I use Onesignal to push notification and need to cancel all notification of onPause and onResume,
NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
if (notificationManager!=null)
notificationManager.cancelAll();
but it's not work correctly. When app restarted I get all old notifications. I restard my app and these old notifications need to not showing.
Please help to fix this!!
You need to use this method from OneSignal SDK clearOneSignalNotifications
or for only one notifcation cancelNotification.

the following code works for me when the notification received while the application run on the foreground.
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(notificationID);
but when the notification received while the application on the background then it does not work (the specific notification that I try to delete is not deleted).
cancelAll() functtion delete all background and foreground received notifications but I don't want to use it because I want to delete a specific notification.
I am getting notification via FCM(Firebase cloud messaging).
Android 10
thank you
Use
notificationmanger.cancelall();
That will close tour all notifications from any where so you can create them again i hope its helpful
Public Int Helpnotification = 6:
Notificationmanger.notify(notification , Helpnotification);
I'm doing in-app notifications on Android.
I'm using NotificationCompat.Builder and NotificationManager to do it.
I set my notifications priority to PRIORITY_HIGH to display them as a popup.
But the notification is displayed in the Android notifications history. How to prevent this ?
To cancel a notification you call
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(NOTIFICATION_ID);
I would suggest calling this code after you create the pop up so that there is no notification left in the tray. I found this code here: How to clear a notification in Android
I have a strange issue. I have two way to send notifications in my Android app; one from the Android service and the other through FCM.
The scenarios are as follows:
Regardless of whether the app is running or not, the icon of the notification sent from the Android service appears correctly.
When the app is running, the notification icon appears still appears correctly if I send the notification via FCM.
But if the app isn't running and I send the notification via FCM, a white square is displayed instead of the notification icon.
My code in FCMService:
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Android App")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
Most likely your problem is the difference between notification-messages and data-messages.
Please read: https://firebase.google.com/docs/cloud-messaging/concept-options#notifications_and_data_messages
Use notification messages when you want FCM to handle displaying a
notification on your client app's behalf. Use data messages when you
want to process the messages on your client app.
Currently the FCM Web Console only sends notification-messages
So all the messages sent via Web Console (or via API with a notification payload) will be have in this way:
if the app is closed or in background: FCM will display the notification. if you want to customize it you can, but you need to provide specific configuration (in the manifest or in the send API call) see https://firebase.google.com/docs/cloud-messaging/android/client#manifest
if the app is in foreground: FCM will call onMessageReceived()
.
If the behavior that you want is that onMessageReceived() is always called:
then you need to use a data-only (no notification) message
This is a FMC bug detailed in github fcm page.

Hi i've used parse push notification in my android app.
i'm not using noraml notification. i've register parse push notification. The notification alert comes from server
device received the push notification successfully.
for example i've received 10 notification from server, if i open one notification on my device, the app has opened and the one notification has deleted.
My question is,
how to clear the other 9 push notification alert on status bar when open one notification..?
Does android.app.NotificationManager.cancelAll() not work?
If you need to do something very custom, you can use ParsePush to launch an Intent rather than creating a Notification. You can then use a BroadcastReceiver to create Notifications with non-standard behavior (i.e. selective stacking, dismiss all when one is interacted with, etc).
Use this in your launch activity:
String ns = getActivity().NOTIFICATION_SERVICE;
NotificationManager nMgr = (NotificationManager) getActivity().getSystemService(ns);
nMgr.cancelAll();
Use this in your Main Activity
NotificationManager nm = (NotificationManager) get SystemService(Context.NOTIFICATION_SERVICE);
nm.cancelAll;
How can I make a persistent notification, that will update every time the users sees it?
form the service
To show the notification when the Service is running, you call:
startForeground(R.string.notification_id, myNotification);
giving the method an ID for your service, and a Notification that you have created.
At any point, your Service can update what the user sees by using the same R.string.notification_id and posting a new Notification:
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(R.string.notification_id, myNotification);
For creating a Notification, you need to read up on Notification.Builder (android docs here).
There is also a good answer on a related question: How exactly to use Notification.Builder? Apologies for not reposting his answer, but it includes a lot of code and will sort you out.
