Display Full-Screen API

Overview

This guide explains how to use specific system APIs to hide the status bar and navigation bar, enabling a full-screen display on Android devices.

Be aware that using these APIs affects the entire system, not just your application. When you hide the status bar or navigation bar, it remains hidden across all system interfaces and applications.
