关于Facebook游戏请求如何在我的应用程序启动器时获取数据

Question

当我的应用启动器出现在Activity中时，如何获取数据（＆＃34; world＆＃34;）

GameRequestContent content = new GameRequestContent.Builder()
                     .setMessage("hello")
                     .setData("world")
                     .build();
             GameRequestDialog g = new GameRequestDialog(getActivity());
             g.registerCallback(callbackManager, new FacebookCallback<GameRequestDialog.Result>() {
                 @Override
                 public void onSuccess(GameRequestDialog.Result o) {
                     Log.i("onSuccess", new Gson().toJson(o.getRequestRecipients()));
                 }
                 @Override
                 public void onCancel() {
                     Log.i("onSuccess", "onCancel");
                 }
                 @Override
                 public void onError(FacebookException error) {
                     Log.i("onError", error.getMessage());
                     error.printStackTrace();
                 }
             });
             g.show(content);
