当我尝试从Android中的Facebook中提取数据时，获取NetworkOnMainThreadException

Question

我正在编写的应用程序需要来自Facebook的用户数据。当我可以从Facebook检索照片的问题时，我正在使用GraphRequest。我通过找到如何使用URL和HttpURLConnection提取位图来解决它。然后，当我提出要求时，出现错误NetworkOnMainThreadException。

我想从Facebook提取数据到我的应用程序UI。我要求使用Graph请求方法提供信息。我收到数据，直到需要来自Facebook的位图为止。我找到了使用HttpURLConnection的解决方案，但出现了NetworkOnMainThreadException。我查找了多个解决方案，说我需要执行ASYNC任务。我以为graphrequest是ASYNC任务，所以我不知道下一步该怎么做。

protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.front_page);
    android.support.v7.widget.Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    drawer = findViewById(R.id.drawer_front_page);
    NavigationView nV = findViewById(R.id.drawer_view);
    View header = nV.getHeaderView(0);
    nV.setNavigationItemSelectedListener(this);
    callbackManager = CallbackManager.Factory.create();
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar,
            R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();
    getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
            new VenueList()).commit();
    nV.setCheckedItem(R.id.list_venue);

    ImageView drawerProfilePicture = header.findViewById(R.id.drawer_pic_profile);
    TextView drawerUserName = header.findViewById(R.id.drawer_profile_username);
    TextView drawerUserEmail = header.findViewById(R.id.drawer_profile_email);

    drawerUserName.setText("Hello My Baby");
    drawerUserEmail.setText("myemail@gmail.com");

    if (AccessToken.getCurrentAccessToken() != null && !AccessToken.getCurrentAccessToken().isExpired()) {
        GraphRequest request = GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(), (object, response) -> {
            try {

                userFullName = object.getString("name");
              //  userFullName = object.getString("first_name") + " " + object.getString("last_name");
                //userEmail = object.getString("email");
                drawerUserName.setText(userFullName);
                //drawerUserEmail.setText(userEmail);
                String id = object.getString("id");


              /*  URL imageURL = new URL("https://graph.facebook.com/" + id + "/picture?type=large");

                Bitmap bitmap = BitmapFactory.decodeStream(imageURL.openConnection().getInputStream());*/

                URL url = new URL("https://graph.facebook.com/" + id + "/picture?type=large");
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.setDoInput(true);
                connection.connect();
                InputStream input = connection.getInputStream();
                Bitmap myBitmap = BitmapFactory.decodeStream(input);

                drawerProfilePicture.setImageBitmap(myBitmap);

               /* userProfilePicURL = "https://graph.facebook.com/" + id + "/pictures?type=normal";

                Glide.with(FrontPageClass.this).load(userProfilePicURL).into(drawerProfilePicture);*/

                Log.i(TAG, "name from Success: " + userFullName);
                Log.i(TAG, "email from Sucess: " + userEmail);

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

        });
        Bundle parameters = new Bundle();
        request.setParameters(parameters);
        request.executeAsync();

    }


    Log.i(TAG, "onCreate: " + userFullName);
}

我想对从我写入的URL中获得的位图进行dsiplay。我得到了NetworkOnMainThreadException，但我不明智地假设GraphRequest是一个异步进程。我不知道下一步该怎么修复代码。
