ISSUE

When I am using this above API request in Advanced RestClient then I am getting the response shown above but when trying to achieve this by using OkHttpClient library in the android application but getting the following error:

Here is the code spi.net using OkHttpClient:

private void captureRdRequest(final String pidOpt, final String reqUrl) {

    String pidOpt = "<PidOptions ver=\"1.0\"><Opts fCount=\"1\" fType=\"0\" iCount=\"\" iType=\"\" pCount=\"\" pType=\"\" format=\"1\" pidVer=\"2.0\" timeout=\"10000\" otp=\"\" wadh=\"$WADH\" posh=\"\"/></PidOptions>";
    String url = "http://127.0.0.1:42200/capture";

    Thread thread = new Thread(new Runnable() {

        @Override
        public void run() {
            try  {

                OkHttpClient client = new OkHttpClient().newBuilder()
                        .build();
                MediaType mediaType = MediaType.parse("text/xml");
                RequestBody body = RequestBody.create(mediaType, pidOpt);
                okhttp3.Request request = new okhttp3.Request.Builder()
                        .url(url)
                        .method("CAPTURE", body)
                        .addHeader("Content-Type", "text/xml")
                        .addHeader("Accept", "text/xml")
                        .build();
                okhttp3.Response response = client.newCall(request).execute();
                Log.d("sdf", response.toString());

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });

    thread.start();

}
