android - Facebook 好友邀请请求不显示消息

Question

我有一个String message = "hi";，当用户收到邀请时，他看不到我的消息，但是类似you have a request from ...

params.putString("message", message);
params.putString("to", "123123123");
WebDialog webdialog = new WebDialog.Builder(PurchaseFlowActivity.this,
        Session.getActiveSession(), action, params)
        .setOnCompleteListener(new WebDialog.OnCompleteListener() {
            @Override
            public void onComplete(Bundle values,
                    FacebookException error) {

            }
        }).build();
Window dialog_window = progressDialog.getWindow();
dialog_window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);
webdialog.show();

Answer 1

该消息未显示在邀请的通知弹出窗口中。

仅当目标用户已安装该应用程序时才会显示。
