How to send JSON and audio MP3 file using HttpClient POST in Java

I am using HttpClient to send a request with JSON and MP3 audio content. Can anybody tell me where the below code goes wrong? I am using HttpClient version 4.5.2.
HttpClient httpClient = HttpClientBuilder.create().setUserAgent("MyAgent").setMaxConnPerRoute(4).build();
HttpPost httpPostRequest = new HttpPost("url");
httpPostRequest.addHeader("content-type","multipart/form-data");
File audioFile = new File("filename.mp3");
FileBody fileBody = new FileBody(audioFile);
StringBody jsonStringBody = new StringBody(gson.toJson(pojoObject).toString(), ContentType.MULTIPART_FORM_DATA);
MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntityBuilder.setContentType(ContentType.MULTIPART_FORM_DATA);
multipartEntityBuilder.addPart("file", fileBody);
multipartEntityBuilder.addPart("jsonMetaData", jsonStringBody);
HttpEntity entity = multipartEntityBuilder.build();
httpPostRequest.setEntity(entity);
HttpResponse response = httpClient.execute(httpPostRequest);

Uploading file using apache httpclient

I am trying to write a program in android that uploads a file to server. I want to use apache httpclient for that.
Here is my code:
String url = "http://192.168.1.103:8080";
File file = new File("/sdcard/alireza/ali.txt");
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true); // Send in multiple parts if needed
httppost.setEntity(reqEntity);
Toast.makeText(getApplicationContext(),"executing...",Toast.LENGTH_LONG).show();
HttpResponse response = httpclient.execute(httppost);
Toast.makeText(getApplicationContext(),"done",Toast.LENGTH_LONG).show();
//Do something with response...
}catch (Exception e){
}
The done toast doesn't appear.

Uploading File to server taking Long Time Android

I have developed application where I am sending audio file and receiver information to server, Its working but many times uploading takes very long time and cause ConnectionTimeout exception.
Code I am using now:
BasicHttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, 120000);
HttpConnectionParams.setSoTimeout(httpParameters, 120000);
HttpClient httpClient = new DefaultHttpClient(httpParameters);
postStr = new Gson().toJson(audioBean);
File file = new File(audioBean.getFilePath());
ContentBody contentBody = new FileBody(file, "audio/wav");
MultipartEntity mpEntity = new MultipartEntity();
mpEntity.addPart("audio", new StringBody(postStr));
mpEntity.addPart("file", contentBody);
httpPost.setEntity(mpEntity);
HttpResponse httpResponse = httpClient.execute(httpPost);
inputStream = httpResponse.getEntity().getContent();
above code runs in thread, please tell me how to improve performance

httpclient.execute(httppost) doesn't work？

I use httpclient to post img to website.
But I have tucked it into httpclient.execute(httppost).
In my local environment , I run it perfect. But when i publish project to SinaAppEngine（Java Local IO
restricted）->sae ,execute method doesn't work because code like this:
reqEntity.addPart("image", byteArrayBody);
(Stringbody run normally )
My sample code:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://r.catchoom.com/v1/search");
ByteArrayBody byteArrayBody = new ByteArrayBody(imgByte, "test.jpg");
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("image", byteArrayBody);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);

java- unknown host exception when using apache http client

I am trying to make a simple GET request for a website, but I am getting unknown host exception.
Given below is my code--
DefaultHttpClient client = new DefaultHttpClient();
HttpHost targetHost=null;
targetHost= new HttpHost("google.com/", 80, "http");
HttpGet httpget = new HttpGet("about-us.html");
BasicHttpContext localcontext = new BasicHttpContext();
try {
HttpResponse response = client.execute(targetHost, httpget, localcontext);

It looks like you have a simple problem here.
The URL for your 'HttpHost' object is malformed. You need to drop the '/' from "google.com/".
It should work after that. I used your code with that single modification & it worked.
DefaultHttpClient client = new DefaultHttpClient();
HttpHost targetHost = new HttpHost("google.com", 80, "http");
HttpGet httpget = new HttpGet("about-us.html");
BasicHttpContext localContext = new BasicHttpContext();
HttpResponse response = null;
try { response = client.execute(targetHost, httpget, localContext);
System.out.println(response.getStatusLine()
}
catch(Exception e){
// Enter error-handling code here.
}
