thank you for your useful time. after some articles and your helpful link. i find below code and it works fine... but problem is that it always show the "service start". how can I hide this notification? i this want app keep sending message to client but first it does not show the foreground service "service started" notiifcation.
private Handler handler;
private Action runnable;
private bool isStarted;
private int DELAY_BETWEEN_LOG_MESSAGES = 5000;
private int NOTIFICATION_SERVICE_ID = 1001;
// private int NOTIFICATION_AlARM_ID = 1002;
private int NOTIFICATION_AlARM_ID = 1;
private string NOTIFICATION_CHANNEL_ID = "1003";
private string NOTIFICATION_CHANNEL_NAME = "MyChannel";
public int i;
public override void OnCreate()
{
base.OnCreate();

handler = new Handler();

//here is what you want to do always, i just want to push a notification every 5 seconds here
runnable = new Action(() =>
{
if (isStarted)
{
DispatchNotificationThatAlarmIsGenerated("I'm running"+ i++);
handler.PostDelayed(runnable, DELAY_BETWEEN_LOG_MESSAGES);
NOTIFICATION_AlARM_ID++;
}
});
}

public override StartCommandResult OnStartCommand(Intent intent, StartCommandFlags flags, int startId)
{
if (isStarted)
{
// service is already started
}
else
{
CreateNotificationChannel();
DispatchNotificationThatServiceIsRunning();
handler.PostDelayed(runnable, DELAY_BETWEEN_LOG_MESSAGES);
isStarted = true;
}
return StartCommandResult.Sticky;
}

public override void OnTaskRemoved(Intent rootIntent)
{
//base.OnTaskRemoved(rootIntent);
}

public override IBinder OnBind(Intent intent)
{
// Return null because this is a pure started service. A hybrid service would return a binder that would
// allow access to the GetFormattedStamp() method.
return null;
}

public override void OnDestroy()
{
// Stop the handler.
handler.RemoveCallbacks(runnable);

// Remove the notification from the status bar.
var notificationManager = (NotificationManager)GetSystemService(NotificationService);
notificationManager.Cancel(NOTIFICATION_SERVICE_ID);

isStarted = false;
base.OnDestroy();
}

private void CreateNotificationChannel()
{
//Notification Channel
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, NOTIFICATION_CHANNEL_NAME, NotificationImportance.Max);
notificationChannel.EnableLights(true);
notificationChannel.EnableVibration(true);
notificationChannel.SetVibrationPattern(new long[] { 100, 200, 300, 400, 500, 400, 300, 200, 400 });


NotificationManager notificationManager = (NotificationManager)this.GetSystemService(Context.NotificationService);
notificationManager.CreateNotificationChannel(notificationChannel);
}

//start a foreground notification to keep alive
private void DispatchNotificationThatServiceIsRunning()
{
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
.SetDefaults((int)NotificationDefaults.All)
.SetSmallIcon(Resource.Drawable.s)
.SetVibrate(new long[] { 100, 200, 300, 400, 500, 400, 300, 200, 400 })
.SetSound(null)
.SetChannelId(NOTIFICATION_CHANNEL_ID)
.SetPriority(NotificationCompat.PriorityDefault)
.SetAutoCancel(false)
.SetContentTitle("test")
.SetContentText("ervice started")
.SetOngoing(true);

my code is working well when I have the only labels but I add an image, it doesn't add an image to pdf and only convert text to pdf
