POST method is not set

During debug, I realize that all the request property and method I set is not executed at all. Can anyone explain why?

Because of this, whenever I request an output from URLConnection, that line will create a runtime error.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    try {
        url = new URL("https://ussouthcentral.services.azureml.net/workspaces/80b0369fe0df48308d956e2ddce52806/services/6379155db28f4c91b84e78d268a927f9/execute?api-version=2.0&format=swagger");
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    try {
        urlConnection = (URLConnection) url.openConnection();
        urlConnection.setDoOutput(true);
       // urlConnection.setRequestMethod("POST");

        String api_key = "Bearer api_key";
        urlConnection.setDoInput(true);

        urlConnection.addRequestProperty("Authorization", api_key);
        urlConnection.addRequestProperty("Content-Type", "application/json");
        urlConnection.addRequestProperty("Accept", "application/json");
         } catch (IOException e) {
        e.printStackTrace();
    }

   try {
        urlConnection.connect();
        urlConnection.getContent();
    } catch (IOException e) {
        e.printStackTrace();
    }

  1. sending a network request in Activity.onCreate will crash your app with a NetworkOnMainThreadException, you should never do that

  2. I strongly suggest using other networking libraries which will take care of most of the things you're struggling with here such as OkHttp, Volley or Retrofit

First of all you are doing network operations on UI thread which android OS does not allow so, you should put your code in an async task

like so : 

AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {
            URL url = null;
            URLConnection urlConnection = null;
            try {
                url = new URL("https://ussouthcentral.services.azureml.net/workspaces/80b0369fe0df48308d956e2ddce52806/services/6379155db28f4c91b84e78d268a927f9/execute?api-version=2.0&format=swagger");
                urlConnection = (URLConnection) url.openConnection();
                urlConnection.setDoOutput(true);
                // urlConnection.setRequestMethod("POST");

                String api_key = "Bearer api_key";
                urlConnection.setDoInput(true);

                urlConnection.addRequestProperty("Authorization", api_key);
                urlConnection.addRequestProperty("Content-Type", "application/json");
                urlConnection.addRequestProperty("Accept", "application/json");
                urlConnection.connect();
                urlConnection.getContent();
            }
            catch (IOException exc) {
                exc.printStackTrace();
            }
            return null;
        }
    };

    task.execute();

also make sure you have intenet permission in the manifest 

<uses-permission android:name="android.permission.INTERNET" />

also your api key "Bearer api_key" is not a valid api key

} catch (MalformedURLException e) {
    e.printStackTrace();
}
try {
    String requestBody = "api-version=2.0&format=swagger"
    urlConnection = (URLConnection) url.openConnection();
    String api_key = "Bearer api_key";

    urlConnection.addRequestProperty("Authorization", api_key);
    urlConnection.addRequestProperty("Content-Type", "application/json");
    urlConnection.addRequestProperty("Accept", "application/json");
    urlConnection.setDoOutput(true);
    OutputStreamWriter writer = new OutputStreamWriter(urlConnection.getOutputStream(),"UTF-8");
    writer.write(requestBody);
    writer.flush();
    if (urlconnection.getResponseCode() == 200) 
     {                  
            InputStream input = urlconnection.getInputStream();
            //parse the response
     }

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