android - 打开通知面板时通知声音停止

Question

我正在处理一个项目，我在通知中遇到了一个奇怪的问题。
基本上我想在通知中播放警报，为此我在通知生成器中添加声音，即uri。
这是我的代码:

builder.setSmallIcon(R.mipmap.app_icon).setContentTitle(title)
            .setContentText(msg)
            .setColor(getResources().getColor(R.color.white))
            .addAction(R.drawable.alarm_off, getString(R.string.dismiss), pendingIntent)
            .setOngoing(true)
            .setSound(Uri.parse(path));

    Notification notification = builder.build();
    notification.flags |= Notification.FLAG_INSISTENT;


    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(WAKE_UP_ALARM_ID, notification);

通知出现在面板中，但是当我触摸通知面板向下滚动时，音乐会自动停止。
我无法理解这种情况。

请帮我解决问题。

谢谢

The flags that are used in notification builder

1.Notification.DEFAULT_SOUND:used to play sound.

2.Notification.FLAG_INSISTENT:this flag is makes your sound to ring continuously until you have done few operations on notification ie, either you drag the bar or you click the bar.

3.Notification.FLAG_AUTO_CANCEL:this flag is used to automatically cancel the notification after you have seen it
