Display a view only once on application first run

Question

I'm working on Xamarin Android and I need to show a images carousel when application start.

I have seen some implementations with Java Shared Preferences, but I don't know how to do this with Xamarin. Could you help me?

Thanks a lot!

Do you make any research at all? http://stackoverflow.com/questions/26668509/how-do-i-use-sharedpreferences-in-xamarin-android — Tosin Onikute, Nov 28 '16 at 20:08

To access shared prefs on Xamarin:

ISharedPreferences prefs = PreferenceManager.GetDefaultSharedPreferences (this);

Then to check for a "firstRun" using shared preferences:

            if (prefs.GetBoolean ("firstRun", true)) {
                LaunchImagesCarousel ();
                prefs.Edit ().PutBoolean ("firstRun", false).Commit ();
            } else {
               // something else
            }

I use the same approach to display a tutorial of carousel images if its user's first time opening the app.

If this is deemed redundant, unnecessary and/or likely answered elsewhere, please do remove it.

With Xamarin Forms you can do VersionTracking.IsFirstLaunchEver
