最近開發中模組功能，使用NotificationManager觸發多個Notification:

private void showIMNotification(Context context, String ticker,
			Bitmap defaultBitmap, UnreadEntity unreadEntity, int notificationId) {
		Intent intent = new Intent(CHATATION_FLAG);
		intent.putExtra("chat_session_key", unreadEntity.getSessionKey());
		NotificationManager manager = (NotificationManager) context
				.getSystemService(Context.NOTIFICATION_SERVICE);
		PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
				intent, PendingIntent.FLAG_UPDATE_CURRENT);
		Notification notify1 = new Notification();
		notify1.icon = R.drawable.logo;
		notify1.when = System.currentTimeMillis();
		String appName = "";
		try {
			ApplicationInfo appInfo = context.getPackageManager()
					.getApplicationInfo(
							PhoneTools.getPackageInfo(context).packageName,
							PackageManager.GET_META_DATA);
			appName = appInfo.metaData.getString("MY_APP_LABEL");
		} catch (NameNotFoundException e) {
			e.printStackTrace();
			appName = context.getString(R.string.app_name);
		}
		notify1.tickerText = ticker;
		notify1.setLatestEventInfo(context, appName, ticker, pendingIntent);
		notify1.number = 1;
		notify1.flags |= Notification.FLAG_AUTO_CANCEL; 
		manager.notify(notificationId, notify1);
	}
 

最後修改為：

PendingIntent pendingIntent = PendingIntent.getActivity(context, StringUtil.getIntUUID(),
				intent, PendingIntent.FLAG_UPDATE_CURRENT);
