这个我原本的代码，想要解决这个问题，只需要给notification添加一个事件setLatestEventInfo。

NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notify = new Notification();
notify.icon = R.drawable.ic_launcher;
notify.tickerText = "点击下载最新App";
notify.when = System.currentTimeMillis();
notify.defaults = Notification.DEFAULT_LIGHTS;
notify.flags = Notification.FLAG_AUTO_CANCEL;

nm.notify(notificationId, notify);

instance.put("activeUpdateShouldShow", false);

解决方案如下：

Intent intent = new Intent(ctx, UpdateService.class);
intent.putExtra("apkUrl", apkurl);
PendingIntent pendIntent = PendingIntent.getService(ctx, 0, intent, 0);

notify.setLatestEventInfo(ctx, "AAAAA", "BBBBBBB", pendIntent);

但是setLatestEventInfo方法是一个过时的方法，至于用什么方式替代还有待研究
