使用 AppCenter 成功发送推送通知但收到通知时没有声音（xamarin android）

Question

我在 xamarin android 项目中使用 AppCenter 推送通知。通知成功收到，但没有声音。请指导我如何处理通知声音。

protected override void OnStart()
    {
        AppCenter.Start("c71c0b73-a242-469e-ad97-990ca0853f9b", typeof(Push));
        CustomProperties properties = new CustomProperties();
        properties.Set("Sound", true);
        AppCenter.SetCustomProperties(properties);
    }

为通知添加声音，您可以使用 NotificationChannel.SetSound()，将 mp3 文件添加到您的 Android 项目的 Resources/raw/soundFile.mp3 下，并将构建设置为 Android Resource )

private void createNotificationChannel()
    {          
            var channelName = GetString(Resource.String.noti_chan_urgent);
            var channelDescription = GetString(Resource.String.noti_chan_urgent_description);

            // set the vibration patterm for the channel
            long[] vibrationPattern = { 100, 200, 300, 400, 500, 400, 300, 200, 400 };

            // Creating an Audio Attribute
            var alarmAttributes = new AudioAttributes.Builder()
                .SetContentType(AudioContentType.Sonification)
                .SetUsage(AudioUsageKind.Notification).Build();

                // Create the uri for the alarm file                 
            Android.Net.Uri alarmUri = Android.Net.Uri.Parse(${ContentResolver.SchemeAndroidResource}://{Context.PackageName}/{Resource.Raw.soundFile}");


            // create chan1  which is the urgent notifications channel
            var chan1 = new NotificationChannel(PRIMARY_CHANNEL_ID, channelName, NotificationImportance.High)
            {
                Description = channelDescription
            };


            // set the channel properties
            chan1.EnableLights(true);
            chan1.LightColor = Color.Red;
            chan1.SetSound(alarmUri, alarmAttributes);
            chan1.EnableVibration(true);
            chan1.SetVibrationPattern(vibrationPattern);               
            chan1.SetBypassDnd(true);
            chan1.LockscreenVisibility = NotificationVisibility.Public;

            // finally create the notification channel
            var manager = (NotificationManager)GetSystemService(NotificationService);
            manager.CreateNotificationChannel(chan1);
    }
