One of the new features that is coming to Android users with the upcoming new build (Android 12) is an animated icon on the splash screen of certain apps being opened. For example, when you tap on a compatible app, the icon will expand until it reaches all four corners of the display. Google says that the animated icon startup will “deliver a more consistent and delightful experience.”
On the Android developers web page, Google writes that the new animated icon startup “includes an into-app motion at launch, a splash screen showing your app icon, and a transition to your app itself. Google writes that “The new experience brings standard design elements to every app launch, but it’s also customizable so your app can maintain its unique branding.”
