在Xamarin表单中重写OnActivated的正确方法是什么？我得到了意想不到的结果

using Xamarin.Forms;

public partial class App : Application
{
    protected override void OnStart()
    {
        // Handle when your app starts
    }

    protected override void OnSleep()
    {
        // Handle when your app sleeps
    }

    protected override void OnResume()
    {
        // Handle when your app resumes
    }

    protected override void OnActivated()
    {
        // Handle when your app is activated (from background to foreground)
        // Perform necessary operations here
    }
}
