How can I get content length from responses header?

Question

I'm using this code for fetching data from a URL using AsyncTask:

 protected String doInBackground(Object... params) {
    int ResponseCode=-1;
    try {
        URL myURL=new URL("URL...");
        HttpURLConnection connection=(HttpURLConnection) myURL.openConnection();
        connection.connect();
        ResponseCode=connection.getResponseCode();

        if (ResponseCode==HttpURLConnection.HTTP_OK) {
            InputStream inputStream=connection.getInputStream();
            Reader reader=new InputStreamReader(inputStream);
            int contentLength=connection.getContentLength();
            char[] charArray=new char[contentLength];
            reader.read(charArray);
            String responseData=new String(charArray);
            Log.i("TAG", responseData);
            Log.i("TAG", ""+contentLength);
        }
        else {
            Log.i("TAG", " Unsuccessful HTTP Response Code: "+ResponseCode);
        }

    }catch (MalformedURLException e) {
            Log.i("TAG", "MalformedURLException Error: "+e.getMessage());
    } catch (IOException e) {
            Log.i("TAG", "IOException Error: "+e.getMessage());
    } catch (Exception e) {
            Log.i("TAG", "Exception Error: "+e);
    }
    return " "+ResponseCode;
}

above code works fine and I use it in some projects, but for URL that I'm working on, it doesn't work and always return -1 for Response Code,because the HTTP response of my URL doesn't contain Content-Length header, the content is chunked., now I wanna know Is there any equivalent way to do that?
Thanks in advanced

Answer 1

finally I solved my problem this way :

try {
     URL blogPostURL=new URL("URL...");
     URLConnection connection=blogPostURL.openConnection();
     BufferedReader reader=new BufferedReader(new InputStreamReader(connection.getInputStream()));
     String responseData;
     while ((responseData = reader.readLine()) != null){ 
             Log.i("TAG", responseData);
     }
     reader.close();
}catch (MalformedURLException e) {
     Log.i("TAG", "MalformedURLException Error: "+e.getMessage());
} catch (IOException e) {
     Log.i("TAG", "IOException Error: "+e.getMessage());
} catch (Exception e) {
     Log.i("TAG", "Exception Error: "+e);
}
