  I'm trying to reproduce some of them with no success. I only got blank screen.

  Because you didn't specify the windowBackground in style.xml. You need to create a drawable for splash screen and implement a theme.
  style.xml

  <style name="MyTheme.Splash" parent ="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowBackground">@drawable/splash_screen</item>
    ...
  </style>
  

  drawable\splash_screen.xml

  <?xml version="1.0" encoding="utf-8"?>
  <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
      <color android:color="@color/splash_background"/>
    </item>
    <item>
      <bitmap
          android:src="@drawable/splash_logo"
          android:tileMode="disabled"
          android:gravity="center"/>
    </item>
  </layer-list>

  Jarvan, thanks to reply.

  Note, I'm not using layer-list as layout for splash screen. I using LinearLayout because I need to put image and text in my splash screen.

  Any suggestion?

  I tested a basic demo about SplashScreen useing LinearLayout and it works on my side.

  [Activity(Theme = "@style/MyTheme.Splash", MainLauncher = true, NoHistory = true)]
  public class SplashActivity : AppCompatActivity
  {
      protected override void OnCreate(Bundle bundle)
      {
          base.OnCreate(bundle);
          SetContentView(Resource.Layout.layout1);
      }
  
      protected override void OnResume()
      {
          base.OnResume();
          Task startupWork = new Task(() => { SimulateStartup(); });
          startupWork.Start();
      }
      async void SimulateStartup()
      {
          await Task.Delay(2000);
          StartActivity(new Intent(Application.Context, typeof(MainActivity)));
      }
  }
  

  Here is the sample file, you can refer to it.

  After add the task "SimulateStartup" the problem was solved.

  I was calling StartActivity(new Intent(Application.Context, typeof(MainActivity))); not as as Task.

  Thank you Jarvan!

  @Jarvan Is there a way I can skip the layer-list .xml and show directly the .axml file?
