Component used: androidx.core:core-splashscreen Version used: 1.0.0-beta01 Devices/Android versions reproduced on: AVD running Android 8, 10, and 12.

When setting a custom exit animation via setOnExitAnimationListener, the timing of the theme change for navigation/status bars are inconsistent across Android versions:

• API 31: The colors change when the splash screen is fully .remove()-ed.
• API <31: The colors change the moment the exit listener is called.

I'm aware API <31 uses a custom implementation designed to imitate the new behavior. However, I feel this inconsistency can be reasonably addressed. I prefer the behavior of API 31.

Example and videos:

Using the following theme:

    <style name="Theme.MyApplication" parent="Theme.AppCompat.NoActionBar">
        <item name="android:statusBarColor">@android:color/holo_blue_light</item>
        <item name="android:navigationBarColor">@android:color/holo_red_light</item>
    </style>
    <style name="Theme.MySplash" parent="Theme.SplashScreen">
        <item name="windowSplashScreenBackground">@color/cardview_dark_background</item>
        <item name="windowSplashScreenAnimatedIcon">@drawable/ic_still_loader</item>
        <item name="postSplashScreenTheme">@style/Theme.MyApplication</item>
    </style>

With this theme, I expect the navigation bars to be transparent during the splash screen, and change to the holo colors after my exit animation. This works as expected on 31, but not on the others.

I intentionally delay the start of my animation to demonstrate the inconsistency. The attachments are examples from API 31 and API 29 (see filenames).
