What is the reason of this error java.io.IOException: Content-Length and stream length disagree

Question

I am getting this error

   java.io.IOException: Content-Length and stream length disagree

on this line of code return response.body().bytes();

this is full code

edit: after some google the reason of the error is from okhttp lib

if (contentLength != -1L && contentLength != bytes.size.toLong()) {
  throw IOException(
      "Content-Length ($contentLength) and stream length (${bytes.size}) disagree")
}

but how to fix that ?

edit:

this is full code:

public class OkHttpHandler extends AsyncTask<Void, Void, byte[]> {

    private final String Fetch_URL = "http://justedhak.comlu.com/get-data.php";
    ArrayList<Listitem> Listitem;

        builder.url(Fetch_URL);

        Request request = builder.build();

        String result = null;
        try {

            Response response = httpClient.newCall(request).execute();
          //  int statusCode = response.getStatusLine().getStatusCode();

              int statusCode =200;

           // HttpEntity entity = response.body().byteStream();
            if (statusCode == 200) {
                byte[] buffer = new byte[8192];

        } catch (JSONException e) {

Answer 1

That Exception thrown because you have called InputStream inputStream = response.body().byteStream(); then called response.body().bytes(); again.

You can use return bytes array from the inputStream or return result.getBytes(); instead if that is what you want to return.

From inputStream to bytes refer to the following:

    public byte[] getBytesFromInputStream(InputStream inputStream) throws IOException {
        try {            
            byte[] buffer = new byte[8192];
            int bytesRead;
            ByteArrayOutputStream output = new ByteArrayOutputStream();
            while ((bytesRead = inputStream.read(buffer)) != -1) {
                output.write(buffer, 0, bytesRead);
            }
            return output.toByteArray();
        } catch (OutOfMemoryError error) {
            return null;
        }
    }

If you debug at ResponseBody.class, you will see as the following screenshot:
