Square`s OkHttp. Download progress

Question

Is there any way to get downloading file progress when using square`s OkHttp?

I did not find any solution in Recipes.

They have class Call which can get content asynchronically, but there is no method to get current progress.

Oops answer was obvious. Sorry for dumb question. Just need to read InputStream as usual.

private class AsyncDownloader extends AsyncTask<Void, Long, Boolean> {
    private final String URL = "file_url";

    @Override
    protected Boolean doInBackground(Void... params) {
        OkHttpClient httpClient = new OkHttpClient();
        Call call = httpClient.newCall(new Request.Builder().url(URL).get().build());
        try {
            Response response = call.execute();
            if (response.code() == 200) {
                InputStream inputStream = null;
                try {
                    inputStream = response.body().byteStream();
                    byte[] buff = new byte[1024 * 4];
                    long downloaded = 0;
                    long target = response.body().contentLength();

                    publishProgress(0L, target);
                    while (true) {
                        int readed = inputStream.read(buff);
                        if(readed == -1){
                            break;
                        }
                        //write buff
                        downloaded += readed;
                        publishProgress(downloaded, target);
                        if (isCancelled()) {
                            return false;
                        }
                    }
                    return downloaded == target;
                } catch (IOException ignore) {
                    return false;
                } finally {
                    if (inputStream != null) {
                        inputStream.close();
                    }
                }
            } else {
                return false;
            }
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
    }

    @Override
    protected void onProgressUpdate(Long... values) {
        progressBar.setMax(values[1].intValue());
        progressBar.setProgress(values[0].intValue());

        textViewProgress.setText(String.format("%d / %d", values[0], values[1]));
    }

    @Override
    protected void onPostExecute(Boolean result) {
        textViewStatus.setText(result ? "Downloaded" : "Failed");
    }
}
