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 need to remove push notifiactions from other apps on notification bar.
I used NotificationListenerService to handle push notifications and then I get push notifications in onNotificationPosted(), it has cancelNotification() to cancel push notification. But i need to have a trigger, when I clicked some button in some fragment notification should remove, is it possible to call cancelNotification() from other place?
val nMgr: NotificationManager = ctx.getSystemService(ns) as
NotificationManager nMgr.cancelAll()
it remove notifications, which you created by yourself, but not from other apps
I'm sending data payloads through FCM and handling them in the onMessageReceived() method of FirebaseMessagingService. The problem is, when the app is in the background, the push notifications seem to be popping up each time the device handles them. I'd like them to be silent similar to how Android delivers notification payloads.
How do I make sure the notifications do not create this popup effect? I'm on Android 9.
Here's how the notification is generated on the client:
var pendingIntent = PendingIntent.GetActivity(this, 0, intent, PendingIntentFlags.OneShot);
var notificationBuilder = new NotificationCompat.Builder(this, myChannelId)
.SetContentTitle(title)
.SetContentText(body)
.SetSmallIcon(Resource.Mipmap.ic_launcher)
.SetAutoCancel(true)
.SetContentIntent(pendingIntent);
and this is how it's notified:
if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
notificationBuilder.SetChannelId(myChannelId);
var notificationManager = NotificationManager.FromContext(this);
notificationManager.Notify(myId, notificationBuilder.Build());
Notifications will appear with a popup effect ('Heads Up') view like shown in the screenshot if you set the notification channel priority to IMPORTANCE_HIGH or above, so to stop that happening, you should ensure the channel priority is IMPORTANCE_DEFAULT or lower.
If you have other notifications that you do want to use the heads up view, then you should create a separate NotificationChannel for this notification. Note that notification channels appear as 'Categories' in the notification settings for your app, allowing the user to choose which kinds of notifications they want to see from you, and two notifications wanting a different priority is a good indicator that they should be in different categories
When app is killed / in background...
When only 'data' payload is passed in request, notification will be generated with popup, and handled by user in 'onMessageReceived'
When only 'notification' payload is passed in request, notification will be generated without popup, and handled by android OS
When both 'data' and 'notification' payload are passed in request, notification will be generated without popup, and handled by android OS and data will be available for handling in extras of the intent.
So, in our case (don't want to show notification as popup) pass both 'data' and 'notification' payloads in request params. (Here title and body will be shown, what is passed in notification payload)

Use android lifecyclehandler and check whether app is in foreground or background and don't show the notification if app is in foreground lifecyclerhandler
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.

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;
