不同的通知声音在Oreo中不起作用 [英] Different notification sound not working in Oreo

问题描述

我仅在 Oreo 版本中遇到一些与通知相关的问题.我遵循此链接，并按照他的建议在卸载/安装应用程序后成功获得了自定义声音.

I am facing some Notification related issue in Oreo Version only. I follow this link and successfully got custom sound after uninstall/install the app as he has suggested.

现在的问题是我想在我的应用程序中使用两种自定义声音，为此，我有如下代码:

Now problem is that I want to use two custom sound in my app, For that, I have code like:

private void sendNotification(NotificationBean notificationBean) {
    String textTitle = notificationBean.getTitle();
    String alert = notificationBean.getMessage().getAlert();
    int orderId = notificationBean.getMessage().getOrderId();
    String notificationType = notificationBean.getMessage().getNotificationType();
    String sound = notificationBean.getMessage().getSound();

    Intent intent = new Intent(this, NavigationDrawerActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    Uri soundUri;

    if (notificationType.equals("Pending"))
        soundUri = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.sound);
    else
        soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, getString(R.string.app_name))
            .setSmallIcon(R.drawable.ic_stat_name)
            .setContentTitle(textTitle)
            .setContentText(alert)
            .setSound(soundUri)
            .setContentIntent(pendingIntent)
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);

    // Create the NotificationChannel, but only on API 26+ because
    // the NotificationChannel class is new and not in the support library
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        CharSequence name = getString(R.string.app_name);
        String description = getString(R.string.app_name);
        int importance = NotificationManager.IMPORTANCE_DEFAULT;

        NotificationChannel channel = new NotificationChannel(getString(R.string.app_name), name, importance);
        channel.setDescription(description);

        AudioAttributes attributes = new AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                .build();

        channel.enableLights(true);
        channel.enableVibration(true);
        channel.setSound(soundUri, attributes);

        // Register the channel with the system; you can't change the importance
        // or other notification behaviors after this
        NotificationManager notificationManager = getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
    }

    NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);

    // notificationId is a unique int for each notification that you must define
    notificationManager.notify(101, mBuilder.build());
}

如果我收到notificationType = "Pending"，那么我想使用自定义声音，否则我要使用DEFAULT声音，但是这里正在播放的是第一次播放的声音(当我第一次收到通知时.).

If I get notificationType = "Pending" then I want to use custom sound, otherwise DEFAULT sound but Here It is playing that sound which is played first-time (When I receive notification first time.).

我仅在OREO中遇到此问题.在所有其他设备上，它的工作正常.

I am getting this problem in OREO only. In all other devices its working fine.

推荐答案

问题:
似乎是通知频道问题.

Problem:
It seems Notification Channel issue.

解决方案:
您应该创建单独的频道，或者删除自己的频道.

Solution:
Either you should create separate channel, or you should delete your own channel.

策略:
1)创建单独的频道:
如果您要保留应用的 多个渠道 以及 各种 配置，则可以选择此策略.
要创建单独的频道，只需在创建频道时提供唯一的频道ID.
即:

Strategy:
1) Create separate channel:
You may select this strategy if you want to persist multiple channels along with various configuration for your app.
To create separate channel, just provide unique channel ID while creating it.
i.e.:

NotificationChannel channel = new NotificationChannel(uniqueChannelId, name, importance);

2)删除您现有的频道并重新创建:
如果您只想保留 仅一个渠道 以及应用的 更新 配置，则可以选择此策略.

2) Delete your existing channel and re-create it:
You may select this strategy if you want to persist only one channel along with updated configuration for your app.

要删除自己的频道并重新创建频道，请执行以下操作:

To delete your own channel and re-create it, following may work fine:

NotificationManager mNotificationManager = getSystemService(NotificationManager.class);

NotificationChannel existingChannel = notificationManager.getNotificationChannel(channelId);

//it will delete existing channel if it exists
if (existingChannel != null) {
mNotificationManager.deleteNotificationChannel(notificationChannel);
}
//then your code to create channel
NotificationChannel channel = new NotificationChannel(channelId, name, importance);
