Son olarak; çoğu splash screen pat diye kapanıyor. bunun için attığım tweetlerdeki tüm yapıyı birleştirip animasyon (çapraz geçiş yumuşak geçiş vs) yapmanız lazım özet gerekirse (yine chatgpt) IInstagram’ın splash geçişi 3 parçadan oluşur: Launch: OS seviyesinde statik splash (iOS’ta LaunchScreen.storyboard, Android’de windowBackground). Arka plan logo, hızlı açılır. Handoff: App açıldığında ilk ekranın “ilk frame”i hazırlanır. Arka plan rengi ve status bar splash ile aynı → “pat diye” geçiş olmaz. Crossfade: Statik splash kaybolurken app içi splash üstte opacity ile fade-out olur (200–350 ms). Bazı build’lerde 0.98→1.0 scale eklenir, daha yumuşak his verir. Neden akıcı? Görsel tutarlılık (renk, logo, status bar) Kısa ease-out fade İçerik hazırlığı splash arkasında İnce ayarlar: Fade süresi: 220–300 ms Easing: ease-out cubic Scale: 0.98→1.0 (opsiyonel) RNBootSplash.hide({ fade:false }) → fade’i sen yönet Animasyonda useNativeDriver:true Instagram aslında “launch → handoff → crossfade” üçlüsüyle splash geçişini fark ettirmeden çözüyor.

It’s a matter of material sampling size. The “glassy” materials (NSVisualEffectView, SwiftUI Material) have to apply expensive Gaussian blur, while windowBackground only calculates a single color (presumably from a heavily downsampled texture).

3⃣ Customize splash screen By default, SplashScreen uses the windowBackground of your theme if it's a single color and the launcher icon. The customization of the splash screen is done by adding attributes to the app theme.

We fake the splash screen by creating an xml drawable that we assign to the windowBackground. But on <23, the drawable size can only match its content and gets scaled to fit the screen.

Android 12 adds new APIs for seamlessly transitioning from your windowBackground to your content. Many of these APIs are now available back to API 23 via the new Core Splashscreen 1.0.0-alpha01. developer.android.com/jetpac…

The splash screen is drawn by the system before your app is started so the latency is better. The windowBackground trick was more a hack to create a splash screen. If you don't use trampoline activity, you shouldn't see two splash screens.

... This can be done by doing a version check in your code for API > 31 and creating a values-v31/theme.xml file where you can override attributes used for splashscreen (windowBackground). 8/

Te recomiendo: - Usar svg para tus drawables - ImageView ajustado por guidelines en constraintlayout para que se adapte a multiples pantallas - Usar un windowbackground solo para las pantallas comunes, el resto dejaselo a cada layout porque te limita el theme para algo concreto

うーわ windowBackgroundでスプラッシュテーマ設定してスプラッシュ画面を出してるんだけど、画像を真ん中に配置したはずなのになんかずれてるなーと思ったら、windowBackgroundの有効表示範囲はNavifationBarとかStatusBarも含むらしい 悩んだー

launch timeの最適化、このページが参考になった。Themed launch screensの節で言及されているwindowBackgroundを使う方法を知らなかったので試したらとても良かった developer.android.com/topic/…

windowbackground に animated vector drawable 設定したらちゃんとうごく？

@aprilzero set windowBackground to the activity's theme.

Status bar is changing color to the 'windowBackground' instead of using 'colorPrimaryDark' #xamarin ift.tt/2ksh4hY

sdk21以上だけwindowBackgroundの指定が抜けていて、sdk23ではR: 250, G: 250, B: 250になっておりました…

あちこち適当に background をView 書いてて辛かったのを windowbackground に統一したのでつらみも消えたしオーバードローもなくなったし最高

@droidmed Difference between calling windowDisablePreview and setting windowBackground attribute.

@Louis_CAD Difference between calling windowDisablePreview and setting windowBackground attribute. See here : medium.com/google-developers…

@iamcaner Still valid today. Calling windowDisablePreview != setting windowBackground attribute. medium.com/google-developers…
