The implementation on Android devices allows the application content to extend and draw behind the system bars (status bar and navigation bar). This creates a more visually appealing and immersive experience for the user by blending the application interface with the device’s system UI. A common example is a full-screen image that extends seamlessly behind the status bar, making it appear as if the image is part of the device’s bezel-less screen.
This design approach enhances the user interface by reducing visual distractions and maximizing screen real estate available to the application. This approach has evolved as Android has matured, initially requiring specific flags and API calls, and later becoming more streamlined with newer Android versions. Historically, this provided a competitive advantage for applications, allowing them to stand out through an enhanced visual design.
