Not getting heads up notifications for a while when you swipe up local notifications

When I swipe up after the local notification comes, the application notifications don't appear on the screen for a while. What could be the reason for this? I've read something that when heads up notifications are swiped up, it sends a warning to the system to prevent heads up notifications for a certain period of time, but how can I prevent this? I don't have any problems getting notifications in my app other than that.

How to dismiss all desired notifications on Android?

I'm creating a chat app that sends and receives notifications through Firebase Cloud Functions. Let's suppose I have 2 friends, and each friend sends me 5 messages(5 notifications). When I open a chat in my chat list, I want all notifications for that chat to be dismissed and the others not.
Currently I can only dimiss 1 notification. If I get more than one notification the notificationManager.cancel(notificationId) doesn't work. I don't want to use notificationManager.cancelAll() as I just want to dismiss some notifications.
override fun onMessageReceived(remoteMessage: RemoteMessage) {
remoteMessage.notification.let { notification ->
val type = remoteMessage.data[NOTIFICATION_TYPE]
val notificationChannelId = getNotificationChannelId(type)
val soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val intent = Intent(this, HomeActivity::class.java)
val notificationIntent = setIntent(remoteMessage.data)
val stackBuilder: TaskStackBuilder = TaskStackBuilder.create(this)
stackBuilder.addParentStack(HomeActivity::class.java)
stackBuilder.addNextIntent(intent)
stackBuilder.addNextIntent(notificationIntent)
val pendingIntent: PendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT)
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notificationBuilder = NotificationCompat.Builder(this, notificationChannelId)
.setContentTitle(notification?.title ?: "")
.setContentText(notification?.body ?: "")
.setStyle(
NotificationCompat.BigTextStyle()
.bigText(notification?.body ?: "")
)
.setSmallIcon(R.drawable.ic_stat)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setSound(soundUri)
.setColor(ContextCompat.getColor(applicationContext, R.color.colorNotification))
.setVibrate(vibrationPattern)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
notify(remoteMessage.data, notificationManager, notificationBuilder)
}
}
private fun notify(
data: Map<String, String>,
notificationManager: NotificationManager,
notificationBuilder: NotificationCompat.Builder
) {
when (data[NOTIFICATION_TYPE]) {
CHAT_MSG -> {
if (data[NotificationUtils.CHAT_ID] != ChatActivity.currentChat) {
notificationManager.notify(
CHAT_MSG_NOTIFICATION_ID,
notificationBuilder.build()
)
}
}
FRIEND_REQUEST -> {
notificationManager.notify(
FRIEND_REQUEST_NOTIFICATION_ID,
notificationBuilder.build()
)
}
}
}
OnStart():
fun dismissNotifications(notificationId: Int) {
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.cancel(notificationId)
}

My thoughts is:
Save all notificationIds in map where:
key is userName/userId in message.
value is List of notificationId
When you need to clear all notifications you just ask you map and clear all that notificationIds for that userName/userId

Notification works in Activity but not in Service

I am trying to integrate Firebase Cloud Messages into my app. The code I used in the showNotification function is from the Android User Interface Samples. I tried it in the Activity and it worked but am not sure why it's not working in the service. The println is showing the function is getting called and values are coming as expected. Is there anything am missing from the function?
class MessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage) {
if (remoteMessage.data.isNotEmpty()) {
val message = Gson().fromJson(remoteMessage.data.toString(), Message.Res::class.java).payload!!
showNotification(message.title, message.body, message.count)
}
}
private fun showNotification(title: String?, body: String?, count: Int = 0) {
println("_print::showNotification(title:$title, body:$body, count:$count)")
val mainPendingIntent = PendingIntent.getActivity(
applicationContext, BuildConfig.REQUEST_CODE,
Intent(applicationContext, MainActivity::class.java),
PendingIntent.FLAG_UPDATE_CURRENT
)
val builder = NotificationCompat.Builder(applicationContext, "channel_email_1")
.setContentTitle(title)
.setContentText(body)
.setSmallIcon(R.mipmap.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(resources, R.mipmap.ic_launcher_round))
.setContentIntent(mainPendingIntent)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setColor(ContextCompat.getColor(applicationContext, R.color.primary))
.setSubText(if (count > 1) "You have $count pending notifications" else title)
.setCategory(Notification.CATEGORY_EMAIL)
.setPriority(1)
.setVisibility(NotificationCompat.VISIBILITY_PRIVATE)
NotificationManagerCompat.from(applicationContext)
.notify(BuildConfig.NOTIFICATION_ID, builder.build())
}
}

