Question

我通过GCM服务向Android设备发送通知。向客户端发送消息不是问题，因为在手机上收到通知时没有播放声音这是一个问题。

我在客户端使用以下代码（mono android）来建立通知请求

void createNotification(string title, string desc)
     {
       //Create notification
       var notificationManager = GetSystemService(Context.NotificationService) as NotificationManager;

    //Create an intent to show ui
    var uiIntent = new Intent(this, typeof(Main));

    //Create the notification
    var notification = new Notification(Android.Resource.Drawable.SymActionEmail, title);

    //Auto cancel will remove the notification once the user touches it
    notification.Flags = NotificationFlags.AutoCancel;

    //Set the notification info
    //we use the pending intent, passing our ui intent over which will get called
    //when the notification is tapped.
    notification.SetLatestEventInfo(this, title, desc, PendingIntent.GetActivity(this, 0, uiIntent, 0));

    //Show the notification
    notificationManager.Notify(1, notification);
}

在这里我可以放置通知声音的详细信息吗？我已经尝试了Notification.Sound成员，但它要求提供一个我没有引用的uri。

Answer 1

如果要播放自定义通知声音，请添加此项

  notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3");

Answer 2

在功能激活的默认通知声音中添加此行代码。

notification.Defaults = NotificationDefaults.Sound;

使用GCM服务通过Android设备无通知
