NotSupportedException无法激活JNI Handle - MvvmCross

我最近在项目中将MvvmCross从3.5.1更新到了4.1.4，并发布了应用更新。NotSupportedException无法激活JNI Handle - MvvmCross

之后，我从Xamarin Insights看到，有很多用户体验;

Could not activate JNI Handle 0xffb35af8 (key_handle 0xe888654) of Java type 'md53997af0c1a24144057e197743f9f827a/HomeView' as managed type 'package.name.HomeView'几乎所有活动都有其各自的活动名称。所有这些活动都是Mvx活动。

我Setup.cs -

public class Setup : MvxAndroidSetup 
{ 
    public Setup(Context applicationContext) 
     : base(applicationContext) 
    { 
    } 

    protected override IMvxApplication CreateApp() 
    { 
     return new MVVM.App(); 
    } 

    protected override IMvxTrace CreateDebugTrace() 
    { 
     return new MvxDebugTrace(); 
    } 

    protected override MvvmCross.Droid.Views.IMvxAndroidViewPresenter CreateViewPresenter() 
    { 
     var presenter = new MyViewPresenter(); 

     Mvx.RegisterSingleton<IMvxViewPresenter>(presenter); 

     return presenter; 
    } 

    protected override void FillTargetFactories(MvvmCross.Binding.Bindings.Target.Construction.IMvxTargetBindingFactoryRegistry registry) 
    { 
     registry.RegisterCustomBindingFactory<View>(
       "ShowMe", 
       v => new ViewScalingCustomBinding(v)); 
     registry.RegisterCustomBindingFactory<View>(
       "ScaleMe", 
       v => new ViewSizingCustomBinding(v)); 
     registry.RegisterCustomBindingFactory<View>(
       "CustomFont", 
       v => new FontCustomBinding(v)); 
     registry.RegisterCustomBindingFactory<View>(
       "OtherCustomFont", 
       v => new FontDincCustomBinding(v)); 
     registry.RegisterCustomBindingFactory<View>(
       "ImageResize", 
       v => new ImageResizeCustomBinding(v)); 
     base.FillTargetFactories(registry); 
    } 

    protected override IMvxPluginConfiguration GetPluginConfiguration(Type plugin) 
    { 
     if (plugin == typeof(MvvmCross.Plugins.DownloadCache.Droid.Plugin)) 
     { 
      return new MvvmCross.Plugins.DownloadCache.Droid.MvxDownloadCacheConfiguration() 
      { 
       CacheName = "Pictures.MvvmCross", 
       CacheFolderPath = "../Library/Caches/Pictures.MvvmCross/", 
       MaxFiles = 500, 
       MaxFileAge = TimeSpan.FromDays(1), 
       MaxInMemoryBytes = 4000000, // 4 MB 
       MaxInMemoryFiles = 1, 
       MaxConcurrentDownloads = 10, 
       DisposeOnRemoveFromCache = false 
      }; 
     } 

     return null; 
    } 
}

什么可能会造成这个问题？

你可以展示其中的一个Activites吗？也许你的Setup.cs？不止4件事情发生了变化，所以也许活动头文件有问题。 – Cyriac

除了命名空间和命名空间相关的东西，我没有改变Setup.cs中的任何东西，但我可以将它添加到问题中。除了标签和屏幕方向外，活动标题还没有任何特定内容。 –

它只出现在一些用户，你自己没有这个问题？ – Cyriac

我有没有使用任何自定义视图的异常。只是试图清理这个项目，它解决了我的问题，但是仍然有这样的事情让我害怕使用Xamarin。
