Xamarin Forms - Android - initialize libraries in splash activity (before main activity) - xamarin

Question

My splash screen is Lottie animation, during 3-sec animation I am trying to initialize all I can in the background thread, so I put everything from MainActivity before LoadApplication method in this new activity, just wanted to put everything I can inside splash animation time
here is my splash activity class
[Activity(Label = "MyName", Theme = "#style/MyName.Splash", MainLauncher = true, NoHistory = true)]
public class SplashActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity, IAnimatorListener
{
private Com.Airbnb.Lottie.LottieAnimationView animationView;
public void OnAnimationCancel(Animator animation)
{
}
public void OnAnimationEnd(Animator animation)
{
//StartActivity(new Intent(Application.Context, typeof(MainActivity)));
StartActivity(new Intent(this, typeof(MainActivity)));
Finish(); //if I remove this I got 1-2 sec white screen
}
public async void OnAnimationStart(Animator animation)
{
await Task.Run(() =>
{
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
global::Xamarin.Forms.FormsMaterial.Init(this, savedInstanceState);
OneSignal.Current.StartInit(API_KEY).InFocusDisplaying(OSInFocusDisplayOption.Notification).EndInit();
FFImageLoading.Forms.Platform.CachedImageRenderer.Init(enableFastRenderer: true);
Rg.Plugins.Popup.Popup.Init(this); // ------ this became problem
MainActivity.AppInstance = new App(); //even create Xam App here but don't show it yet
});
}
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.SplashLayout);
animationView = FindViewById<Com.Airbnb.Lottie.LottieAnimationView>(Resource.Id.animation_view);
animationView.AddAnimatorListener(this);
}
}
I put init methods inside the background thread because if it is on the main thread my animation is not fluid.
After the animation ends, I start main activity and show my app
main activity code
[Activity(Label = "MyName", Icon = "#mipmap/ic_launcher", Theme = "#style/MainTheme", MainLauncher = false, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
public static App AppInstance; //Xamarin App instance created on splash activity
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
LoadApplication(AppInstance);
AppInstance.Show(); //just setting MainPage = new AppShell();
}
public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Android.Content.PM.Permission[] grantResults)
{
Xamarin.Essentials.Platform.OnRequestPermissionsResult(requestCode, permissions, grantResults);
base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
everything is working fine, except Rg plugin
if I move Rg.Plugins.Popup.Popup.Init(this); into main activity then it's working.
So my question is am I doing wrong to initialize platform-specific libraries in splash activity, and I why only Rg plugin doesn't work I see in init it asks for Context same as other libraries so I did initialize it with this keyword and starting main activity with this keyword
Should I do it some other way, init libraries while my animation is playing, because every sec counts when you start the application.
Context which Main activity is created is it different one from splash activity?
I even tried to replace all this with Application.Context
