SplashScreen not full screen when exist on Android

I have application with white color status bar and navigation bar. I have define a Splash theme like this.

<style name="Theme.MySplash" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">#00f</item>
    <item name="windowSplashScreenAnimatedIcon">@drawable/ic_baseline_play_arrow_24</item>
    <item name="windowSplashScreenAnimationDuration">200</item>

    <item name="postSplashScreenTheme">@style/Theme.AppTheme</item>
</style>

<style name="Theme.AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <item name="android:statusBarColor">#fff</item>
    <item name="android:navigationBarColor">#fff</item>
</style>

MainActivity

class MainActivity : AppCompatActivity() {

    var keepSplashScreen = true

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val splashScreen = installSplashScreen()

        splashScreen.setOnExitAnimationListener { splashScreenProvider ->
            val fadeAnim = ObjectAnimator.ofFloat(
                splashScreenProvider.view, View.ALPHA, 1f, 0f
            )
            fadeAnim.duration = 4000L
            fadeAnim.interpolator = AccelerateInterpolator()
            fadeAnim.doOnEnd { splashScreenProvider.remove() }
            fadeAnim.start()
        }
        splashScreen.setKeepVisibleCondition { keepSplashScreen }
        setContentView(R.layout.activity_main)

        Handler(Looper.getMainLooper()).postDelayed({
            keepSplashScreen = false
        }, 3000)
    }
}

SplashTheme working well on device Android 12 (Pixel 4XL) but on Android 8 (Xiomi A2), the SplashTheme won't display full screen when it exist.

From this video, when SplashScreen start exist (fade animation), the white status bar and navigation bar is display (on Android 12, SplashScreen always fullscreen while exist). How can I make the SplashScreen always fullscreen on Android < 12?

I think the problem maybe you do not use the compact library. If you’re not using the support library, your splash screen will exactly have the same old look in lower versions as you had before.

implementation 'androidx.core:core-splashscreen:1.0.0-alpha01'

the SplashScreen actually use a frame layout that contains a image view

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="false">

  <ImageView
      android:id="@ id/splashscreen_icon_view"
      android:layout_width="?attr/splashScreenIconSize"
      android:layout_height="?attr/splashScreenIconSize"
      android:layout_gravity="center"/>

</FrameLayout>

Try this:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Write it inside your onCreate Method. For more, Read this.
