What kind of application do you want to do? Which Android API version is it? It would help us if you provided us with some code and additional info.
This issue is caused by Android's splash screen behavior since Android 12. Read more here (migrating) and here (general info). Please follow the steps there to show the splash screen upon startup.
If you don't want to use a splash screen, you can explicitly remove it in your res/values/styles.xml like this to get rid of the error:
<resources>
<style name="Theme.MyApp">
<!-- other attributes... -->
<item name="android:windowSplashScreenAnimatedIcon">@null</item>
<item name="android:windowSplashScreenBackground">@null</item>
<item name="android:windowSplashScreenIconBackgroundColor">@null</item>
</style>
</resources>
Remember to update your AndroidManifest.xml to use this theme. Add this inside <application>:
android:theme="@style/Theme.MyApp"
