Android Question Full screen with SDK 36 doesn't work.

[Cleidson]

Hello everyone,
I updated an app to target SDK 36, and something happened that I need to understand.
When the app targeted SDK 35 and we used `<item name="android:windowOptOutEdgeToEdgeEnforcement">true</item>` in the manifest, the app screen occupied the entire display area. You could adjust the layout to prevent the device's navigation bars from overlapping the app's controls.
With the update, I expected this behavior to persist without needing to declare anything in the manifest. However, the app's behavior differed from my expectations.

Below are screenshots from different Android versions:

Android 12 and Android 15 with the manifest declaration:

Android 16 without the manifest declaration:

Here is the manifest declaration:

'================ DEFAULT =================
AddManifestText(
<uses-sdk android:minSdkVersion="23" android:targetSdkVersion="36"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)

SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:allowBackup, "false")
SetApplicationAttribute(android:usesCleartextTraffic, "false")
'SetApplicationAttribute(android:theme, "@style/MyAppTheme")
SetApplicationAttribute(android:theme, "@style/LightTheme")

'================ THEMES =================
CreateResource(values, colors.xml,
<resources>
    <color name="actionbar">@android:color/transparent</color>
</resources>
)

CreateResource(values, theme.xml,
<resources>
    <style name="LightTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:colorPrimary">@color/actionbar</item>
        <item name="android:windowActionBarOverlay">true</item>
    </style>
</resources>
)

'CreateResource(values, theme.xml,
'<resources>   
'    <style name="MyAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
'    </style>
'   
'    <style name="LightTheme" parent="Theme.AppCompat.Light">
'        <item name="android:actionMenuTextAppearance">@style/LowerCaseMenu</item>
'        <item name="android:windowOptOutEdgeToEdgeEnforcement">true</item>
'    </style>
'   
'    <style name="LowerCaseMenu" parent="android:TextAppearance.Material.Widget.ActionBar.Menu">
'        <item name="android:textAllCaps">false</item>
'    </style>
'   
'    <style name="Theme.Hidden" parent="@android:style/Theme.NoDisplay" />
'    <style name="Theme.PlayCore.Transparent" parent="@android:style/Theme.Translucent.NoTitleBar" />
'</resources>
')

I noticed an intriguing situation: when rotating the phone to landscape mode and back to portrait mode, the app switched to full-screen behavior.

Thank you in advance for your attention.