Instead of
val mainPendingIntent = PendingIntent.getActivity(
applicationContext, BuildConfig.REQUEST_CODE,
Intent(applicationContext, MainActivity::class.java),
PendingIntent.FLAG_UPDATE_CURRENT
)
NotificationManagerCompat.from(applicationContext)
.notify(BuildConfig.NOTIFICATION_ID, builder.build())
I use:
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// Since android Oreo notification channel is needed.
setupChannels(notificationManager, builder)
// Create pending intent, mention the Activity which needs to be triggered
// when user clicks on notification.
val notificationId = Random.nextInt()
navigateToScreen(builder, notificationId)
val notification = builder.build()
notificationManager.notify(notificationId, notification)
}
private fun setupChannels(notificationManager: NotificationManager,
builder: NotificationCompat.Builder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = "channel_email_1"
val channel = NotificationChannel(channelId, "title",
NotificationManager.IMPORTANCE_DEFAULT).apply {
description = "body"
// Add other settings.
lockscreenVisibility = Notification.VISIBILITY_PUBLIC
canShowBadge()
setShowBadge(true)
}
notificationManager.createNotificationChannel(channel)
builder.setChannelId(channelId)
}
}
private fun navigateToScreen(builder: NotificationCompat.Builder,
notificationId: Int) {
val intent = Intent(this, MainActivity::class.java)
val pendingIntent = PendingIntent.getActivity(this, notificationId, intent,
PendingIntent.FLAG_UPDATE_CURRENT)
builder.setContentIntent(pendingIntent)
}

How to collapse push notifications into one icon?

An application receives push notifications. They can be different (payment, order, chat), so I have to show them all, not replacing old with new. A problem is that in old emulators (API 19) all push notifications are shown separately.
In newer emulators they are groupped into one, but (if I'm not mistaken) after 3 received notifications.
Data sent from FCM:
{
"to": "<push token>",
"data": {
"title": "Application name",
"message": "See a message",
"screen": "Main screen",
...
}
}
MyFirebaseMessagingService:
override fun onMessageReceived(remoteMessage: RemoteMessage) {
super.onMessageReceived(remoteMessage)
val soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val textStyle = NotificationCompat.BigTextStyle()
val title: String
val body: String
if (remoteMessage.data.isNullOrEmpty()) {
title = remoteMessage.notification?.title ?: ""
body = remoteMessage.notification?.body ?: ""
} else {
title = remoteMessage.data["title"] ?: ""
body = remoteMessage.data["message"] ?: ""
}
val notificationBuilder = NotificationCompat.Builder(this,
getString(R.string.default_notification_channel_id))
.setContentTitle(title)
.setContentText(body)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setStyle(textStyle)
.setSound(soundUri)
.setSmallIcon(R.drawable.ic_notification_icon)

val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// Since android Oreo notification channel is needed.
setupChannels(notificationManager, notificationBuilder)
// Create pending intent, mention the Activity which needs to be triggered
// when user clicks on notification.
val notificationId = Random.nextInt()
navigateToScreen(notificationBuilder, notificationId, remoteMessage)
val notification = notificationBuilder.build()
notificationManager.notify(notificationId, notification)
}
private fun setupChannels(notificationManager: NotificationManager,
notificationBuilder: NotificationCompat.Builder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = getString(R.string.default_notification_channel_id)

How to display notification in Group using SetGroup() in Android?

I have tried using "0" notification id and as well as unique notification id.
Also used setGroup() like below. It still generates a new notification every time. I want to merge the notification body and set the title as common.
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
super.onMessageReceived(remoteMessage)
remoteMessage?.let {
sendNotification(it.data["alert"])
}
}
private fun sendNotification(messageBody: String?) {
val channelId = "${this.packageName}-${this.getString(R.string.app_name)}"
val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val builder = NotificationCompat.Builder(this, channelId).apply {
setDefaults(Notification.DEFAULT_ALL)
setSmallIcon(if (Build.VERSION.SDK_INT >= 21) R.mipmap.ic_launcher else R.mipmap.ic_launcher_round)
setContentTitle(getString(R.string.app_name))
setContentText(messageBody)
setDefaults(NotificationCompat.DEFAULT_SOUND or NotificationCompat.DEFAULT_VIBRATE or NotificationCompat.DEFAULT_LIGHTS)
setStyle(NotificationCompat.BigTextStyle().bigText(messageBody))
priority = NotificationCompat.PRIORITY_DEFAULT
setAutoCancel(true)
setSound(defaultSoundUri)
setGroup(getString(R.string.app_name))
setGroupSummary(true)
}
val manager = getSystemService(NOTIFICATION_SERVICE) as? NotificationManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(channelId, getString(R.string.default_channel_name), NotificationManager.IMPORTANCE_HIGH)
manager?.createNotificationChannel(channel)
}
val intent = Intent(this, DashboardFlowActivity::class.java)
intent.putExtra(DashboardFlowActivity.ISFROMNOTIFICATION, true)
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
val pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT)
builder.setContentIntent(pendingIntent)
//manager?.cancelAll()
manager?.notify(this.getString(R.string.app_name), getID(), builder.build())
}
}
private val c = AtomicInteger(0)
private fun getID(): Int {
return c.incrementAndGet()
}
Anything I am doing wrong here? Also, I have gone through this answer. setgroup() in notification not working
