説明

Informs about significant changes in the application's memory usage.

This event occurs when there are significant changes in the application's memory usage, such as an increase to a dangerous level or a drop to a much safer level. This event is supported on iOS, Android, and Universal Windows Platform (UWP). Note, that not all platforms support all possible values, so it's not recommended to rely on receiving particular values. Only critical memory level is supported everywhere.

using System;
using UnityEngine;

public class Sample : MonoBehaviour { void Start() { Application.memoryUsageChanged += OnMemoryUsageChanged; }

void OnMemoryUsageChanged(in ApplicationMemoryUsageChange newUsage) { if (newUsage.memoryUsage == ApplicationMemoryUsage.Critical) { // release resources here Resources.UnloadUnusedAssets(); GC.Collect(); } } }

This code sample shows how to perform garbage collection if the application is critically low on memory.
