如何在Android中更新和删除待处理的意图和通知

Question

whenever i attempt to update the notification or Intent a new one is created instead which i don't want. I think the problem is that the Intents are not being identified whenever i'm trying to update it. The link to the code is below:

1. To update a PendingIntent , you should use the same REQUEST_CODE that you used before to create it.

    PendingIntent pIntent = PendingIntent.getBroadcast(context, REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

2. To cancel/delete an existing PendingIntent , you can use PendingIntent.cancel() method.

    PendingIntent.getBroadcast(context, REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT).cancel(); 

3. To update a Notification , you can use NotificationManager.notify() method with the NOTIFICATION_ID that you want to update.

    NotificationManager notificationManager= (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(NOTIFICATION_ID, notification); 

   Notification id should be unique within your application. If a notification with the same id has already been posted by your application and has not yet been canceled, it will be replaced by the updated information.

4. To cancel/remove an existing Notification , use NotificationManager.Cancel() method with the NOTIFICATION_ID that you want to cancel.

    notificationManager.cancel(NOTIFICATION_ID); 

Hope this will help~
