Question

我有一个应用程序，在其中我更新了通知声音（添加了自定义声音）。现在的问题是，当我收到一条通知时，我听到双声，第一声是我早些，第二声是我添加了新声。经过搜索和谷歌搜索，我知道我们需要卸载并重新安装该应用程序才能使“新”声音正常工作。显而易见，我不能要求2k +用户重新安装该应用程序。那么有办法解决吗？我猜notificationmanager存储了一些临时数据来处理/播放通知（我想我不知道）。

这是我的代码

    public void sendNotification(String string, Context context) {

        //    NotificationManager notificationManager2 = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
        notificationManager.cancel(notificationId);


        if (soundUri == null) {
            soundUri = Uri.parse("android.resource://" + context.getPackageName() + "/" + R.raw.mycustomsound);
        }
//        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        String channelId = "channel-01";
        String channelName = "Channel Name";
        int importance = NotificationManager.IMPORTANCE_HIGH;
        Intent intent = new Intent(context, MainFrag.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            NotificationChannel mChannel = new NotificationChannel(
                    channelId, channelName, importance);
            AudioAttributes attributes = new AudioAttributes.Builder()
                   .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();
            mChannel.setSound(soundUri, attributes);
            notificationManager.createNotificationChannel(mChannel);

            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, channelId)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle("My Title")
                    .setContentText("Hello there!")
                    .setContentIntent(pendingIntent)
                    .setAutoCancel(true)
                    .setDefaults(0)
                    .setGroupAlertBehavior(GROUP_ALERT_SUMMARY);

            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

            stackBuilder.addNextIntent(intent);

            mBuilder.setContentIntent(pendingIntent);

            notificationManager.notify(notificationId, mBuilder.build());

        } else {

            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, channelId)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle("Title")
                    .setContentText("Hello there!")
                    .setContentIntent(pendingIntent)
                    .setAutoCancel(true)
                    .setDefaults(0)
                    .setGroupAlertBehavior(GROUP_ALERT_SUMMARY);
//                .setSound(defaultSoundUri);
                    .setSound(Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
                            + "://" + context.getPackageName() + "/raw/mycustomsound"));

            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

            stackBuilder.addNextIntent(intent);

            mBuilder.setContentIntent(pendingIntent);

            notificationManager.notify(notificationId, mBuilder.build());
        }
    }

而且，有时我还会收到鬼通知（队列中播放了4-5次声音！所以我的代码中一定会有毛刺。
