Xamarin Android Local Notification

Question

我在项目中使用 API 级别 10（Xamarin.Android v2.3 支持）

程序集引用缺失错误。

主要活动

按钮单击处理程序具有以下代码

        Bundle valuesForActivity = new Bundle();
        valuesForActivity.PutInt("count", _count);
        // Create the PendingIntent with the back stack
        // When the user clicks the notification, SecondActivity will start up.
        Intent resultIntent = new Intent(this, typeof(SecondActivity));
        resultIntent.PutExtras(valuesForActivity); // Pass some values to SecondActivity.
        TaskStackBuilder stackBuilder = TaskStackBuilder.Create(this);
        stackBuilder.AddParentStack(Java.Lang.Class.FromType(typeof(SecondActivity)));
        stackBuilder.AddNextIntent(resultIntent);
        PendingIntent resultPendingIntent = stackBuilder.GetPendingIntent(0, (int)PendingIntentFlags.UpdateCurrent);
        // Build the notification          
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .SetAutoCancel(true) // dismiss the notification from the notification area when the user clicks on it
            .SetContentIntent(resultPendingIntent) // start up this activity when the user clicks the intent.
            .SetContentTitle("Button Clicked") // Set the title
            .SetNumber(_count) // Display the count in the Content Info
            .SetSmallIcon(Resource.Drawable.monoandroidsplash) // This is the icon to display
            .SetContentText(String.Format("The button has been clicked {0} times.", _count)); // the message to display.
        // Finally publish the notification
        NotificationManager notificationManager = (NotificationManager)GetSystemService(NotificationService);
        notificationManager.Notify(ButtonClickNotificationId, builder.Build());
        _count++;`

获取错误

TaskStackBuilder stackBuilder = TaskStackBuilder.Create(this);

和

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)

错误是缺少程序集引用TaskStackBuilder不存在

我没有得到程序集参考中缺少的内容请帮忙

这是一个迟到的回复，但可能会帮助其他人。

您提到的问题是由于Mono.Anroid的版本（较低版本）而发生的

在较低版本（如 4.2）中，缺少 Android.App.TaskstackBuilder 命名空间。升级Mono.Android可能会解决这个问题。
