使用AsyncTask在日志cat中打印数据<>出错

我正在尝试打印从 RiotApi 使用API ASyncTask 然后用 Log.d 数据和 Log.i 如果A RiotApiException 异常由引发 printSummonerData() 方法。但是,当我运行应用程序时,它编译并运行得很好,我没有得到 RiotApiExceptions 但数据不会被记录下来。有人能帮我弄明白为什么会这样吗?

附言:我不确定是否应该使用 异步任务 首先(我对线程、同步和异步任务等完全陌生),但是根据我在Android文档中读到的内容,我不应该用网络请求等来阻塞主UI线程,所以我认为我应该使用 异步任务 . 如果我的假设是错误的,请纠正我。

 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());
    }
}
