Android 13: User can dismiss notification even after setting "setOnGoing(true)"

Question

I am making a foreground service and as we know that such services need a notification to keep running. However since Android 13, the user can dismiss it just by swiping, thus the app is killed.

I tried to use setOnGoing(true) on the notification builder but no use.

I need to make the notification non-dismissable.

This is my code in Kotlin .

      private fun startForegroundServiceWithNotification() {
        Log.d("myTag", "startForegroundServiceWithNotification")
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val channelId = CHANNEL_ID
            val channelName = "Wish2Go step counter"
            val chan = NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH)
            val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            service.createNotificationChannel(chan)
        }


        var builder = NotificationCompat.Builder(this, CHANNEL_ID)
            .setOngoing(true)
            .setContentTitle("Counting steps")
            .setPriority(NotificationCompat.PRIORITY_HIGH)

        var notification = builder.build()
        notification.flags = Notification.FLAG_ONGOING_EVENT
        startForeground(1001, notification)

    }

Answer 1

I found the issue i had, apparently that i forgot to set the smallIcon for my notification

private fun startForegroundServiceWithNotification() {
    Log.d("myTag", "startForegroundServiceWithNotification")
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val channelId = CHANNEL_ID
        val channelName = "Wish2Go step counter"
        val chan = NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH)
        val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
        service.createNotificationChannel(chan)
    }


    var builder = NotificationCompat.Builder(this, CHANNEL_ID)
        .setOngoing(true)
        .setContentTitle("Counting steps")
        .setContentText("Open the app to see how are you doing.")
        .setSmallIcon(R.mipmap.ic_launcher_round) //Missing this was the issue 
        .setPriority(NotificationCompat.PRIORITY_HIGH)

    var notification = builder.build()
    notification.flags = Notification.FLAG_ONGOING_EVENT
    startForeground(1001, notification)

}

After setting the small Icon the notification acted as expected .
