Download binary file from OKHTTP

Question

I am using OKHTTP client for networking in my android application.

This example shows how to upload binary file. I would like to know how to get inputstream of binary file downloading with OKHTTP client.

Here is the listing of the example :

public class InputStreamRequestBody extends RequestBody {

    private InputStream inputStream;
    private MediaType mediaType;

    public static RequestBody create(final MediaType mediaType, 
            final InputStream inputStream) {
        return new InputStreamRequestBody(inputStream, mediaType);
    }

    private InputStreamRequestBody(InputStream inputStream, MediaType mediaType) {
        this.inputStream = inputStream;
        this.mediaType = mediaType;
    }

    @Override
    public MediaType contentType() {
        return mediaType;
    }

    @Override
    public long contentLength() {
        try {
            return inputStream.available();
        } catch (IOException e) {
            return 0;
        }
    }

    @Override
    public void writeTo(BufferedSink sink) throws IOException {
        Source source = null;
        try {
            source = Okio.source(inputStream);
            sink.writeAll(source);
        } finally {
            Util.closeQuietly(source);
        }
    }
}

Current code for simple get request is:

OkHttpClient client = new OkHttpClient();
request = new Request.Builder().url("URL string here")
                    .addHeader("X-CSRFToken", csrftoken)
                    .addHeader("Content-Type", "application/json")
                    .build();
response = getClient().newCall(request).execute();

Now how do I convert the response to InputStream. Something similar to response from Apache HTTP Client like this for OkHttp response:

InputStream is = response.getEntity().getContent();

---

EDIT

Accepted answer from below. My modified code:

request = new Request.Builder().url(urlString).build();
response = getClient().newCall(request).execute();

InputStream is = response.body().byteStream();

BufferedInputStream input = new BufferedInputStream(is);
OutputStream output = new FileOutputStream(file);

byte[] data = new byte[1024];

long total = 0;

while ((count = input.read(data)) != -1) {
    total += count;
    output.write(data, 0, count);
}

output.flush();
output.close();
input.close();

Getting ByteStream from OKHTTP

I've been digging around in the Documentation of OkHttp you need to go this way

use this method :

response.body().byteStream() wich will return an InputStream

so you can simply use a BufferedReader or any other alternative

OkHttpClient client = new OkHttpClient();
request = new Request.Builder().url("URL string here")
                     .addHeader("X-CSRFToken", csrftoken)
                     .addHeader("Content-Type", "application/json")
                     .build();
response = getClient().newCall(request).execute();

InputStream in = response.body().byteStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String result, line = reader.readLine();
result = line;
while((line = reader.readLine()) != null) {
    result += line;
}
System.out.println(result);
response.body().close();
