My code is the next:

class sampleService extends AsyncTask<Boolean, Boolean, Boolean> {

        @Override
        protected Boolean doInBackground(Boolean... params) {
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet del = new HttpGet("192.168.1.68:8000/c_f/4.0");
            del.setHeader("content-type", "application/json");
            try {
                HttpResponse resp = httpClient.execute(del);
                String respStr = EntityUtils.toString(resp.getEntity());
                JSONObject respJSON = new JSONObject(respStr);
                String far = respJSON.getString ("far"); //Check your type data to return in your web service.


                System.out.println("HOLAAAAAAAAAAAAAAAAAAAAAA" + far);
                Log.d("Service", far);
            } catch(Exception ex) {
                Log.e("Service","Error!", ex);
            }
            return null;
        }

If I get the http:// it says "Connection refused": When I use it in a Web Browser it works perfectly And I get the JSON response. But then I get the NEXT ERROR:

Answer 1

Your URI isn't valid, as it is missing the protocol. if you append http:// on the front, it should work correctly

In response to your update, you should learn to read the LogCat properly.

Lines that say Caused by: are ones to look for, as they will usually tell you the root cause of the issue. In this case, a quick google for the exception you posted brings up many Stack Overflow answers that would fix your question.

Answer 2

Your Url is bad formed, you need defin "htttp://"

http://192.168.1.68:8000/c_f/4.0
