我的通知代码(位于扩展服务的类中)：

Context context = getApplicationContext();

    CharSequence contentTitle = "Notification";

    CharSequence contentText = "New Notification";

    final Notification notifyDetails =
        new Notification(R.drawable.icon,"Consider yourself notified",System.currentTimeMillis());

    Intent notifyIntent = new Intent(context,MainActivity.class);

    PendingIntent intent =
          PendingIntent.getActivity(context,notifyIntent,PendingIntent.FLAG_UPDATE_CURRENT | Notification.FLAG_AUTO_CANCEL);

    notifyDetails.setLatestEventInfo(context,contentTitle,contentText,intent);

    ((NotificationManager)getSystemService(NOTIFICATION_SERVICE)).notify(NOTIFICATION_ID,notifyDetails);

如果在创建服务的应用程序打开时单击通知,通知将消失(由于FLAG_AUTO_CANCEL),但活动未切换.

如果我从主屏幕点击通知,通知将消失,我的应用程序将被带到前面,但它仍然保留在进入主屏幕之前打开的活动,而不是进入主屏幕.

我究竟做错了什么？如何指定将被提取的活动？
