A custom splash screen makes your progressive web app (PWA) feel more like a native app.
When a user launches your PWA from the homescreen, Android's default behavior is to display a white screen until the PWA is ready. The user may see a blank, white screen for up to 200ms. With a custom splash screen, the user sees a custom background color and your PWA's icon instead.
See Adding a Splash Screen for Installed Web Apps in Chrome 47 for more information.
Chrome for Android automatically shows your custom splash screen so long as you meet the following requirements in your web app manifest:
nameproperty is set to the name of your PWA.
background_colorproperty is set to a valid CSS color value.
iconsarray specifies an icon that is at least 512px by 512px.
- The icon exists and is a PNG.
