本文详细介绍了如何使用Android系统服务创建Notification实例的过程，并强调了PendingIntent在处理Notification点击事件时的唯一性要求，避免事件被覆盖的问题。

nm = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
		Notification notification = new Notification(android.R.drawable.stat_sys_download, itemname, System
				.currentTimeMillis());
		Intent notificationIntent = new Intent(context, InstallActivity.class);
		notificationIntent.putExtra("hasdownloaded", false);
		notificationIntent.putExtra("oranotificationid", oranotificationid);		
		PendingIntent contentIntent = PendingIntent.getActivity(context,
				this.oranotificationid,
				notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);
//		notification.contentIntent = contentIntent;

		notification.setLatestEventInfo(context, null, null,
				contentIntent);
		notification.contentView = new RemoteViews(context.getPackageName(),
				R.layout.imediadotbiz_process);
		notification.contentView.setTextViewText(R.id.dotbizimedia_core_tv_downing, itemname);
		notification.contentView.setProgressBar(R.id.dotbizimedia_core_pb_downing, 100, 0, false);
               nm.notify(oranotificationid, notification);

启动多个notification后，设置每个notification对应的事件，注意“

PendingIntent contentIntent = PendingIntent.getActivity(context,
				this.oranotificationid,
				notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);

第二个参数必须唯一，否则notification点击事件会被后边的notification覆盖，以致只有最后产生的notification有点击事件

notification机制有空得好好研究下，待续
