Android 单击通知时清除所有堆栈

我在android应用程序上使用FCM显示通知。除一个问题外，一切正常

当用户单击通知时，我需要关闭应用程序的所有后台和前台活动，并打开通知中指定的意图

我怎么做

我正在使用这样的待定意图

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        final PendingIntent resultPendingIntent =
                PendingIntent.getActivity(
                        mContext,
                        0,
                        intent,
                        PendingIntent.FLAG_CANCEL_CURRENT
                );

可以使用2个标志清除所有堆栈

  intentToLaunch.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
        intentToLaunch.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

  intentToLaunch.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
        intentToLaunch.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

试试这个

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);
