java.lang.IllegalStateException when sending JSON to webservice using HttpResponse

Question

I'm trying to pass a JSON data object to a webservice in my Android Application. I've a button and when i click on it I want to send the location to my webservice. Everything works fine untill the last command. I've got my code from another post here : How to post data to a Webservice using JSON?

It should be work so I think the problem is somewhere else but the error says nothing to me.. this is my function that runs on onclick:

public void clickbuttonRecieve(View v) {
         new MyAsync().execute();
 }


 private class MyAsync extends AsyncTask<Void, Void, Void> {
        protected Void doInBackground(Void... tmps) {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(
                    "http://bomatec.be/webservice2.php");

            httpPost.setHeader("content-type", "application/json");
            JSONObject data = new JSONObject();
            try {
                String message;

                data.put("user", "12");
                data.put("lat", "50.8");
                data.put("lng", "4.3");


            }catch (JSONException e) {
                Log.e("MYAPP", "unexpected JSON exception", e);
            }

            try {
                StringEntity entity = new StringEntity(data.toString(), HTTP.UTF_8);
                httpPost.setEntity(entity);
            }catch(java.io.UnsupportedEncodingException e){
                Log.e("MYAPP", "UnsupportedEncodingException JSON exception", e);
            }


            try {
                HttpResponse response = httpClient.execute(httpPost);
            }catch (IOException e){
                Log.e("MYAPP", "IOException", e);
            }
            return null;
        }
    }

You have NetworkOnMainThreadException exception, you must put your onClick code into AsyncTask. Android prohibits network operations on UI thread, this is to prevent blocking main UI message queue.

Example code is:

 private class MyAsync extends AsyncTask<Void, Void, Void> {
     protected Void doInBackground(Void... tmps) {
         // do your work here!!
         return null;
     }
 }

in your onclick - execute: new MyAsync().execute()

I have no knowledge of AsyncTask. Is it 'total' different? – user5488652 Dec 25 '15 at 22:33
@user5488652 read docs: http://developer.android.com/reference/android/os/AsyncTask.html – marcinj Dec 25 '15 at 22:34
I changed my code. Still get same error, you can see my code at original question. Thanks for your help – user5488652 Dec 25 '15 at 22:46
@user5488652 you should learn to read LogCat - you need to add permission to access internet - `java.lang.SecurityException: Permission denied (missing INTERNET permission?)` Add `` to your manifest. – marcinj Dec 25 '15 at 22:49
Also - HttpClient was depracated, you should use Url – marcinj Dec 25 '15 at 22:50
Thx for your help! It works now. I've got one more question. The AsyncTask keeps running, do you know why he does that? – user5488652 Dec 25 '15 at 23:18
That's just the task of an AsyncTask I assume – user5488652 Dec 25 '15 at 23:21
AsyncTask is based on thread pool, so if you ask why its thread still exists after AsyncTask finished - then its because it will get reused for next AsyncTask. – marcinj Dec 25 '15 at 23:22
