Xamarin：RegisterActivityLifecycleCallbacks - 预启动时出错：java.lang.UnsatisfiedLinkError：未找到 void

如何解决Xamarin：RegisterActivityLifecycleCallbacks - 预启动时出错：java.lang.UnsatisfiedLinkError：未找到 void

如果有代码实现。在 VS 调试运行上，没有错误。应用程序也可以运行，但在 Google-Play Sorte 的预发布中，收到此错误消息：

"java.lang.UnsatisfiedLinkError: 没有找到 void 的实现 crc6438c23e30aebeb336.MainApplication.n_onCreate()（试过 Java_crc6438c23e30aebeb336_MainApplication_n_1onCreate 和 Java_crc6438c23e30aebeb336_MainApplication_n_1onCreate__)"

代码：

...
 [Application]
    public partial class MainApplication : Application,Application.IActivityLifecycleCallbacks
    {
        public static bool IsApplicationInForeground { get; private set; }

        public MainApplication(IntPtr handle,JniHandleOwnership transer)
          :base(handle,transer)
        {
        }

        public override void OnCreate()
        {
            base.OnCreate();

            try { RegisteractivityLifecycleCallbacks(this); } catch { }
            
            //A great place to initialize Xamarin.Insights and Dependency Services!
        }

        public override void OnTerminate()
        {
            base.OnTerminate();
            try { UnregisteractivityLifecycleCallbacks(this); } catch { }
        }

        public void OnActivityCreated(Activity activity,Bundle savedInstanceState) //?
        {
            CrossCurrentActivity.Current.Activity = activity;
        }

        public void OnActivityDestroyed(Activity activity) //?
        {
        }

        public void OnActivityPaused(Activity activity) //?
        {
        }

        public void OnActivityResumed(Activity activity)
        {
            CrossCurrentActivity.Current.Activity = activity;
            IsApplicationInForeground = true;
        }

        public override void OnTrimMemory(TrimMemory level)
        {
            IsApplicationInForeground &= level != TrimMemory.UiHidden;

            base.OnTrimMemory(level);
        }

        public void OnActivitySaveInstanceState(Activity activity,Bundle outState) //?
        {
        }

        public void OnActivityStarted(Activity activity) //?
