How to run code after a delay in Xamarin Android

Question

I'm trying to show some code after a delay in my Android app.
The Java code for doing this is something like this:

new Handler().postDelayed(new Runnable()
{
   @Override
   public void run()
   {
     // your code that you want to delay here
   }
}, 1000/* 1000ms = 1sec delay */);

How do I do this in Xamarin.Android with C#?

You can try this:

Handler h = new Handler();
Action myAction = () => 
{
    // your code that you want to delay here
};

h.PostDelayed(myAction, 1000);

@MaximeEsprit you can use C# `Task.Delay` https://stackoverflow.com/a/25188225/719212 – ductran May 04 '18 at 03:25

I advise you to use cross-platform timer like AdvancedTimer. Check:github repo

API Usage

To gain access to the Timer class simply use the dependency service:

IAdvancedTimer timer = DependencyService.Get<IAdvancedTimer>();

You MUST call initTimer for timer initialization;

timer.initTimer(3000, timerElapsed, true);

initTimer(interval, Eventhandler function, AutoReset);

Methods

timer.startTimer();

timer.stopTimer();

timer.getInterval()

timer.setInterval(5000);

timer.isTimerEnabled();
