferedReader(
                new InputStreamReader(
                        response.getEntity().getContent(), "UTF-8"));

        String sResponse = reader.readLine();
        return sResponse;

    } catch (Exception e) {
        if (dialog.isShowing())
            dialog.dismiss();
        Toast.makeText(getApplicationContext(), "Error in downloading image", Toast.LENGTH_LONG).show();
        Log.e(e.getClass().getName(), e.getMessage(), e);
        return null;
    }
}

This show me no syntax errors. but when I run the code an exception throws and the app stops. the error log is as below.

it tells NoSuchFieldError exception raises, but I go through several tutorials and it's seems to me the code is ok according to them. the line number points to where the error occurs is points to

httpPost.setEntity(builder.build());

line. so whats the problem with this code segment and how can I fix this. thanks and regards!

Solution

I think this is due to library which you are using in your build.gradle file. Please check with below code once

compile('org.apache.httpcomponents:httpmime:4.3.6') {
exclude module: 'httpclient'
}
compile 'org.apache.httpcomponents:httpclient-android:4.3.5'
