Question

Hi I am trying to build an application in xamarin forms using PCL. I am trying to logout user from my app if the app is idle more than 10minute or more. I tried it by events

Tweaked @Wolfgang version

public sealed class SessionManager
{
    static readonly Lazy lazy =
        new Lazy(() => new SessionManager());

    public static SessionManager Instance { get { return lazy.Value; } }
    private Stopwatch StopWatch = new Stopwatch();

    SessionManager()
    {
        SessionDuration = TimeSpan.FromMinutes(5);
    }

    public TimeSpan SessionDuration;

    public void EndTrackSession()
    {
        if (StopWatch.IsRunning)
        {
            StopWatch.Stop();
        }
    }

    public void ExtendSession()
    {
        if (StopWatch.IsRunning)
        {
            StopWatch.Restart();
        }
    }

    public void StartTrackSessionAsync()
    {
        if (!StopWatch.IsRunning)
        {
            StopWatch.Restart();
        }

        Xamarin.Forms.Device.StartTimer(new TimeSpan(0, 0, 2), () =>
        {
            if (StopWatch.IsRunning && StopWatch.Elapsed.Minutes >= SessionDuration.Minutes)
            {
                Xamarin.Forms.Device.BeginInvokeOnMainThread(async () =>
                {
                    await Prism.PrismApplicationBase.Current.Container.Resolve().NavigateAsync("/Index/Navigation/LoginPage");
                });

                StopWatch.Stop();
            }

            return true;
        });

    }

}

Under main activity added the below

    public override void OnUserInteraction()
    {
        base.OnUserInteraction();
        SessionManager.Instance.ExtendSession();
    }
