如何通过单击通知中的按钮来关闭应用程序？

Question

我点击按钮后尝试关闭我的应用程序。

我知道我需要使用待定意图并且意图这样做，但我不知道我该怎么做以及我可以使用哪些标记或动作。

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "")
            .setSmallIcon(R.mipmap.ic_launcher_notification)
            .setContentTitle("Close your app")
            .setContentText("Your app is still running...")
            .addAction(R.drawable.ic_exit,"Close App",
                    PendingIntent.getBroadcast(this, 0, intent, 0))
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

    builder.setContentIntent(pendingIntent);

    NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(0, builder.build());

这不起作用......
