Android not showing all notifications

I made an app that can send a lot notifications at the same time, the problem is if the number of notifications is bigger than like 6 or seven not all notifications show up, despite the log saying that all notifications were created and having unique ids.

here is the code of the service for the notifications

class GeofenceService : JobIntentService() {

    override fun onHandleWork(intent: Intent) {

        if (intent.action == GeofencingConstants.ACTION_GEOFENCE_EVENT) {
            val geofencingEvent = GeofencingEvent.fromIntent(intent)

            if (geofencingEvent.hasError()) {
                val errorMessage = errorMessage(this, geofencingEvent.errorCode)
                Log.e(TAG, errorMessage)
                return
            }

            if (geofencingEvent.geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER) {
                Log.v(TAG, this.getString(com.superapps.ricardo.smithnotes.R.string.geofence_entered))

                val fenceId = when {
                    geofencingEvent.triggeringGeofences.isNotEmpty() ->
                        geofencingEvent.triggeringGeofences
                    else -> {
                        Log.e(TAG, "No Geofence Trigger Found! Abort mission!")
                        return
                    }
                }

                val notificationManager = ContextCompat.getSystemService(this, NotificationManager::class.java) as NotificationManager
                notificationManager.handleNotification(this, fenceId)
            }
        }
    }

    companion object {
        private const val TAG = "geofence-transitions"
        private const val JOB_ID = 573

        fun enqueueWork(context: Context, intent: Intent?) {
            enqueueWork(context, GeofenceService::class.java, JOB_ID, intent!!)
        }
    }

here the code for the notification generation

fun NotificationManager.handleNotification(context: Context, geofences: List<Geofence>){
    val list = ArrayList<Notification>()
    val set = mutableSetOf<Int>()
    val notificationIdBase = (Date().time / 1000L % Int.MAX_VALUE).toInt()
    this.apply {
        for (i in geofences.indices){
            val notificationId = notificationIdBase + i
            val notification = createGroupNotification(context, notificationId, geofences[i].requestId)
            list.add(notification)
            notify(notificationId, notification)
            set.add(notificationId)
            Log.d("TAG", notificationId.toString())
        }

        Log.d("TAG", geofences.size.toString() + " " + list.size + " " + set.size)
        for (id in set){
            Log.d("TAG", id.toString())
        }
    }
}

and here the logs for a case with 29 notifications generated but only 24 showed up on the phone.

I even tried grouping them in a notification group but even more notifications disappear.

Thanks

use this code Support all Versions

     lateinit var notification: NotificationCompat.Builder
        lateinit var manager: NotificationManager
        val channel = "NotificationTest"
        lateinit var notificationChannel: NotificationChannel


         manager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                notificationChannel = NotificationChannel(channel, 
             "notification",NotificationManager.IMPORTANCE_DEFAULT)
                manager.createNotificationChannel(notificationChannel)
            }

            notification=NotificationCompat.Builder(this,channel)
                    .setContentTitle("Title")
                    .setContentText("this is for test")
                    .setAutoCancel(true)
                    .setSmallIcon(R.mipmap.ic_launcher)


    manager.notify(1,notification.build())

If you are working on the android versions above oreo, then you have to use a notification channel for notifications from the notificationManager. I think it will work, as it did in mine.

As mentioned by Tenfoure04 in comments, there's a hard limit on notificationns per package(https://github.com/aosp-mirror/platform_frameworks_base/blob/439ac26e6792b38deff4166dc7c1b35ddce18804/services/core/java/com/android/server/notification/NotificationManagerService.java#L291).

Another problem that you might be facing is bundling of notifications by android. Similar notifications might be getting bundled. Just try to decrease the frequency of notifications.
