Xamarin forms splash screen issue - xamarin

Question

A black screen with app title is showing when minimizing the app while loading splash screen , also the first screen will display after some time. Here is my splash activity and main activity classes.
[Activity(Theme = "#style/Theme.Splash", Icon = "#drawable/icon", MainLauncher = true, NoHistory = true,
ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation,
ScreenOrientation = ScreenOrientation.Behind)]
public class SplashActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
var dpWidth = Resources.DisplayMetrics.WidthPixels/Resources.DisplayMetrics.Density;
RequestedOrientation = dpWidth > 700 ? ScreenOrientation.Unspecified : ScreenOrientation.Portrait;
ThreadPool.QueueUserWorkItem(o => LoadActivity());
}
private void LoadActivity()
{
RunOnUiThread(() => StartActivity(typeof(MainActivity)));
}
public override void OnBackPressed()
{
Environment.Exit(0);
}
}
[Activity(Label = "HACCP", ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
public class MainActivity : FormsApplicationActivity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
ActionBar.SetIcon(Android.Resource.Color.Transparent);
Forms.Init(this, bundle);
// some function //
LoadApplication(new App());
}
}

Answer 1

You tagged Xamarin.Forms so it should be as simple as..
class App : Application
{
public App()
{
MainPage = new MySplashPage();
}
}
class MySplashPage : ContentPage
{
public MySplashPage()
{
Task.Delay(3000); //show my pretty splash for 3 seconds
Application.Current.MainPage = new MyOtherSpiffyPage();
}
}

Answer 2

Not certain if the activity attribute ScreenOrientation = ScreenOrientation.Behind) is causing any issues, we don't use that in our apps.
Here is a "standard" splash activity we do use, letting Xamarin.Android take care of timing etc:
public class SplashActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Start main.
StartActivity(typeof(MainActivity));
}
}
You might try simplifying your app in similar fashion.
