Question

Error:org.apache.http.conn.HttpHostConnectException: Connection to http://10.0.2.2:8080 refused When Android consumes rest api in php, and I connect to the api

I use eclipse and my android phone via usb to run my app . My api rest is made in php and use xampp and it run on port 8080 http://localhost:8080 . Xampp works with my other web application , but Android does not work.

 -Also, my phone and my computer are not connected to the same network. -rest api can work in this case without internet?

My code in android is this :

 private class TareaWSInsertar extends AsyncTask<String,Integer,Boolean> {
        //agregado user_id, user_fullname, user_email
        private int user_id;
        private String user_fullname;
        private  String user_email;

        protected Boolean doInBackground(String... params) {
            boolean resul = true;

            HttpClient httpClient = new DefaultHttpClient();


            HttpPost post = new HttpPost("http://10.0.2.2:8080/rest/login/");
        post.setHeader("content-type", "application/json");

        try
            {
            //Construimos el objeto cliente en formato JSON
            JSONObject dato = new JSONObject();


            dato.put("email", params[0]);
            dato.put("pwd", params[1]);

            StringEntity entity = new StringEntity(dato.toString());
            post.setEntity(entity);

                HttpResponse resp = httpClient.execute(post);
                String respStr = EntityUtils.toString(resp.getEntity());

                JSONObject respJSON = new JSONObject(respStr);

                user_id = respJSON.getInt("user_id");
                user_fullname = respJSON.getString(user_fullname);
                user_email = respJSON.getString("user_email");


                if(!respStr.equals("true"))
                    resul = false;
            }
            catch(Exception ex)
            {
                Log.e("ServicioRest","Error!", ex);
                resul = false;
            }

            return resul;
        }

            protected void onPostExecute(Boolean result) {

            if (result)
            {
             Toast.makeText(getApplicationContext(), "" + user_id+ "-" +    user_fullname + "-" + user_email, Toast.LENGTH_LONG).show();
            }
        }
    }

I have tried different way :

http://10.0.2.2:8080/rest/login
 http://localhost:8080/rest/login
 http:/127.0.0.1:8080/rest/login

Note: I read that http://10.0.2.2 only works when the android emulator is used, I use my phone connected via usb .

but nothing works , even <uses-permission android:name="android.permission.INTERNET"/> I added in my manifest .

Sorry help me!!, PD: I do not speak English

Answer 1

First you have an error:

 HttpPost post = new HttpPost ( " http:/127.0.0.1:8080/rest/login/ "); 

should be:

HttpPost post = new HttpPost ( " http://127.0.0.1:8080/rest/login/ ");

Next if the phone is not connected to your coputer network it wont ever connect to your local server aka your computer.

If you have a wifi connection at your home check the ip address of the computer which runs xampp and replace it with localhost. If there is no wifi connection and your computer if connected to your modem (without router) then just check your ip address here and replace it with localhost.

I managed to fix this problem by writing my IP address from cmd -> ipconfig in the url:

HttpPost post = new HttpPost("http://192.168.x.x/rest/login/");
