Question

SetSound - 此 API 现在已过时。用什么？
我可以用.SetDefaults (Resource.Drawable.MYSOUNDMP3)在

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
        .SetContentTitle ("Sample Notification")
        .SetContentText ("Hello World! This is my first notification!")
        .SetDefaults (NotificationDefaults.Sound)
        .SetSmallIcon (Resource.Drawable.ic_notification);

我就是这样做的，一切正常。

我创建 channel

            if (Build.VERSION.SdkInt < BuildVersionCodes.O)
            {
                // Notification channels are new in API 26 (and not a part of the
                // support library). There is no need to create a notification
                // channel on older versions of Android.
                return;
            }
            string name = "MyName";
            var description = "Notice";
            var channel = new NotificationChannel(CHANNEL_ID, name, NotificationImportance.High)
            {
                Description = description
            };
            var soundUri = Android.Net.Uri.Parse($"{ContentResolver.SchemeAndroidResource}://{Application.Context.PackageName}/{Resource.Drawable.mysound}");
            var audioAttributes = new AudioAttributes.Builder()
            .SetContentType(AudioContentType.Sonification)
                .SetUsage(AudioUsageKind.Notification)
                .Build();

            channel.SetSound(soundUri, audioAttributes);

            var notificationManager = (NotificationManager)GetSystemService(NotificationService);
    notificationManager.CreateNotificationChannel(channel);

我创建通知

var builder = new NotificationCompat.Builder(this, CHANNEL_ID)
            .SetContentTitle(SetContentTitle)
            .SetContentText(SetContentText)
            .SetChannelId(CHANNEL_ID)
            .SetSmallIcon(Resource.Drawable.icon);

            // Finally, publish the notification:
            var notificationManager = NotificationManagerCompat.From(this);

            // Publish the notification:
            int notificationId = 1;
            notificationManager.Notify(notificationId, builder.Build());

将 AudioUsageKind.Alarm 更改为 AudioUsageKind.Notification

SetSound从 API 级别 26 开始，Android 端已弃用。您可以在 official Android API documentation 中阅读有关它的更多信息。

如文档所示，您可以使用 NotificationChannel 的 SetSound反而。
您可以在 Xamarin 中找到如何使用 NotificationChannels 的示例 here
