        }


        public override void OnDestroy()
        {

            base.OnDestroy();
        }
    }
}

and my oncreate on the main activity

protected override void OnCreate(Bundle savedInstanceState)
{

        if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
        {
            Handler h = new Handler();
            Action myAction = () =>
            {
                // your code that you want to delay here
                Application.ApplicationContext.StartForegroundService(intentservice);
            };
            h.PostDelayed(myAction, 1000);

        }
        else
        {


            Handler h = new Handler();
            Action myAction = () =>
            {
                // your code that you want to delay here
                this.StartService(intentservice);
            };
            h.PostDelayed(myAction, 1000);

        }
