AndroidApplication.onWindowInsetsChanged

Description

A callback to detect changes in the window insets when the application is running.

Notes:

• The callback is only supported on Android 11 (API 30) or later versions. On older devices, you need to detect changes in the insets manually as demonstrated in the following code example.
• Querying insets manually using AndroidApplication.currentWindowInsets is a slow operation.

using UnityEngine;
using UnityEngine.Android;

public class Controller : MonoBehaviour
{
    private bool InsetsCallbackSupported => AndroidBuild.Version.apiLevel >= 30;
    private bool StatusBars;
    private bool NavigationBars;

    public void Start()
    {
        if (InsetsCallbackSupported)
            AndroidApplication.onWindowInsetsChanged += OnInsetsChanged;
        else
        {
            var insets = AndroidApplication.currentWindowInsets;
            StatusBars = insets.IsVisible(AndroidWindowInsets.Type.StatusBars);
            NavigationBars = insets.IsVisible(AndroidWindowInsets.Type.NavigationBars);
        }
    }

    public void Update()
    {
        if (!InsetsCallbackSupported)
        {
            var insets = AndroidApplication.currentWindowInsets;
            var currentStatusBars = insets.IsVisible(AndroidWindowInsets.Type.StatusBars);
            var currentNavigationBars = insets.IsVisible(AndroidWindowInsets.Type.NavigationBars);
            if (StatusBars != currentStatusBars || NavigationBars != currentNavigationBars)
            {
                OnInsetsChanged(insets);
                StatusBars = currentStatusBars;
                NavigationBars = currentNavigationBars;
            }
        }
    }

    public void OnDisable()
    {
        if (InsetsCallbackSupported)
            AndroidApplication.onWindowInsetsChanged -= OnInsetsChanged;
    }

    void OnInsetsChanged(AndroidWindowInsets insets)
    {
        Debug.Log($"NavigationBars visible " + insets.IsVisible(AndroidWindowInsets.Type.NavigationBars));
        Debug.Log($"StatusBars visible " + insets.IsVisible(AndroidWindowInsets.Type.StatusBars));
    }
}
