Android multipart file upload with OkHttp

I am using this for audio records and video file and it is working but i want to replace it with OkHttp. I didnt figure it out. Can anyone help me about it?
public class HttpMultipartUpload {
static String lineEnd = "\r\n";
static String twoHyphens = "--";
static String boundary = "AaB03x87yxdkjnxvi7";
public static String upload(URL url, File file, String fileParameterName, HashMap<String, String> parameters)
throws IOException {
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream dis = null;
FileInputStream fileInputStream = null;
byte[] buffer;
int maxBufferSize = 20 * 1024;
try {
//------------------ CLIENT REQUEST
fileInputStream = new FileInputStream(file);
// open a URL connection to the Servlet
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
// Allow Inputs
conn.setDoInput(true);
// Allow Outputs
conn.setDoOutput(true);
// Don't use a cached copy.
conn.setUseCaches(false);
// Use a post method.
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"" + fileParameterName
+ "\"; filename=\"" + file.toString() + "\"" + lineEnd);
dos.writeBytes("Content-Type: text/xml" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
buffer = new byte[Math.min((int) file.length(), maxBufferSize)];
int length;
// read file and write it into form...
while ((length = fileInputStream.read(buffer)) != -1) {
dos.write(buffer, 0, length);
}
for (String name : parameters.keySet()) {
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"" + name + "\"" + lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(parameters.get(name));
}
// send multipart form data necessary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
dos.flush();
} finally {
if (fileInputStream != null) fileInputStream.close();
if (dos != null) dos.close();
}
//------------------ read the SERVER RESPONSE
try {
dis = new DataInputStream(conn.getInputStream());
StringBuilder response = new StringBuilder();
String line;
while ((line = dis.readLine()) != null) {
response.append(line).append('\n');
}
return response.toString();
} finally {
if (dis != null) dis.close();
}
}
}
How can I change it with OkHttp. Any code please. I dont have good knowledge about on OkHttp. I was using (HttpURLConnection) but it seems not effective now.

See the documentation example on posting form data
https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PostMultipart.java
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("title", "Square Logo")
.addFormDataPart("image", "logo-square.png",
RequestBody.create(
new File("docs/images/logo-square.png"),
MEDIA_TYPE_PNG))
.build();
Request request = new Request.Builder()
.header("Authorization", "Client-ID " + IMGUR_CLIENT_ID)
.url("https://api.imgur.com/3/image")
.post(requestBody)
.build();

java httpurlconnection "failed to read: line to long:"

I'm using httpurlconnection for uploading files to different servers.
For some hosts the following code is working and I'm able to upload files, but when I'm trying to upload to another host, I get an error message

The problem is here. The line terminator in HTTP is defined as \r\n, not \n.

the average REST webservice won't return a response body on POST/PUT, just a response status. You'd like to determine it instead of the body.
Replace
InputStream response = conn.getInputStream();
by
int status = conn.getResponseCode();
All available status codes and their meaning are available in the HTTP spec, as linked before. The webservice itself should also come along with some documentation which overviews all status codes supported by the webservice and their special meaning, if any.
If the status starts with 4nn or 5nn, you'd like to use getErrorStream() instead to read the response body which may contain the error details.
InputStream error = con.getErrorStream();

Error:415 HttpURLConnection

I want to connect to a web-service and send a big file, i use HttpURLConnection like this:
private void doFileUpload() {

I cant use ksoap2 because i need to send a very large file and this causes OutOfMemoryError. That's why i need to use this class.
I'm getting error 415, what am i doing wrong ?

Try using:
conn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
You are sending xml, I guess the server expects it.
