How to send Http post request to wit.ai

Question

Since Wit.AI API for android is deprecated i'm trying to use its http api to get a result in json from my wit.ai app. I don't know if it's possible but i'm trying to send an http request from my android app in this way:

public class MainActivity extends AppCompatActivity {

String addressM = "https://api.wit.ai/message?v=20160526";
String accessToken = "BODF5LOCAIPJZI37KTWQKELNUR26ZMDH";
String header = "Authorization: Bearer ";
String query = "q";
String message = "partita";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    CallAPI runner = new CallAPI();
    runner.execute(addressM);
}

public class CallAPI extends AsyncTask<String, String, String> {

    public CallAPI() {
        //set context variables if required
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }


    @Override
    protected String doInBackground(String... params) {
        System.out.println("Running........................");

        String urlString = params[0]; // URL to call
        String resultToDisplay = "";

        InputStream in = null;
        try {

            URL url = new URL(urlString);

            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestProperty(header, accessToken);
            urlConnection.setRequestMethod("POST");
            urlConnection.setRequestProperty(query, message);
            in = new BufferedInputStream(urlConnection.getInputStream());


        } catch (Exception e) {

            System.out.println(e.getMessage());

            return e.getMessage();

        }

        try {
            resultToDisplay = IOUtils.toString(in, "UTF-8");
            //to [convert][1] byte stream to a string
        } catch (IOException e) {
            e.printStackTrace();
        }
        return resultToDisplay;
    }


    @Override
    protected void onPostExecute(String result) {
        //Update the UI
    }
}

I'm following this doc and i'm trying to send a simple "message request". So, i have to put a header in my url containing my auth token and then put my request in it. When sending my request i should get back a json and also an inbox message in my wit.ai app, but i'm not gettin anything (at the moment i don't really care for the json, but just for the inbox message to be sure my request has been sent). I copied the above code from another stack overflow question. I set my manifest correctly with internet permissions. Can someone help me?

Have you tried to use something like Retrofit? Or just OkHttp? They make POST requests easier, plus no need for AsyncTask — OneCricketeer, Jun 10 '16 at 13:59
If not, then your code is doing nothing with the potential result you are reading back from the server... So, maybe try putting some code into onPostExecute — OneCricketeer, Jun 10 '16 at 14:01
So couldnt do it in the way you told me, but i found this http://stackoverflow.com/questions/35358232/wit-ai-how-to-send-request-in-java, and it should work, i'm trying to get a result now — Lucas, Jun 10 '16 at 15:05
Don't focus on "wit.ai" so much. All you need to understand is how to [make a POST request](http://stackoverflow.com/questions/4205980/java-sending-http-parameters-via-post-method-easily). Which is simpler with [OkHttp](https://github.com/square/okhttp/wiki/Recipes#posting-form-parameters) — OneCricketeer, Jun 10 '16 at 15:10
Also, too late now, but you should have removed your access token from the code before you posted it — OneCricketeer, Jun 10 '16 at 15:11

Change lines 4,5 to these:

String accessToken = "Bearer BODF5LOCAIPJZI37KTWQKELNUR26ZMDH";
String header = "Authorization";

And it should work.
