Some time ago I asked (and solved) for the same question for the iOS version fo my app (Cordova iOS 6.1.1 white splash screen), now I have the same issue for the Android one.
I'm build the apk with an online tool using cordova-cli-10.0.0
The app runs but I see only a white screen instead of my splash screen file.
In my config.xml file I have the following splash screen settings (I skipped other settings here, if needed I can post them):
<preference name="SplashScreenDelay" value="3000" />
<platform name="android">
<splash src="res/screen/android/PackageIcons.Android.splash_480_800.png" density="hdpi"/>

</platform>
I added the xxhdpi and xxxhdpi files and also the dark mode settings, but it is still a white splash screen. Can you please help me here?

Maybe use proper file naming, rename your
PackageIcons.Android.splash_1280_1920.png
To
PackageIcons_Android_splash_1280_1920.png
I also don't see <plugin name="cordova-plugin-splashscreen" spec="^6.0.0" /> you need to install it
