Introduction to the Application Starting Window

The starting window is the first page displayed when an application is launched from a cold start. It remains visible until the application process starts or the application content is fully loaded. This window plays a crucial role in presenting the brand identity of the application. You can customize resources to display a unique logo, thereby strengthening user recognition of the product.

Use Scenarios

You are advised to consider the display effect in the following scenarios when designing the starting window.

  • Application cold start

    When the application is launched without any background processes running, the starting window is shown first. There is a 200 ms fade-out animation transitioning from the starting window to the application content.

  • Widgets on the multitasking screen

    If an application transitions to the background during startup, its starting window is displayed on the multitasking screen.

  • Application exit

    If an application is destroyed and no snapshot is generated on the system, the starting window is displayed during the application exit.
