gles2实时墙纸转换为c#（xamarin）符合错误“；。。。mono.android.TypeManager无法应用于

我正在尝试用c#中的xamarin编写android live墙纸。
为此，我将这里找到的服务代码转换为c:


（此处直接跳到java实现：）

编译后，我得到错误：

mono.android.TypeManager中的Activate（java.lang.String、java.lang.String、java.lang.Object、java.lang.Object[]）不能应用于（java.lang.String、java.lang.String、com.[redacted].OpenGles2WallperService.OpenGles2WallperService_OpenGLES2Engine、java.lang.Object[]）mono.android.TypeManager.Activate（“com.[redacted].opengles2wallperservice/OpenGLES2Engine，GameUtilClassLibrary，Version=1.0.0，Culture=neutral，PublicKeyToken=null，“com.[redacted].wallperserviceutil.opengles2wallperservice，GameUtilClassLibrary，Version=1.0.0.0，Culture=neutral，PublicKeyToken=null”，这是新的java.lang.Object[]{opengles2wallpersservice.this}）；D:\[redacted]\obj\Debug\android\src\com\[redacted]\wallperviceutil\opengles2wallperservice.java
这是我的c#实现。。。抱歉，篇幅太长：

我的目标是sdk版本8，并使用Visual Studio 2012。

非常感谢您的帮助。

这是我们的Android可调用包装器生成器代码中的一个错误：我们不能正确地支持C#中的“中间”非静态内部类。具体来说，

glwallperservice.Engine

正确生成，但

opengles2wallperservice.OpenGLES2Engine

不正确

请在提交一个bug。
