android - 如何在通知进入android时获取Bundle数据

Question

我需要打开特定的 fragment ，当我的 android 应用程序收到通知时，当应用程序被杀死或关闭时，当通知到来并单击通知时，我需要打开 fragment 并调用 api这是我的代码。当我的应用程序当时处于运行状态时，通知来了但不显示在通知栏上

  Bundle bundle = getIntent().getExtras();
    if (bundle != null) {

        String value = bundle.getString("api_url");

        Toast.makeText(this, value, Toast.LENGTH_SHORT).show();
    }
