Splash Screen

KAppMaker ships a native launch screen on both Android and iOS — no third‑party library. Each platform uses its own built‑in mechanism, so the splash appears instantly at cold start before the Compose UI loads.

Android

Uses the official androidx.core:core-splashscreen API.

• Theme Theme.App.Starting in androidApp/src/main/res/values/styles.xml.
• The background is @color/windowBackgroundColor — the same as the app window — so the splash hands off to your UI with no color flash. The icon is the adaptive launcher icon @mipmap/ic_launcher. (The system masks the splash icon to a circle; adaptive icons are built for that, so it stays crisp and uncropped — a full-bleed brand logo would lose its corners. The native theme also can't reference Compose resources, only res/ ones.) Your brand logo (ic_logo) is shown uncropped by the in-app Compose splash (the onboarding loading screen).
• Wired via android:theme="@style/Theme.App.Starting" on AppActivity, plus installSplashScreen() (before super.onCreate()) in App.android.kt. After launch, postSplashScreenTheme hands off to AppTheme.

To keep the splash on screen while the app finishes loading:

installSplashScreen().setKeepOnScreenCondition { !isReady }

iOS

Uses the declarative UILaunchScreen key in iosApp/iosApp/Info.plist (iOS 14+, no storyboard, no .xcodeproj changes).

iOS can't point a launch screen at the AppIcon set, so the splash logo is a single image you replace:

• Logo → iosApp/iosApp/Assets.xcassets/ic_logo.imageset/ic_logo.png
• Background → iosApp/iosApp/Assets.xcassets/SplashBackground.colorset

The Info.plist keys reference those by name:

<key>UILaunchScreen</key>
<dict>
    <key>UIColorName</key>
    <string>SplashBackground</string>
    <key>UIImageName</key>
    <string>ic_logo</string>
    <key>UIImageRespectsSafeAreaInsets</key>
    <true/>
</dict>

Rebrand checklist

Platform	Background	Logo
Android	windowBackgroundColor (colors.xml) — same as the app window	@mipmap/ic_launcher — the adaptive launcher icon (circle-masked)
iOS	SplashBackground.colorset	ic_logo.imageset/ic_logo.png — your brand logo

Tip: keep the iOS SplashBackground color in sync with your Android windowBackgroundColor (the app window background) so both platforms look identical and transition seamlessly.

The brand logo shown right after the native splash (the in-app Compose splash, sign-in, and onboarding) is designsystem/.../composeResources/drawable/ic_logo.webp. Replace that one file to rebrand the in-app logo across all platforms — it's the same asset the native iOS launch screen uses (copied to ic_logo.imageset/ic_logo.png, since the launch screen can't read Compose resources).
