Printing data in the Logcat using ASyncTask<> gone wrong

Issue

I'm trying to print some data that i get from the RiotApi Api using ASyncTask and then log them in the logcat using Log.d for the data and Log.i if a RiotApiException exception is thrown by the printSummonerData() method. However, when i run the app it compiles and runs just fine and i get no RiotApiExceptions but the data doesn't get logged. Can anybody help me figure out why this is happening?

PS: I'm not sure if i should be using ASyncTask in the first place (i'm completely new to threads,Synchronous and Asynchronous Tasks etc) but from what i've read in the Android Documentation i shouldn't block the main UI thread with Network Requests etc. so i thought i should use ASyncTask. Please correct me if my assumption was wrong.

 public class MainActivity extends AppCompatActivity {

    private final static String API_KEY = "MYKEY";

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

        new DownloadSummonerData();
    }

    private static class DownloadSummonerData extends AsyncTask<Void, Void, Void> {
        protected Void doInBackground(Void... urls) {
            try {
                printSummonerData();
            } catch (RiotApiException e) {
                e.printStackTrace();
                Log.i("LOL","Something went wrong!");
            }
            return null;
        }

        protected void onProgressUpdate(Void... progress) {

        }

        protected void onPostExecute(Void result) {

        }
    }


    private static void printSummonerData() throws RiotApiException {
        ApiConfig config = new ApiConfig().setKey(API_KEY);
        RiotApi api = new RiotApi(config);
        Summoner summoner = api.getSummonerByName(Platform.EUNE, "XmaxUniverse");
        Log.d("LOL","Name: " + summoner.getName());
        Log.d("LOL","Summoner ID: " + summoner.getId());
        Log.d("LOL","Account ID: " + summoner.getAccountId());
        Log.d("LOL","PUUID: " + summoner.getPuuid());
        Log.d("LOL","Summoner Level: " + summoner.getSummonerLevel());
        Log.d("LOL","Profile Icon ID: " + summoner.getProfileIconId());
    }
}

Solution

You didn't start your AsyncTask. Do his

new DownloadSummonerData().execute();

OR

// Assume DownloadSummonerData extends AsyncTask
DownloadSummonerData myAsyncTask= new DownloadSummonerData();

// Execute in parallel
myAsyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR)
